Description

ZAP70 serves as a critical tyrosine kinase in T cell receptor signaling, playing an essential role in T cell development, activation, and immune response regulation. This 70 kDa zeta chain-associated protein kinase transmits signals from the T cell receptor complex to downstream effectors, making it a key target for researchers investigating adaptive immunity, immunodeficiency disorders, and T cell-mediated diseases.

This recombinant monoclonal antibody, clone 10C11, offers the reproducibility and consistency that demanding immunological research requires. Produced using recombinant technology with a defined sequence, this antibody eliminates the lot-to-lot variability often encountered with traditional hybridoma-derived reagents. The result is reliable, reproducible data across extended studies and between laboratories, particularly valuable when tracking subtle changes in ZAP70 expression or localization during T cell activation events.

Validated for immunofluorescence and flow cytometry applications, this antibody provides flexibility for researchers examining ZAP70 in different experimental contexts. Immunofluorescence studies using MCF-7 cells demonstrate clear cytoplasmic staining patterns at dilutions of 1:50 to 1:200, enabling visualization of ZAP70 subcellular distribution. Flow cytometry validation in Jurkat cells, a well-established T cell model, confirms robust detection of intracellular ZAP70 with clear separation from isotype control, supporting quantitative analysis of ZAP70 expression levels across cell populations.

Supplied in a glycerol-containing buffer for optimal stability, this antibody arrives ready for immediate use in your immunological research. Whether investigating T cell signaling pathways, characterizing immunodeficiency conditions, or exploring ZAP70's role in lymphocyte development, this recombinant antibody delivers the performance and consistency your research demands.

Target Background

Function

Tyrosine kinase that plays an essential role in regulation of the adaptive immune response. Regulates motility, adhesion and cytokine expression of mature T-cells, as well as thymocyte development. Contributes also to the development and activation of primary B-lymphocytes. When antigen presenting cells (APC) activate T-cell receptor (TCR), a serie of phosphorylations lead to the recruitment of ZAP70 to the doubly phosphorylated TCR component CD247/CD3Z through ITAM motif at the plasma membrane. This recruitment serves to localization to the stimulated TCR and to relieve its autoinhibited conformation. Release of ZAP70 active conformation is further stabilized by phosphorylation mediated by LCK. Subsequently, ZAP70 phosphorylates at least 2 essential adapter proteins: LAT and LCP2. In turn, a large number of signaling molecules are recruited and ultimately lead to lymphokine production, T-cell proliferation and differentiation. Furthermore, ZAP70 controls cytoskeleton modifications, adhesion and mobility of T-lymphocytes, thus ensuring correct delivery of effectors to the APC. ZAP70 is also required for TCR-CD247/CD3Z internalization and degradation through interaction with the E3 ubiquitin-protein ligase CBL and adapter proteins SLA and SLA2. Thus, ZAP70 regulates both T-cell activation switch on and switch off by modulating TCR expression at the T-cell surface. During thymocyte development, ZAP70 promotes survival and cell-cycle progression of developing thymocytes before positive selection (when cells are still CD4/CD8 double negative). Additionally, ZAP70-dependent signaling pathway may also contribute to primary B-cells formation and activation through B-cell receptor (BCR).
