Biotinylated Mouse PD-L1/B7-H1 Protein (Primary Amine Labeling)
Recombinant Biotinylated Mouse PD-L1/B7-H1 Protein (Primary Amine Labeling) is expressed from HEK293 with His tag at the C-Terminus.It contains Phe19-Thr238 [Accession | NP_068693].
The protein has a predicted MW of 25.9 kDa. Due to glycosylation, the protein migrates to 45-60 kDa based on Bis-Tris PAGE result.
> 95% as determined by Bis-Tris PAGE
> 95% as determined by HPLC
Less than 1EU per μg by the LAL method.
Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
-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.
Biotinylated Mouse PD-L1 on Bis-Tris PAGE under reduced condition. The purity is greater than 95%.
The purity of Biotinylated Mouse PD-L1 is greater than 95% as determined by SEC-HPLC.
Biotinylated Mouse PD-L1, His Tag captured on CM5 Chip via anti-his antibody can bind Mouse PD-1 , hFc Tag with an affinity constant of 0.31 μM as determined in SPR assay (Biacore T200).
B7-H1, also known as PD-L1 and CD274, is an approximately 65 kDa transmembrane glycoprotein in the B7 family of immune regulatory molecules. PD-L1 has been identified as the ligand for the immunoinhibitory receptor programmed death-1(PD1/PDCD1) and has been demonstrated to play a role in the regulation of immune responses and peripheral tolerance.
