蛋白结构(Molecular Characterization)

LAG-3 Structure

This protein carries a mouse IgG1 Fc tag at the C-terminus.

The protein has a calculated MW of 75.4 kDa. The protein migrates as 100 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

标记(Labeling)

Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.

蛋白标记度(Protein Ratio)

Passed as determined by the HABA assay / binding ELISA.

内毒素(Endotoxin)

Less than 1.0 EU per μg by the LAL method.

纯度(Purity)

>95% as determined by SDS-PAGE.

>90% as determined by SEC-MALS.

制剂(Formulation)

Lyophilized from 0.22 μm filtered solution in Tris with Glycine, Arginine and NaCl, pH7.5 with trehalose as protectant.

Report

 

活性(Bioactivity)-ELISA

LAG-3 ELISA

Immobilized Madarex LAG-3 MAb, Human IgG1 at 2 μg/mL (100 μL/well) can bind Biotinylated Human LAG-3, Mouse IgG2a Fc,Avitag (Cat. No. LA3-H82F3) with a linear range of 0.4-13 ng/mL (QC tested).

Protocol

 

活性(Bioactivity)-FACS

LAG-3 FACS

Flow Cytometry assay shows that Biotinylated Human LAG-3, Mouse IgG2a Fc,Avitag (Cat. No. LA3-H82F3) can bind to daudi cell surface. The concentration of LAG-3 used is 0.3 μg/mL (Routinely tested).

Protocol

 

背景(Background)

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.
