分子别名（Synonym）:CD1B & B2M Heterodimer

种属（Species）：Human

表达系统（Expressed Host）：HEK293 Cells

产品状态（Buffer）：Lyophilized from sterile PBS, pH 7.4.

分子量（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.

内毒素（Endotoxin）：＜1.0 EU per μg by the LAL method.

生物活性(Activity)：

表达区间（Protein Construction）：A DNA sequence encoding the extracellular domain (Ser2-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) (Ser2-Ser219) constructed the plasmid 2. The two plasmids were co-expressed and the CD1B/B2M heterodimer was purified.

存储条件（Storage）： For long term storage, the product should be stored at lyophilized state at -20℃ or lower.Please avoid repeated freeze-thaw cycles. No activity loss is observed after storage at:4-8℃ for 12 months in lyophilized state;-70℃ for 3 months under sterile conditions after reconstitution.

运输条件： 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.
