分子别名（Synonym）:CD267,CVID,CVID2,IGAD2,RYZN,TACI,TNFRSF14B

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 TNFRSF13B consists of 130 amino acids and has a predicted molecular mass of 14.8 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rhTNFRSF13B is approximately 18-24 kDa.

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

生物活性(Activity)：Measured by its ability to inhibit BAFF-mediated proliferation of mouse splenocytes. The ED50 for this effect is typically 0.6-3ng/mL in the presence of 2.5ng/mL BAFF.

表达区间（Protein Construction）：A DNA sequence encoding the human TNFRSF13B isoform 2 (O14836-2) extracellular domain (Ser 2-Thr 120) was expressed, with a polyhistidine tag at the C-terminus and a signal peptide at the N-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.
