分子别名（Synonym）:BDCA4,CD304,Neuropilin-1,NP1,NRP,VEGF165R

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 NRP1 consists of 634 amino acids and has a calculated molecular mass of 71.3 kDa. As a result of glycosylation, rh NRP1 migrates as an approximately 88 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)：Using the Octet RED System, the affinity constant (Kd) of NRP1-his bound to biotinylated human VEGF165 was 25nM.

表达区间（Protein Construction）：A DNA sequence encoding the human NRP1 isoform b (NP_001019799.1) (Ser 2-Lys 644) was fused 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.
