STAT4 (pY693) Monoclonal / FITC / REA855

Product Details

Description	Clone REA855 recognizes the human signal transducer and activator of transcription 4 (STAT4) antigen phosphorylated at tyrosine 693 (pY693). STAT4 is a member of signal transducers and activators of the transcription (STAT) family. STAT proteins transmit signals from a receptor complex to the nucleus and activate gene expression. The seven STAT family members play a critical role in activation of signaling pathways in response to the presence of various cytokines and growth factors (interferon alpha (IFN-alpha), interferon gamma (IFN-gamma), EGF, PDGF, and interleukin 6 (IL-6)). STAT4 is involved in the development of Tʜ1 cells from naive CD4+ T cells and IFN-gamma production in response to IL-12. \| Additional information: Clone REA855 displays negligible binding to Fc receptors.

About FITC
Fluorescein isothiocyanate (FITC) has an excitation peak at 495 nm and an emission peak at 519 nm. The name FITC is a misnomer in that the isothiocyanate is a reactive form of this dye. Once FITC is conjugated to an antibody, it is simply Fluorescein conjugated. FITC is one of the most widely used dyes for fluorescent applications, therefore most instruments come standard with a 488 nm laser and FITC filter set up. FITC is commonly conjugated to secondary antibodies and used in applications such as flow cytometry, immunocytochemistry, and immunohistochemistry. FITC is relatively dim, sensitive to photobleaching and it is susceptible to changes is pH. There are better performing alternatives to FITC, like Vio®Bright 515, Alexa Fluor™ 488, iFluor® 488, CF®488A and DY-488. FITC is a long-time generic dye with no sole manufacturer or trademark.
