Active Recombinant Human KDR Protein, Fc-tagged, Alexa Fluor 555 conjugated

• Cat.No.: KDR-5442HAF555
• Product Overview: Alexa Fluor 555 conjugated recombinant human KDRwas fused with the Fc part of human IgG1. The recombinant mature KDRis a disulfide-linked homodimeric protein. The KDR monomers have a mass ofapproximately 160 kDa.

Specification

• Species: Human
• Source: Insect Cells
• Tag: Fc
• Description: KDR has a lower affinity for VEGF than theFlt-1 receptor, but a higher signaling activity. Mitogenic activity inendothelial cells is mainly mediated by KDR leading to their proliferation.Differential splicing of the flt-1 gene leads to the formation of a secreted,soluble variant of VEGFR-1 (sVEGFR-1). No naturally occurring, secreted formsof KDR have so far been reported. The binding of VEGF165 to KDR is dependenton heparin.
• Form: Lyophilized
• Bio-activity: The activity of KDR was determined by its ability to inhibit the VEGF-dependent proliferation of human umbilical vein endothelial cells. The ED50 for this effectis typically 10-30 ng/mL.
• Molecular Mass: 160 kDa
• Endotoxin: < 0.1 ng/ μg of KDR
• Purity: > 90 % by SDS-PAGE and analyzed by silver stain
• Characteristic: Disulfide-linked homodimer
  Labeled with Alexa Fluor 555 via amines
  With an excitation and emission maximum of 555/565 nm, Alexa Fluor 555 can be efficiently excited using a 543 nm He-Ne laser line and detected under standard TRITC/Cy3 filters.
• Storage: Lyophilizedsamples are stable for greater than six months at -20 to -70 centigrade. Reconstituted KDR should be stored in working aliquots at -20 centigrade. Avoidrepeated freeze-thaw cycles.
• Reconstitution: The lyophilized KDRis soluble in water and most aqueous buffers. The lyophilized KDR should bereconstituted in PBS or medium to a concentration not lower than 50 μg/mL.
• Conjugation: Alexa Fluor 555
