Anti-STAT5B (Ab-731) Antibody

Produced in rabbit as a polyclonal reagent and supplied as 100 µl of unconjugated antiserum, this Antibodies.com primary antibody specifically recognizes STAT5B phosphorylated at tyrosine residue 731. Validated for Western blot (WB) and immunohistochemistry (IHC) applications on human and mouse samples, it supports investigation of cytokine-driven JAK-STAT signaling cascades, including downstream effects on hematopoiesis, immune cell differentiation, and oncogenic pathways where aberrant STAT5B activation contributes to disease progression. The unconjugated format allows flexible pairing with secondary detection reagents across fluorescence, chromogenic, and chemiluminescent readouts.
