[Histonet] Need a procedure

[John Garratt]

Hi Terri, I suggest you use Histogel for block preparation. It works exceptionally well, it is good for IHC and does not have the pitfalls of plasma/thrombin.
Plasma/thrombin does work well for cell blocks but you will have to consider an ethical and safe source for your plasma.
The instructions for using Histogel are in the package insert though I have one comment. Be careful how you warm the Histogel and use a heat block. Do NOT use a microwave since there is a tendency to overheat the gel and you will end up with poor quality IHC.
