  • Work with LifeSpan to design a custom immunohistochemistry to address your specific biological question. Outsource the entire localization process without having to worry about finding and characterizing target specific antibodies, sourcing and validating difficult-to-find tissues, and having the ability to interpret the resulting immunostaining in relation to complex human pathologies.

  • TCR Screening Services

  • Test your therapeutic antibodies in immunohistochemistry against a broad panel of normal frozen human tissue types in order to determine potential unintended binding. Our non-GLP TCR services are designed on the FDA recommendation outlined in their "Points to Consider in the Manufacture and Testing of Monoclonal Antibody Products for Human Use".

Specificity and Use

KDR / VEGFR2 / FLK1 antibody was raised against a synthetic peptide made to a C-terminal region of the murine VEGFR2 protein sequence (between residues 1300-1367). [Swiss-Prot# P35918]
This has only been shown to recognize the native form (180-190 kD protein) of VEGFR-2, known as Flk-1 / KDR / VEGFR 2 (Vascular Endothelial Growth Factor Receptor 2), though it was raised against the precursor form.
Immunohistochemistry: LS-B669 was validated for use in immunohistochemistry on a panel of 21 formalin-fixed, paraffin-embedded (FFPE) human tissues after heat induced antigen retrieval in pH 6.0 citrate buffer. After incubation with the primary antibody, slides were incubated with biotinylated secondary antibody, followed by alkaline phosphatase-streptavidin and chromogen. The stained slides were evaluated by a pathologist to confirm staining specificity. The optimal working concentration for LS-B669 was determined to be 5 ug/ml.


Tris-citrate/phosphate buffer, pH 7-8 containing 0.1% sodium azide
Store at +4°C. DO NOT FREEZE.
For research use only.

Tyrosine-protein kinase that acts as a cell-surface receptor for VEGFA, VEGFC and VEGFD. Plays an essential role in the regulation of angiogenesis, vascular development, vascular permeability, and embryonic hematopoiesis. Promotes proliferation, survival, migration and differentiation of endothelial cells. Promotes reorganization of the actin cytoskeleton. Isoforms lacking a transmembrane domain, such as isoform 2 and isoform 3, may function as decoy receptors for VEGFA, VEGFC and/or VEGFD.
