LAG3 (Lymphocyte Activating 3) is a Protein Coding gene. 2 alternatively spliced human isoforms have been reported. LAG3, also known as CD223 and Lymphocyte activation gene 3, belongs to the immunoglobulin (Ig) superfamily. The LAG3 gene contains 8 exons. It is selectively expressed in activated T and NK cells. LAG3 contains 4 extracellular Ig-like domains and has a negative regulatory function in T cells. It also acts as a new marker of T cell-induced B cell activation. As a soluble molecule, LAG3 activates antigen-presenting cells through MHC class II signaling, leading to increased antigen-specific T-cell responses in vivo. Diseases associated with LAG3 include Smoldering Myeloma and Kyphoscoliotic Heart Disease.Cancer ImmunotherapyCo-inhibitory Immune Checkpoint TargetsImmune CheckpointImmune Checkpoint TargetsImmunotherapyTargeted Therapy

Expression System | HEK293 |
Tag | hFc,AVI |
Accession Number | NP_002277.4 |
Synonyms | lymphocyte-activation gene 3, CD223, LAG-3 |
Construction | A DNA sequence encoding the Human LAG3 (NP_002277.4)(Met1-Leu450) was expressed with a c-terminal AVI tagged Fc region of human IgG1 at the C-terminus (Fc-AVI). The expressed protein was biotinylated in vivo by the Biotin-Protein ligase (BirA enzyme) which is co-expressed. |
Protein Purity | ≥ 90 % as determined by SDS-PAGE. ≥ 90 % as determined by SEC-HPLC. |
Molecular Weight | Approxiamtely 74.73 kDa |
Endotoxin | < 1.0 EU per μg protein as determined by the LAL method. |
Formulation | Lyophilized from sterile 20mM NaH2PO4, 150mM NaCl, 0. 1M Arg, 10% glycerol, 0. 01% tween20, pH 7.4. Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0. 01% Tween 80 are added as protectants before lyophilization. Please refer to the specific buffer information in the hard copy of CoA. |
Reconstitution | A hardcopy of datasheet with reconstitution instructions is sent along with the products. Please refer to it for detailed information. |
Stability & Storage |
Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃. Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles. |
Shipping |
In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise. |
