Figure 2. Western blot analysis to demonstrate that anti-POU5F1 antibody identifies proteins of defined molecular weight in buffalo testes.

Figure 2

Protein lysates from prepubertal (4- to 6- month old; lane 1) and from adult (2- to 3- year old; lane 2) buffalo testes shows that POU5F1 protein exists in two isoforms; large (∼47 kDa) and small (∼21 kDa). BETA-ACTIN was used for normalizing protein samples.
