分子别名（Synonym）:B7,B7-1,B7.1,BB1,CD28LG,CD28LG1,LAB7

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 mature recombinant human B7-1 consists of 214 amino acids and predicts a molecular mass of 25.5 kDa. As a result of glycosylation, rhB7-1 migrates as approximately 45 kDa band in SDS-PAGE.

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

生物活性(Activity)：

表达区间（Protein Construction）：The mature form of human B7-1 (NP_005182.1) extracellular domain (Ser 2-Asn 242) with five amini acids (DDDDK) at the C-terminus was expressed and 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.
