Will A03761-1 anti-TFIIIB90-1 antibody work on parafin embedded sections? If so, which fixation method do you recommend we use (PFA, paraformaldehyde, other)?

N. Mitchell

Verified customer

Asked: 2017-12-15


You can see on the product datasheet, A03761-1 anti-TFIIIB90-1 antibody as been validated 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.
