What is the most suitable positive control for PD-1 for immuno immunocytochemical and immunohistochemical staining?
Simona hello,
Please, see pp.5&6 of this document:
https://www.accessdata.fda.gov/cdrh_docs/pdf15/p150013s001c.pdf
If the above is not viable - tonsil tissue:

A generally useful document:

I hope this helps :)
Valeria Tananska thank you very much :)
I don't do ICC, but for IHC you should have PD1 positive cells in samples of tonsil, or lymph node, which can be used as positive controls. Note that PD1 expression in tonsil lymphocytes tends to be quite strong, compared to in say tumour samples.
Instead of checking only the mRNA level, I want to check the active protein level of MMP-1 in Liver tissue from mice. How can I do that?
