[Histonet] Used microtome
Hi all, I am an amateur naturalist, and I'm looking for an used microtome, but working, even on old model, to be used for histological sections of samples included in paraffin. Please can anyone give me useful directions where to find it?

Re: [Histonet] shipping slides, elementary question
I pack slides in 100-slide plastic boxes, with gauze sponges laid inside the boxes on top of slide edges to ensure that they don't jiggle around inside the box. Boxes are taped shut, then packed inside a cardboard box with plenty of room for packing peanuts or bubble wrap. Never have had a problem.

I am planning to ship a bunch to a collaborator, on the order of a few hundred. I have black hinged cardboard/wood 100-slide boxes, similar to https://www.vwrsp.com/catalog/product/index.cgi?catalog_number=48452-001inE=1highlight=48452-001 will these be sufficient for shipping (provided I ensure they stay closed during transit) to avoid breakage? I have slide mailers, but they only hold a few slides. I will do that if I need to (it would be a whole lot of packaging and labeling though...), but don't want to just send a giant box and have them all broken on the other end. Maybe there's another alternative? I'm sure someone on histonet has done this before :) Thanks in advance for the advice.

Re: [Histonet] Used microtome
Hi: There are a couple of sources besides the makes and vendors but as always it is buyer beware. eBay - you can go to www.ebay.com and do a search for microtome, right now they have several for sale. The good thing about eBay is the shipping is often reasonable and you can get a good deal. The bad news is that things can be way overpriced and the sellers usually don't know what they are selling and expensive parts can be missing so you really need to know what you are doing before you buy. GoIndustry - DoveBid at http://www.go-dove.com/default.asp This is a very different deal than eBay. Here you are buying products that are surplus when a company closes or gets rid of excess equipment. Please note microtomes are used in ares outside of BioMedical. For example companies that fabricate plastic often use microtomes for testing purposes so you can find them in unexpected places. Problem is that with DoveBid shipping is totally on you - unless you are near the auction site you will need to pay a shipper to pick the item up, pack it up and ship it to you. This can easily cost $300 for a microtome so you need to know what your are doing plus you pay a buyer's premium which can range for 16% to 18%. I find equipment on DoveBid is often newer and looks to be in better shape than eBay but it costs lots more. Right now DoveBid lists 5 different microtomes: Shandon Finesse ME Leica RM2135 Biocut 2035 Reicheit-Jung 2050 Leica RM2155 Leica RM2025 My advice is to take your time and know what you are doing - Good luck in your search.

Hi, I have seen several answer suggesting eBay. Before you go there you need to know what kind of kinives you be using so you get teh correct knife blade holder. Are you using disposable knives? If so are they high or low profile? Are you planning on sharpening solid knives? What kind of block holder do you need? Are you embedding in cassettes or with forms? All of these questions need to be answered before you buy or you could end up with something you can not use or is unusable in your hands. If you know all these answers eBay could be a good way to go. I would try to talk to some of the used equipment people and be sure you are going in the correct direction.

John, would the neutral red technique work the same with unfixed tissues? The fluorophore Nick uses might not fluoresce after formalin fixation.

Teri Johnson, HT(ASCP)QIHC Managing Director, Histology Facility Stowers Institute for Medical Research Kansas City, MO Neutral red (CI 50040) is an excellent fluorescent Nissl stain: 0.002%, in water, for 5 minutes; dehydrate, clear, and mount in DPX or another non-fluorescent resinous medium. With excitation by either near-UV or blue light (range 325-500nm) the Nissl substance and nuclei fluoresce yellow-orange. Reference: Allen, D. T. Kiernan, J. A. 1994. Permeation of proteins from the blood into peripheral nerves and ganglia. Neuroscience 59(3):755-764. We used this very dilute neutral red as a fluorescent counterstain for paraffin and cryostat sections of formaldehyde-fixed tissues from rats that had received iv injections of rhodamine-labelled albumin (green excitation, orange-red emission, localization mostly extracellular).

Re: [Histonet] flattening tissue surface
Cut very thin (about 2 µm) and let the sections expand well before taking them from the water bath. After that shake them and put the slides vertical on their smaller side (1 inch) for 15 minutes. Take to the oven at 60ºC for 10 minutes and proceed as usual. You could also buy a Kurabo S200 sectioning robot that has been found to be specially useful for the type of work you are describing (better than manual sectioning).

Re: [Histonet] Podoplanin D2-40
Are your fluids initially fixed in alcohol before the cell block is prepared? If so, that can reduce immunoreactivity for some proteins. If you can, I would recommend trying to decrease the sensitivity of your antigen retrieval. I am a strong proponent of Personalized antigen retrieval (adjusting the retrieval based on the type of specimen, fixation, and the length of fixation). I do not have any experience with Ventana's instruments, but on our Bond Max and Bond III instruments, we can adjust the antigen retrieval very easily (low vs. high pH and the time).
