Ab64857 is not guaranteed for WB with endogenous protein since Ab64857 has been batch tested in WB using recombinant full length FGF21 protein only and not all batches detect endogenous FGF21 protein in WB.
For endogenous FGR21, we recommend RabMAb ab171941 (Anti-FGF21 antibody [EPR8314(2)])
Batches of this product that have a concentration < 1mg/ml may have BSA added as a stabilising agent. If you would like information about the formulation of a specific lot, please contact our scientific support team who will be happy to help.
