Product details:
ab126429 is a very rapid, convenient and sensitive assay kit that can monitor the activation or function of important biological pathways in cells. It can be used for measuring the relative amount of STAT5 (Tyr694) phosphorylation and screening the effects of various treatments, inhibitors (such as siRNA or chemicals), or activators in cultured human cell lines. By determining STAT5 protein phosphorylation in your experimental model system, you can verify pathway activation in your cell lines without spending excess time and effort in preparing cell lysate and performing an analysis of Western Blot.
In the In-Cell STAT5 (Tyr694) ELISA kit, cells are seeded into a 96 well tissue culture plate. The cells are fixed after various treatments, inhibitors or activators. After blocking, Anti Phospho-STAT5 (Tyr694) or Anti-STAT5 (primary antibody) is pipetted into the wells and incubated. The wells are washed, and HRP-conjugated anti-mouse IgG (secondary antibody) is added to the wells. The wells are washed again, a TMB substrate solution is added to the wells and color develops in proportion to the amount of protein. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.

Signal Transducer and Activator of Transcription 5 commonly known as STAT5 is a member of the STAT protein family. It weighs approximately 94 kDa. STAT5 usually exists in two closely related forms STAT5a and STAT5b with both playing similar roles but having slightly different activity. This protein is widely expressed found in cells like lymphocytes epithelial cells and endothelial cells indicating its importance in various tissues.
Biological function summary
STAT5 acts as a transcription factor that modulates gene expression by binding to specific DNA sequences. It often forms part of a larger complex when activated. This complex relocation to the nucleus triggers transcriptional activities essential for cell growth differentiation and survival. As it interacts with other proteins STAT5 plays an important role in cytokine signaling particularly in response to interleukins and growth hormones.
Pathways
STAT5 is important in the JAK-STAT signaling pathway. This pathway is activated by cytokines and growth factors leading to STAT5 phosphorylation and its subsequent translocation into the nucleus. The interaction with Janus kinases (JAKs) facilitates this process. STAT5 also plays a significant role in the MAPK pathway linking it to various cellular responses and functions.
STAT5 has a strong association with oncological conditions like leukemia and lymphomas. Aberrant activation or dysregulation of STAT5 can lead to uncontrolled cell proliferation and survival contributing to cancer. Furthermore STAT5 is linked with autoimmune diseases with its malfunction affecting immune response and leading to disorders. In these conditions proteins like BCL-XL often interact with STAT5 influencing cell survival pathways.
