VEGF-C152S is a point mutant generated by the replacement of the second conserved Cys residue of the recombinant processed VEGF-C by a Ser residue. VEGF-C152S is analog to the human VEGF-C156S mutant and only active toward VEGFR-3/FLT -4 but, unlike wild type VEGF-C, is unable to bind to and to activate signalling through VEGFR-2/KDR. VEGF-C152S was inactive in the vascular permeability assay and did not increase migration of the capillary endothelial cells, indicating that these VEGF-like effects of VEGF-C require VEGFR-2 binding. Recombinant rat VEGF-C152 contains 152 amino acids residues and was fused to a His-tag (6x His) at the C-terminal end. As a result of glycosylation VEGF-C migrates as an 18-24 kDa protein in SDS-PAGE under reducing conditions.
Rat Vegfc expressed in Sf9-insect cells
CAT# CSC-CTK0844-10 (10 μg); CAT# CSC-CTK0844-50 (50 μg)
Greater than 90% as determined by SDS-PAGE.
Measured by its ability to stimulate phosphorylation of the VEGFR-3/FLT-4 receptor in porcine aortic endothelial cells (PAE/FLT -4 cells). The ED50 for this effect is typically 150-300 ng/ml corresponding to a specific activity of 5 x 10^3 Units/mg.
Less than 1 EU/μg.
Sterile-filtered white, lyophilized (freeze-dried) powder. The protein was lyophilized from a concentrated (1 mg/ml) solution with BSA.
Please centrifuge product briefly before opening vial. The lyophilized protein should be reconstituted in sterile PBS or medium to a concentration of 0,1 - 1,0 mg/ml. This solution can then be diluted into other aqueous buffers and stored at -20°C for future use.
Storage & Stability
The lyophilized protein, though stable at room temperature for up to 3 weeks, is best stored desiccated at -20°C. Reconstituted rRa VEGF-C152S should be used immediately or stored long- term in undiluted working aliquots at -20°C. Avoid repeated freeze-thaw cycles.
