LAG3 Protein, Rat, Recombinant (His Tag)

• Background:

  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.

  Q5BK54

• Expression System:

  HEK293 Cells

• Tag:

  C-His

• Field of Research:

  Cancer Drug Targets

• Endotoxin:

  < 1.0 EU per μg of the protein as determined by the LAL method.

• Purity:

  > 90 % as determined by SDS-PAGE.

• Activity:

  Measured by its ability to bind FGL1 Protein, Mouse, Recombinant (hFc Tag) (Cat:PM53386M4) in functional ELISA.

• Form:

  Lyophilized

• Buffer:

  Lyophilized from sterile 20 mM NaAc, 500 mM NaCl, 10 % Glycerol, 0.02 % tween 20, pH 5.5. 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.

• Function:

  CD Molecule proteins, Cancer proteins, Receptor Proteins, Immunotherapy proteins, Immune Checkpoint Proteins, Biological Target proteins

• Molecular Weight:

  The recombinant rat LAG3 comprises 430 amino acids and predicts a molecular mass of 47.1 kDa. The apparent molecular mass of the recombinant protein is approximately 55 kDa in SDS-PAGE under reducing conditions due to glycosylation.

• Storage Conditions:

  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. Stable for 1 year at -20°C or below from date of shipment. For maximum recovery of product, centrifuge the original vial after thawing and opening the cap. For long-term storage, aliquot and store at -20°C or below. Avoid repeated freeze-thaw cycles.
