分子别名（Synonym）:PAPP-A2,PAPP-E,PAPPE,PLAC3

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 secreted recombinant human PAPPA2 consists of 1174 amino acids with the predicted molecular mass of 131 kDa. As a result of glycosylation, rhPAPPA2 migrates as an approximately 170-180 kDa band 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 human PAPPA2 mature form (NP_064714.2) corresponding to amino acid (Ser 234-Cys 1396) was expressed， with a carboxy-terminal polyhistidine tag.

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.
