Human CD1B & B2M Protein Product Information
Synonym:CD1B & B2M Heterodimer
Protein Construction:A DNA sequence encoding the extracellular domain (Met1-Ser303) of human CD1B (NP_001755.1) was fused with a polyhistidine tag at the C-terminus, constructed the plasmid 1; A DNA sequence encoding the human B2M (P61769) (Met1-Met119) constructed the plasmid 2. The two plasmids were co-expressed and the CD1B/B2M heterodimer was purified.
Species:Human
Expressed Host:Human Cells
Shipping:In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.
Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
Human CD1B & B2M Protein QC Testing
Purity:(70.1+28.3) % as determined by SDS-PAGE
Endotoxin:< 1.0 EU per μg of the protein as determined by the LAL method
Stability:Samples are stable for up to twelve months from date of receipt at -70℃
Predicted N Terminal:Ser 18 & Ile 21
Molecule Mass:The recombinant heterodimer of human CD1B/B2M comprises 397 (297+100) amino acids and has a calculated molecular mass of 44.7 (33.0+ 11.7) KDa. The apparent molecular mass of rh CD1B/B2M heterodimer is approximately 39.6 and 13.1 KDa respectively in SDS-PAGE under reducing conditions.
Formulation:Lyophilized from sterile PBS, pH 7.4.
1. Normally 5 % - 8 % trehalose and mannitol are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.
2. Please contact us for any concerns or special requirements.
Human CD1B & B2M Protein Usage Guide
