Description
Product Usage Information
SignalFlex™ conjugates are produced using highly validated Cell Signaling Technology ® primary antibodies and conjugation methods that have been rigorously tested, ensuring high-quality conjugates and lot-to-lot consistency. These conjugates are quality control tested by size exclusion chromatography (SEC) to determine antibody integrity. However, they are not tested on specific assays. Optimal dilutions/concentrations should be determined by the end user. When performing flow cytometry, we recommend using an isotype control conjugate at the same concentration as the antibody conjugate.
Storage
Supplied in PBS (pH 7.2), less than 0.1% sodium azide, and 2 mg/mL BSA. Store at 4°C. Do not aliquot the antibody. Protect from light. Do not freeze.
Specificity / Sensitivity
NFAT1 (D43B1) XP
Species Reactivity: Human, Mouse
Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Gly87 of human NFAT1 protein.
Background
The NFAT (nuclear factor of activated T cells) family of proteins consists of NFAT1 (NFATc2 or NFATp), NFAT2 (NFATc1 or NFATc), NFAT3 (NFATc4), and NFAT4 (NFATc3 or NFATx). All members of this family are transcription factors with a Rel homology domain and regulate gene transcription in concert with AP-1 (Jun/Fos) to orchestrate an effective immune response (1,2). NFAT proteins are predominantly expressed in cells of the immune system, but are also expressed in skeletal muscle, keratinocytes, and adipocytes, regulating cell differentiation programs in these cells (3). In resting cells, NFAT proteins are heavily phosphorylated and localized in the cytoplasm. Increased intracellular calcium concentrations activate the calcium/calmodulin-dependent serine phosphatase calcineurin, which dephosphorylates NFAT proteins, resulting in their subsequent translocation to the nucleus (2). Termination of NFAT signaling occurs upon declining calcium concentrations and phosphorylation of NFAT by kinases such as GSK-3 or CK1 (3,4). Cyclosporin A and FK506 are immunosuppressive drugs that inhibit calcineurin and thus retain NFAT proteins in the cytoplasm (5).
