Active Recombinant Cynomolgus LAG3 protein, Fc-tagged

• Cat.No.: LAG3-1829C
• Product Overview: Cynomolgus LAG-3 / CD223, Fc Tag is expressed from human 293 cells (HEK293). It contains AA Ala 18 - His 449 (Accession # XP_005570011.1).

Specification

• Species: Cynomolgus
• Source: HEK293
• Tag: Fc
• Protein Length: AA Ala 18 - His 449
• Description: Lymphocyte activation gene 3 protein (LAG3) is also known as CD antigen CD223 and protein FDC, which belongs to immunoglobulin (Ig) superfamily and contains 4 extracellular Ig-like domains. The LAG3 gene contains 8 exons. The sequence data, exon/intron organization, and chromosomal localization all indicate a close relationship of LAG3 to CD4. LAG3 /CD223 involved in lymphocyte activation. LAG3 /CD223 binds to HLA class-II antigens.
• Predicted N Terminal: Ala 18
• Form: Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 100 mM Glycine, pH7.5, 10% trehalose.
• Bio-activity: Immobilized Cynomolgus LAG-3, Fc Tag at 2 μg/mL (100 μL/well) can bind Anti-LAG3 MAb, Human IgG1 with a linear range of 1-51 ng/mL.
• Molecular Mass: This protein carries a human IgG1 Fc tag at the C-terminus. The protein has a calculated MW of 73.2 kDa. The protein migrates as 90-100 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
• Endotoxin: Less than 1.0 EU per μg by the LAL method.
• Purity: >80% as determined by SDS-PAGE.
• Storage: For long term storage, the product should be stored at lyophilized state at -20°C or lower. Please avoid repeated freeze-thaw cycles. No activity loss is observed after storage at: 4-8°C for 12 months in lyophilized state; -70°C for 3 months under sterile conditions after reconstitution.
• Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4℃ before opening to recover the entire contents.
