Description de la cible

Lymphocyte activation gene 3 protein (UniProt: P18627; also known as LAG-3, CD223) is encoded by the LAG3 (also known as FDC) gene (Gene ID: 3902) in human. LAG3 is a single-pass type I membrane glycoprotein that is synthesized with a signal peptide (aa 1-22), which is subsequently cleaved off to generate the mature form that contains an extracellular domain (aa 23-450), a transmembrane domain (aa 451-471), and a cytoplasmic domain (aa 472-525). It contains three Ig-like C2-type domains and one Ig-like V-type domain. LAG3 is primarily expressed in activated T-cells and in a subset of natural killer cells. Its expression is induced by IL-2, IL-7, and IL-12 on activated T-cells. Almost all CD4+ cells expressing LAG3 also Express^™ CD25. However, only about 10% of CD4+ cells lacking LAG3 Express^™ CD25. LAG3 serves as an inhibitory receptor on antigen activated T-cells and delivers inhibitory signals upon binding to ligands. Fibrinogen-like protein 1 (FGL1) is shown to be a major ligand for LAG3. LAG3 is reported to suppresses homeostasis proliferation (HP^®) of CD4 and CD8 lymphocytes and some dendritic cell populations. Mice deficient in LAG3 display enhanced homeostasis proliferation (HP^®). Following TCR engagement, it is shown to associate with CD3-TCR in the immunological synapse and directly inhibits T-cell activation. LAG3 can be proteolytically cleaved by ADAM10 and ADAM17 within the connecting peptide region to generate a secretory form (sLAG3). ADAM10 is reported to mediate constitutive cleavage, but cleavage increases following T-cell activation. On the other hand, cleavage by ADAM17 is induced by TCR signaling in a Protein Kinase C theta (PRKCQ)-dependent manner. 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

300 µg/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.
