Anti-STAT5a (Ab-780) Antibody

Produced in rabbit as a polyclonal reagent, this unconjugated primary antibody targets STAT5a, a member of the signal transducers and activators of transcription family that mediates cytokine and growth factor signaling. Provided by Antibodies.com in a 100 µl vial, it is validated for Western blot and immunohistochemistry workflows on human samples, supporting detection of endogenous STAT5a protein in cell lysates, tissue sections, and other biological specimens. The polyclonal format enables recognition of multiple epitopes on the STAT5a molecule, which can be advantageous for detecting low-abundance targets across experimental conditions. Researchers investigating JAK-STAT pathway signaling, mammary gland biology, hematopoietic regulation, and immune cell differentiation can pair the unconjugated reagent with HRP, fluorophore, or biotin labels according to their experimental design. Each preparation is characterized by the manufacturer to verify specificity for the STAT5a target in intended applications.
