Anti-STAT5A Antibody

Antibodies.com offers a rabbit polyclonal antibody raised against STAT5A, a member of the signal transducer and activator of transcription family that mediates cytokine and growth factor signaling through the JAK-STAT pathway. The unconjugated IgG reagent is supplied in a 200 µl vial and is validated for Western blot and immunohistochemistry applications on human and mouse samples.

STAT5A plays a central role in prolactin receptor signaling, T-cell development, and hematopoietic cell responses, making this polyclonal reagent useful for researchers investigating cytokine-driven transcriptional regulation, immune cell signaling, or mammary epithelial differentiation. The antibody recognizes the native STAT5A protein, supporting studies of ligand-induced activation kinetics and downstream gene expression in cell lysates or fixed tissue sections. Short-term handling at 4 °C is appropriate for working aliquots, while longer-term storage of frozen stock preserves reagent stability for repeated experimental use.
