Immunofluorescent analysis of Phospho-Zap70 pTyr315/319 in Jurkat cells treated with H2O2 (top right, bottom) or untreated (top left) using a Phospho-Zap70 pTyr315/319 recombinant rabbit monoclonal antibody (Product # 700177) at a dilution of 2ug/ml followed by detection using an Alexa Fluor 488-conjugated goat anti-rabbit secondary antibody at a dilution of 1:1000 and nuclei stained using Hoescht (blue). Pre-incubation of treated cells with phosphopeptide immunogen decreased signal (bottom right) while pre-incubation with non-phosphopeptide did not (bottom right).

ABfinity™ recombinant antibodies are rabbit monoclonal antibodies, unmatched for producing superior results. ABfinity™ antibodies are developed by immunizing animals, screening for functionality, cloning the immunogen-specific antibody genes into high-level mammalian expression vectors, produced on a large scale, and purified with Protein A.
ABfinity™ monoclonal antibodies resemble rabbit monoclonals isolated from serum or produced by hybridomas, but demonstrate greater specificity and sensitivity. Because ABfinity™ recombinant antibodies are derived from cloned DNA sequences of the heavy and light antibody chains, they are not susceptible to cell-line drift or lot-to-lot variation, thus allowing for peak specificity and performance.
Intact IgG appears on a non-reducing gel as ~150 kDa band and upon reduction generating a ~25 kDa light chain band and a ~50 kDa heavy chain.
Zeta-associated protein (ZAP-70), a 70 kDa member of the Syk tyrosine kinase family, plays a central role in lymphocyte activation and development, and is implicated in several immune disorders. Upon T-cell antigen receptor. Phosphorylation of both tyrosines 315. Phosphorylation of tyrosines 315 and 319 plays an important role in mediating the positive and negative selection of T cells in thymus. TLR9-activated B-cells display elevated ZAP-70 expression levels which correlate with sustained PKB induction. Additionally,, a major catechin found in green tea, binds directly to ZAP-70 resulting in caspase-mediated apoptosis in Jurkat cells.
