[Histonet] For H&E staining - TBS SHUR/Stain or Leica Autostainer XL
I have and love my old Autostainer XL. Now we are offered a new TBS SHUR/Stain unit, which is attractively small, but I have never used nor seen it in person. We are a small University based lab and our space is limited. We rarely run few racks at a time. However, we must be able to run only deparaffination and only dehydration for our immunos. If any one has experience with the TBS unit, or even better, used both of them, please let me know what do you think. I would appreciate this very much Michelle ___ Histonet mailing list Histonet@lists.utsouthwestern.edu http://lists.utsouthwestern.edu/mailman/listinfo/histonet
[Histonet] Research and Clinical Labs
For 10 years I ran Histology lab for a large University. We used the same equipment and lab for both animal and human tissue. I had to certify the lab with CLEA for human tissue at one point (and this took serious work!). If you are already certified for human, using the more strict regulations which apply to human tissue, won't hurt the rest, nor increase in any way your time or effort involvement. You do it anyway. I wouldn't leave anything marked "for research" unless it has proper label with exp date etc. We received everything already fixed and most of the time in cassettes, so there was not much grossing. The processor ran the same night and everything was finished the following day. No one, during any of the inspections had trouble with this. As far as I remember, there was no question about this in any of the check lists sent to me. It was 11 years ago when I parted with my Histo lab and I am not current on the latest regulations, but as far as the technical part... there shouldn't be a problem.

[Histonet] Sirius red stain - picric acid substitute
Hi Mia, I tried few different sources of Picric acid. Unfortunately, not all of them worked. The one that is working is from Rowley Biochemical Institute - www.rowleybio.com .

[Histonet] Oil Red O for FS on Muscle
Few more things: 1. The mixed/working solution is good for 1-2 hours only. If you filter it for a long time, this might use the good working time and then you have trouble, because it just won't work well for you. I just poor the stain and the water in a glass cylinder and shake it. That's it. 2. After coverslipping, do not press on the coverslip to chase air bubbles away or this might displace the lipid droplets from their original place. 3. Look at the slides as soon as possible. In few days, you will see that the stain is changing into ugly black crystals and the longer you wait the larger the crystals = have to repeat it all over again J 4. To clean the glassware, spray All Purpose Cleaner, use a brush and warm water Michelle ___ Histonet mailing list Histonet@lists.utsouthwestern.edu http://lists.utsouthwestern.edu/mailman/listinfo/histonet
[Histonet] Oil Red O for FS on Muscle
Hi Akemi, Order the stain from Electron Microscopy Sciences - cat # 26503-02. It comes as 250 ml solution and is a lot less expensive than some other sources. I guess you can probably get it through VWR. Mix 3 parts of this stock with 2 parts dist. Water and let it stand for 10 min. Filter through coarse filter paper. I have even used paper towel with no problem. Anything finer will take forever to filter. Fix the sections with regular 10% NBF for few min. 3-5 Rinse slides in dist. Water few times Working Oil -red-O for 10 min. I use the plastic containers for shipping slides, because the stain will color the plastic and I can easily and cheaply replace those, but you can wash them and reuse them multiple times. 70% alcohol - quick rinse to clear background Dist. Water - 5 min Mayers Hematoxylin 5 min Tap water 10 min Dist. water rinse or up to 1 min Mount with Aqua Mount Never had any problems. Normal muscle will have very, very tiny droplets. We used it on rodent muscle, but it should work the same for human.

Re: [Histonet] mouse kidney frozen sectioning
Hi Andrew, You must freeze fast to avoid the needle like crystals forming from the water during freezing. Best - freeze in OCT in liquid Nitrogen. It gets worse if you keep changing the temp of the block. For example keep at -80 then bring to -20 cut than bring the temp down to remove the block from the chuck and put back at -80. Few of those will make your tissue hard to even recognize.

[Histonet] Re: Liver Tissue
Soak the faced block in room temp. water for few minutes. This will speed the intake of water. I can usually cut it at room temp if I am careful. If your paraffin is soft then you will need to soak it in room temp water first and then put ice on it and cut it. Pick up the ribbon and place on room temp dist water. While you are picking up and stretching the sections, put piece of cotton soaked in water on the face of the block as it is attached to the microtome. This way it will be soaking in place and you won't be loosing nice sections while adjusting the angle for the next ribbon. By the time you pick up all good sections, the block will be ready to be cut again. If you have good size liver, you can soak it for much longer - 5-10 min, before you start sectioning. This way the water will penetrate dipper and you will be able to easily get a very long ribbon.

