Recombinant Human NRP1 protein, His-tagged

• Cat.No.: NRP1-2065H
• Product Overview: Recombinant Human NRP1 (Phe22-Lys644) protein was fused to His-tag at C-terminus and expressed in human 293 cells (HEK293).

Specification

• Species: Human
• Source: HEK293
• Tag: His
• ProteinLength: Phe22-Lys644
• Description: Neuropilin-1 (NRP1) is also known as Vascular endothelial cell growth factor 165 receptor (VEGF165R), CD antigen CD304, which belongs to the neuropilin family. The membrane-bound isoform 1 is a receptor involved in the development of the cardiovascular system, in angiogenesis, in the formation of certain neuronal circuits and in organogenesis outside the nervous system. It mediates the chemorepulsant activity of semaphorins. It binds to semaphorin 3A, The PLGF-2 isoform of PGF, The VEGF-165 isoform of VEGF and VEGF-B. Coexpression with KDR results in increased VEGF-165 binding to KDR as well as increased chemotaxis. It may regulate VEGF-induced angiogenesis. The soluble isoform 2 binds VEGF-165 and appears to inhibit its binding to cells.
• Predicted N Terminal: Phe22
• Form: Lyophilized from 0.22 μm filtered solution in PBS, pH7.4, 10% trehalose.
• Molecular Mass: The protein has a calculated MW of 70.7 kDa. The protein migrates as 75-116 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
• Endotoxin: Less than 1.0 EU per μg by the LAL method.
• Purity: >92% as determined by SDS-PAGE.
• Storage: For long term storage, the product should be stored at lyophilized state at -20 centigrade or lower.
  Please avoid repeated freeze-thaw cycles.
  This product is stable after storage at:
  -20 to -70 centigrade for 12 months in lyophilized state;
  -70 centigrade for 3 months under sterile conditions after reconstitution.
• Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4℃ before opening to recover the entire contents.
