Anti-STAT5b (phospho Tyr699) Antibody [A4B9]

Generated by Antibodies.com, this murine monoclonal reagent recognises STAT5b when phosphorylated at its activating tyrosine residue, providing a defined tool for monitoring cytokine-driven JAK-STAT signalling in human lymphocytes and other cell types.

Produced in mouse hosts as an IgG1 isotype, the unconjugated primary antibody is supplied as a 100 µg lyophilised powder that reconstitutes cleanly in standard aqueous buffers.

Each vial is validated for ELISA workflows, supporting quantification of phospho-STAT5b in cell-derived lysates and studies of pathway activation.

The lyophilised preparation enables long shelf life before reconstitution; once diluted, the antibody should be aliquoted, stored refrigerated, and protected from light, with minimal freeze-thaw exposure to preserve binding activity.

Intended for research use only, the reagent provides a phospho-specific detection option for in vitro experimental systems.
