Gln 73 - Met 232

A DNA sequence encoding the extracellular domain (Gln 73-Met 232) of human CD74 isoform b (NP_004346.1) was fused with a polyhistidine tag at the N-terminus.

> 80 % as determined by SDS-PAGE

Measured by its binding ability in a functional ELISA. Immobilized human CD74 at 5 μg/ml (100 μl/well) can bind biotinylated human CTSL1 with a linear range of 3.2-400 ng/ml.

The recombinant human CD74 consists of 176 amino acids and has a calculated molecular mass of 20.4 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rhCD74 is approximately 34 kDa due to glycosylation.

HLA class II histocompatibility antigen gamma chain

Plays a critical role in MHC class II antigen processing by stabilizing peptide-free class II alpha/beta heterodimers in a complex soon after their synthesis and directing transport of the complex from the endoplasmic reticulum to the endosomal/lysosomal system where the antigen processing and binding of antigenic peptides to MHC class II takes place. Serves as cell surface receptor for the cytokine MIF.

Lyophilized from sterile PBS, pH 7.4
1. 5 % trehalose and mannitol are added as protectants before lyophilization.
2. Please contact us for any concerns or special requirements.

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

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.
