Active Recombinant Human Flt1 protein, His-tagged

• Cat.No.: Flt1-0826H
• Product Overview: Active Recombinant Human Flt1 protein(P17948-1)(Met 1-Asn 756) was expressed in Human Cells, fused with a polyhistidine tag at the C-terminus.

Specification

• Species: Human
• Source: Human Cells
• Tag: His
• Protein Length: 1-756 aa
• Form: Lyophilized from sterile PBS, pH 7.4.
• Bio-activity: Measured by its ability to inhibit the VEGF-dependent proliferation of human umbilical vein endothelial cells (HUVEC) (Conn, G. et al.,1990, Proc. Natl. Acad. Sci. USA 87:1323.). The ED50 for this effect is typically 10-40 ng/mL in the presence of 10 ng/mL human VEGF165.
• Molecular Mass: The secreted recombinant human VEGFR1 consists of 741 amino acids with the predicted molecular mass of 83.7 kDa. As a result of glycosylation, rhVEGFR1 migrates as an approximately 110-120 kDa band in SDS-PAGE under reducing conditions.
• Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method.
• Purity: > 97 % as determined by SDS-PAGE
• Storage: Store it under sterile conditions at -20°C to -80°C upon receiving. Recommend to aliquot the protein into smaller quantities for optimal storage. Avoid repeated freeze-thaw cycles.
• 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°C before opening to recover the entire contents.
