分子别名（Synonym）:GISP,REG-IV,RELP

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 human REG4 consists of 147 amino acids and predictes a molecular mass of 17.4 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rh REG4 is approximately 18 and 22 kDa due to different glycosylation.

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

生物活性(Activity)：Measured by the ability of the immobilized protein to support the proliferation of HCT-116 human colorectal carcinoma cells (ATCC: CCL-247) under low serum conditions.

表达区间（Protein Construction）：A DNA sequence encoding the human REG4 (NP_001152824.1) (Ser 2-Pro 158) was expressed, with a polyhistidine tag at the C-terminus.

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.
