Anti-STAT5b (phospho Tyr699) Antibody [A2H6]

Phospho-specific detection of activated STAT5b is enabled by this mouse monoclonal antibody (A2H6), which selectively recognises STAT5b when phosphorylated at tyrosine 699. Produced by Antibodies.com as a primary antibody reagent for signal transduction research, the clone is supplied as 100 µg of lyophilised IgG2b from a murine host and is unconjugated for flexible downstream assay design. The reagent is listed for human STAT5b reactivity and ELISA workflows. Researchers investigating JAK-STAT pathways, cytokine-driven transcriptional responses (including growth hormone, prolactin, and interleukin signalling), and downstream gene regulation can use this reagent to monitor Tyr699 phosphorylation as a marker of STAT5b activation. The lyophilised format supports convenient reconstitution and long-term storage, while the unconjugated format allows direct conjugation or pairing with secondary detection reagents depending on the chosen immunoassay.
