Human Phospho-STAT5A (Y694) PharmaGenie ELISA Kit (SBRS1990)

Assay Genie's Phospho-STAT5A (Y694) PharmaGenie ELISA Kit enables researchers to quantify tyrosine 694 phosphorylation of STAT5A, a key effector of the JAK/STAT cytokine signaling cascade. The assay is validated for human and mouse STAT5A and is intended for cell lysate and tissue lysate samples, supporting studies in hematopoietic signaling, leukemia biology, and immune cell activation pathways. Each microplate-format kit provides 96 assays with a colorimetric readout, allowing direct comparison of activated STAT5A between treated and untreated samples. Components should be refrigerated between uses to preserve antibody activity, and aliquoting is recommended to limit freeze-thaw cycles. The assay discriminates the phosphorylated Y694 form from total STAT5A, providing mechanistic insight into upstream JAK2 kinase activity.
