Anti-LAT Antibody, clone 2B4 ZooMAb^® Rabbit Monoclonal

ZooMAb^® antibodies represent an entirely new generation of recombinant monoclonal antibodies. Each ZooMAb^® antibody is manufactured using our proprietary recombinant expression system, purified to homogeneity, and precisely dispensed to produce robust and highly reproducible lot-to-lot consistency. Only top-performing clones are released for use by researchers. Each antibody is validated for high specificity and affinity across multiple applications, including its most commonly used application. ZooMAb^® antibodies are reliably available and ready to ship when you need them.

Clone 2B4 is a ZooMAb^® Rabbit recombinant monoclonal antibody that specifically detects Linker for activation of T-cells family member 1 (LAT). It targets an epitope within 18 amino acids from the N-terminal half.

KLH-conjugated linear peptide corresponding to 18 amino acids from the N-terminal half of human Linker for activation of T-cells family member 1 (LAT).

Linker for activation of T-cells family member 1 (UniProt: O43561; also known as 36 kDa phospho-tyrosine adapter protein, pp36, p36-3, LAT) is encoded by the LAT gene (Gene ID: 27040) in human. LAT is a single-pass type III membrane protein with a short extracellular domain (aa 1-4), a transmembrane domain (aa 5-27), and a cytoplasmic domain (aa 28-262). It is expressed in thymus, T-cells, NK cells, and mast cells. It is required for T-cell antigen receptor (TCR)- and pre-TCR-mediated signaling, both in mature T-cells and during their development. It is also involved in low affinity immunoglobulin gamma Fc region receptor III (FCGR3)-mediated signaling in natural killer cells and in high affinity immunoglobulin epsilon receptor (FCER1)-mediated signaling in mast cells. It couples activation of these receptors and their associated kinases with distal intracellular events such as mobilization of intracellular calcium stores, protein kinase C activation, MAPK activation, and cytoskeletal reorganization. LAT undergoes phosphorylation on its tyrosine residues by ZAP70 upon TCR activation. It is one of the most prominently tyrosine-phosphorylated proteins detected following TCR engagement. Palmitoylation of Cys-26 and Cys-29 shown to be essential for its raft targeting and efficient phosphorylation. Phosphorylated form is shown to interacts directly with the regulatory subunit of phosphoinositide 3-kinase and the SH2 domains of GRB2, GRAP, GRAP2, PLC 1 and PLC 2. Mutations in LAT gene have been linked to immunodeficiency 52, an autosomal recessive disorder that is characterized by T-cell abnormalities, resulting in severe combined immunodeficiency and recurrent infections from infancy. Five isoforms of LAT have been described that are produced by alternative splicing. This ZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

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.

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.

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.
