Re: [Histonet] No Ribbon

2017-04-11 Thread Elizabeth Chlipala via Histonet
I might get some individuals upset but we really need to watch what we do in 
the histology lab and how that effects the precision of our process.  When you 
breath on the block you are basically generating a thicker section, it's not a 
good practice to keep.  Trust me I used to do this in the past.  Thicker 
sections especially for IHC will generate a more intense stain, most 
individuals may think that that should not be an issue but it is - in the 
clinical setting especially when you are staining for therapeutic markers such 
as Her2 and PD-L1 - 510K cleared kits for these recommend specific section 
thickness settings and in the research setting if you are running any type of 
analysis on a batch of samples.  If your microtome is set at 4 microns and you 
are breathing on the block you are not cutting at 4 microns, you are cutting 
thicker than that and a thicker section will increase staining intensity and 
therefore alter the results.

Just my two cents.

Yes, +1 to Paula, also:
- I often found they are too sharp (!!) to ribbon so a gentle wipe (in the 
direction of the bevel) with a kimwipe helps
- Also 'huffing' slightly on the block will warm the paraffin and both smooth 
out the wrinkles as well as make the sections stick together

Hi,
the blades are packed with a tiny, bit of oil. This can cause you to not obtain 
a ribbon.
Try gently cleaning with xylene, followed by alcohol before sectioning. Paula

Yes, I use ice for my blocks and get them as cold as possible.  It is a
high profile blade holder.  The paraffin is good for embedding and
processing.  I was told to use a low angle for Statcut blades, but I will
try it at 10.
Thanks
