Recombinant Human KDR, C13&N15-labeled

• Cat.No.: KDR-240H
• Product Overview: Recombinant Human VEGFR2 /KDR MS Standard Protein, C13 and N15-labeled (VEGFR2 / KDR, Heavy Labeled) Met 1 - Glu 764 (Accession # AAI31823) was produced in human 293 cells (HEK293).

Specification

• Description: Kinase insert domain receptor (KDR) also known as CD309, FLK1, VEGFR, VEGFR2, and is one of the subtypes of VEGFR. VEGF receptors are receptors for vascular endothelial growth factor (VEGF). There are three main subtypes of VEGFR, numbered 1, 2 and 3. The VEGF receptors have an extracellular portion consisting of 7 immunoglobulin-like domains, a single transmembrane spanning region and an intracellular portion containing a split tyrosine-kinase domain. VEGF-A binds to VEGFR-1 (Flt-1) and VEGFR-2 (KDR/Flk-1). VEGFR-2 appears to mediate almost all of the known cellular responses to VEGF.The function of VEGFR-1 is less well defined, although it is thought to modulate VEGFR-2 signaling. Another function of VEGFR-1 may be to act as a dummy/decoy receptor, sequestering VEGF from VEGFR-2 binding (this appears to be particularly important during vasculogenesis in the embryo).[1-3] In addition, VEGFR2 is able to interact with HIV-1 extracellular Tat protein upon VEGF activation, and seems to enhance angiogenesis in Kaposi"s sarcoma lesions.
• Source: HEK293
• Species: Human
• Form: Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally Mannitol or Trehalose are added as protectants before lyophilization.
• Molecular Mass: VEGFR2 / KDR, Heavy Labeled, fused with 6×His tag at the C-terminus, has a calculated MW of 86.2 kDa. The predicted N-terminus is Met 1. DTT-reduced Protein migrates as 100-110 kDa due to glycosylation.
• Endotoxin: Less than 1.0 EU per μg of the VEGFR2 / KDR, Heavy Labeled by the LAL method.
• Purity: >95% as determined by SDS-PAGE.
• Storage: Avoid repeated freeze-thaw cycles.No activity loss was observed after storage at:In lyophilized state for 1 year (4oC-8oC); After reconstitution under sterile conditions for 1 month (4oC-8oC) or 3 months (-20oC to -70oC).
