Product introduction

Recombinant Human CD37 Protein is expressed in HEK293 cells with an hFc (IgG1) tag at the N-terminus. It contains amino acid residues Ala113-Asn240 (UniProt accession: P11049-1).

Product details

Molecular aliases: Tetraspanin-26; Tspan-26; CD37; CD37 molecule; GP52-40; MGC120234;Tspan26
Protein length: Ala113-Asn240
Expression system: HEK293
Molecular weight: The protein has a predicted MW of 41.9 kDa. Due to glycosylation, the protein migrates to 50-60 kDa based on Bis-Tris PAGE result.
Purity: > 95% as determined by Bis-Tris PAGE > 95% as determined by HPLC
Endotoxin: Less than 1 EU per μg by the LAL method.
Formulation: Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
State: Lyophilized
Storage: -20 to -80°C for 12 months as supplied from date of receipt. -80°C for 3 months after reconstitution. Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
Reconstitution: Dissolve the lyophilized protein in distilled water. Please refer to the Certificate of Analysis for detailed instructions.

Bis-Tris PAGE Data — Human CD37 on Bis-Tris PAGE under reduced condition. The purity is greater than 95%.

SEC-HPLC Data — The purity of Human CD37 is greater than 95% as determined by SEC-HPLC.

Background

CD37 is a tetraspanin expressed prominently on the surface of B cells. It is an attractive molecular target exploited in the immunotherapy of B cell-derived lymphomas and leukemia. Currently, several monoclonal antibodies targeting CD37 as well as chimeric antigen receptor-based immunotherapies are being developed and investigated in clinical trials. Given the unique role of CD37 in the biology of B cells, it seems that CD37 constitutes more than a docking point for monoclonal antibodies, and targeting this molecule may provide additional benefit to relapsed or refractory patients.
