Spécificité

Clone 1F10 is a ZooMAb^® rabbit recombinant monoclonal antibody that specifically detects Tyrosine-protein kinase ZAP-70 phosphorylated on tyrosine 493.

Immunogène

KLH-conjugated linear peptide corresponding to 10 amino acids surrounding phosphotyrosine 493 from the C-terminal region of human Zap-70.

Application

Quality Control Testing

Western Blotting Analysis: A 1:25,000 dilution of this antibody detected Phospho-Zap-70 (Tyr 493) in lysate from C2C12 cells treated with 5 mM Pervanadate, but not in lysate from untreated cells .

Tested Applications

Immunocytochemistry Analysis: A 1:1,000 dilution from a representative lot detected Phospho-Zap-70 (Tyr493) in Jurkat cells treated with hydrogen peroxide (10 mM; 3 min.).

Flow Cytometry Analysis: 1 µg from a representative lot detected Phospho-Zap-70 (Tyr493) in one million Jurkat cells treated with hydrogen peroxide (10 mM).

Note: Actual optimal working dilutions must be determined by end user as specimens, and experimental conditions may vary with the end user.

Description de la cible

Tyrosine-protein kinase ZAP-70 (UniProt: P43403; also known as EC:2.7.10.2, 70 kDa zeta-chain associated protein, Syk-related tyrosine kinase) is encoded by the ZAP70 (also known as SRK) gene (Gene ID: 7535) in human. ZAP-70 is a tyrosine kinase that is expressed in T cells and NK cells and plays an essential role in regulation of the adaptive immune response. Its expression is also observed in early thymocytes and pro/pre-B-cells. It is involved in regulating motility, adhesion, and cytokine expression of mature T-cells and thymocyte development.  In quiescent T cells, it is cytoplasmic and upon TCR activation, it is recruited at the plasma membrane by interacting with CD247/CD3Z.  ZAP-70 contains two tandem SH2 domains (aa 10-102 and 163-254) that bind to the doubly phosphorylated tyrosine-based activation motif (ITAM) of CD247/CD3Z and the non-canonical phosphorylated tyrosine-based activation motif (TAM) of Ras Homolog Family Member H (RHOH). Its protein kinase domain is localized in amino acids 338-600. It has an interdomain B region (aa 255-337), located between the second SH2 and the kinase domain, contains 3 tyrosine residues (Tyr-292, 315, 319) that are phosphorylated following TCR activation. Phosphorylation of Tyr-315 and Tyr-319 is reported to be essential for ZAP70 positive function on T-lymphocyte activation, whereas Tyr-292 is shown to have a negative regulatory role. Within the protein kinase domain, Tyr-492 and Tyr-493 are also shown to be phosphorylated after TCR induction. Here Tyr-492 plays a negative regulatory role and Tyr-493 has a positive role and can be  dephosphorylated by protein tyrosine phosphatase non-receptor type 22 (PTN22). Aberrant high expression of ZAP-70 has been reported in a subset of Chronic Lymphocytic Leukemia (CLL) subjects and reflects an unfavorable clinical outcome. This ZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Forme physique

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS, 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 µL.

Reconstitution

0.3 mg/mL after reconstitution at 25 µL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

Stockage et stabilité

Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 µL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
