Fms-related tyrosine kinase 1 (FLT1/VEGFR1), recombinant human protein is supplied as a lyophilized powder. It is suitable for use in analysis of protein structure. In general, recombinant proteins can also be used as an immunogen, as a protein standard, or in cell biology research applications. Since this product is a truncated protein and does not contain intracellular catalytic activity domain, it is not suitable for use in enzyme activity studies.

  • 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 5-30ng/mL in the presence of 5ng/mL human VEGF165
  • Formulation: Lyophilized in PBS, pH 7.4, 5% Mannitol, 5% Trehalose, and 0.02% Tween-80
  • Reconstitution: Dissolve the protein in sterile double distilled water to a concentration of 0.2mg/mL or lower; aliquot and use as soon as possible

Shipping Condition: Room Temperature. This protein is manufactured by Sino Biological Inc.
