3 Customer Q&As for Anti-Phospho TIF-IA (Ser649) Antibody


Does P05439 anti-Phospho TIF-IA (Ser649) antibody work on parafin embedded sections? If so, which fixation method do you recommend we use (PFA, paraformaldehyde, other)?

You can see on the product datasheet, P05439 anti-Phospho TIF-IA (Ser649) antibody as been tested on WB. It is best to use PFA for fixation because it has better tissue penetration ability. PFA needs to be prepared fresh before use. Long term stored PFA turns into formalin, as the PFA molecules congregate and become formalin.

We are currently using anti-Phospho TIF-IA (Ser649) antibody P05439 for human tissue, and we are happy with the WB results. The species of reactivity given in the datasheet says human. Is it true that the antibody can work on pig tissues as well?

The anti-Phospho TIF-IA (Ser649) antibody (P05439) has not been tested for cross reactivity specifically with pig tissues, but there is a good chance of cross reactivity. We have an innovator award program that if you test this antibody and show it works in pig you can get your next antibody for free. Please contact me if I can help you with anything.