[Histonet] Re: Frozen Myocardium sections
The OCT cracks if the block remains in liquid N too long. I use a plastic mold, which holds my tissue in the OCT. Float the mold on the surface of the liquid N but pull it out of there while there is still a little liquid/clear OCT (about 6-7mm in diameter) in the middle of the forming block. Put it on the counter (room temp.). As the block sits on the counter, for a minute or two, the freezing of the center takes place. The block will never crack if it is pulled out of the OCT on time.

[Histonet] Overstained Sirius Red...
Hi everybody, I have been doing Sirius Red for a while with good luck. Today we made fresh solutions and after the stain was done, the sections (rat liver) are too red. They are positive, the fibrosis is bright pink, but the background is pink as well. I got a slide back to water and distained for 2 more minutes with no luck. The only difference is the source of the saturated picric acid. On the old bottle the manufacturer is listed as Rowley Biochemical Institute (worked great) and the new one is Ricca Chemical CO. Could this be the problem? What can I do to correct this in the future? I have now 500ml of stain which is not optimal.

[Histonet] Re: DAB and Nuclear staining
Hi Melissa, We use Mayer's hematoxylin for 5 min and then rinse in tap water for at least 5 min (to blue the stain). If your DAB stain is weak, you can counterstain for even shorter time. It works great! The other option would be 1% Methil Green in 0.1M Sodium Acetate. My Methil powder is extremely old and probably this is the reason the stain is very weak, but it makes great contrast with the brown of the DAB.

[Histonet] Re: from PLEASE HELP
Hi Delia, Some time ago I used to work in a lab where I had to cut skin punch biopsies. They used to come floating in a special preservative. Unfortunately I don't remember its name, but then I had to wash them in a special wash solution for a minute. The wash solution was made by Zeus Scientific and was just citrate buffer. I am not familiar with the Michael's fixative and don't know do you have to wash after fixing. The trick was to pat dry the biopsies with Kimwipes and immerse them right away in the OCT. Then let the biopsy sit there for few minutes. You can even move the tissue in the OCT from time to time and then transfer it to a new mold with fresh OCT. Freeze in liquid Nitrogen. This way, somehow the OCT starts infiltrating the tissue and the tissue cuts together with the OCT. I used to cut it at 5 microns.

[Histonet] Re: Citadel Tissue Processor
Hi Atoska, We do only research and have low volume. We purchased a second hand one and used it for about a year. It works and does the job. It is much better than having to process manually but: The alcohols evaporate like crazy! You loose a lot. It must be in a hood. There is no heating nor vacuum. I was under the impression that there is vacuum while reading the brochure, but when the Citadel arrived, I found that it is a separate free standing unit that can be connected only with the paraffin tanks. We didn't have the room for it so we never used it and sent it back. There is no purge/clean cycle. You have to either purchase 2 extra buckets or find some other containers for the Xylene and the 100% which you will be using to manually wash the basket after the cassettes are out of it. They should also be in the hood. In a year, one of the paraffin buckets burned. The service guy told me that a repair was not worth it. A new paraffin bath is about $1200.00. Something that was good is that you only need about 1/2 gallon per station. When we had only few cassettes, we didn't even fill completely the buckets. Infiltration was fine.

Hi all, I am researching the Leica Bond Max immunostainer and I like its features as advertised. The advertisement however states that the system is completely open, but after discussing it in length with the Leica rep I am finding that this is actually not so... We are a research core and work with mice and rats. Most of the pre-made antibody are designed towards human tests, so we won't use them. Then we would still be stuck with lots of money for consumables (as I understood all sold as kits with the antibodies included). We won't be using any of the antibodies, only the rest of the solutions... Is there a way out of this trap? Is there something that I didn't understand? My question is: Does anybody use Leica Bond as an open system and use other companies antibody, buffers and antigen retrieval protocols? If you do, what have you done so far? (Would you share your protocols?) We like the BioCare products and our helpful rep :-) Did anybody purchase the Research dongle? Do we really need it? How did it help you improve your applications? I was told that depending on what I want unlocked, we would have to spend $14000 to $27000 extra for it. OUCH!!! This is not a hospital where we can charge the insurance or patients for this...
