分子别名（Synonym）:CD89,CTB-61M7.2,FcalphaRI,FCAR,XXbac-BPG230H20.5

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 CD89 is a monomeric protein consisting of 217 amino acids and predicts a molecular mass of 25 kDa. The apparent molecular mass of rhCD89 is approximately 45-50 kDa in SDS-PAGE under reducing conditions.

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

生物活性(Activity)：Measured by its ability to bind human IgA in functional Elisa.

表达区间（Protein Construction）：A DNA sequence encoding the pro form of human FCAR extracellular domain (NP_001991.1) (Ser 2-Asn 227) was expressed with a C-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.
