HLA-DRB1 Human

Data sheet

Formulation

HLA-DRB1 protein solution (1mg/ml) containing 20mM Tris-HCl buffer (pH 8.0), 0.4M Urea and 10% glycerol.

Purity

Greater than 85% as determined by SDS-PAGE.

Inactivation

Protein quantitation was carried out by two independent methods:1. UV spectroscopy at 280 nm using the absorbency value of 0.558 as the extinction coefficient for a 0.1% (1mg/ml) solution. This value is calculated by the PC GENE computer analysis program

Description

HLA-DRB1 Human Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 219 amino acids (30-227 a.a) and having a molecular mass of 25.2kDa.HLA-DRB1 is fused to a 21 amino acid His-tag at N-terminus & purified by proprieta

Protein Background

Major Histocompatibility Complex Class II DR Beta 1 also known as HLA-DRB1 ia a member of the HLA class II beta chain paralogs. Molecule class II is a heterodimer consisting of an alpha (DRA) and a beta chain (DRB), both anchored in the membrane. HLA-DRB1

Expression host

Escherichia Coli.
