• Target description: Lymphocyte activation gene 3 protein (UniProt: Q61790; LAG-3, Activation-induced cytidine deaminase-linked autoimmunity protein, Aida, CD223) is encoded by the Lag3 gene (Gene ID: 16768) in murine species. LAG3 is a single-pass type I membrane glycoprotein that is synthesized with a signal peptide (aa 1-23), which is subsequently cleaved off to generate the mature form that contains an extracellular domain (aa 24-442), a transmembrane domain (aa 443-463), and a cytoplasmic domain (aa 464-521). It contains three Ig-like C2-type domains and one Ig-like V-type domain. LAG3 is primarily expressed in activated CD4+ and CD8+ T-cells. Its expression is also observed in a subset of regulatory T cells. It serves as an inhibitory receptor on antigen activated T-cells  and deliver inhibitory signals upon binding to ligands, such as Fibrinogen-like protein 1 (FGL1). It can negatively regulate the proliferation, activation, effector function and homeostasis of both CD8+ and CD4+ T-cells. Following TCR engagement, it associates 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.

• Physical form: 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.
• Storage and Stability: 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.
