Immunizing Peptide (Blocking)
Our Abpromise guarantee covers the use of ab39256 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|IHC-FoFr||Use at an assay dependent concentration.|
|IHC-P||1/250. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.|
|WB||Use a concentration of 1 µg/ml. Detects a band of approximately 220 kDa (predicted molecular weight: 152 kDa).Can be blocked with Human VEGF Receptor 2 peptide (ab39255).|
FunctionReceptor for VEGF or VEGFC. Has a tyrosine-protein kinase activity. The VEGF-kinase ligand/receptor signaling system plays a key role in vascular development and regulation of vascular permeability. In case of HIV-1 infection, the interaction with extracellular viral Tat protein seems to enhance angiogenesis in Kaposi's sarcoma lesions.
Involvement in diseaseDefects in KDR are associated with susceptibility to hemangioma capillary infantile (HCI) [MIM:602089]. HCI are benign, highly proliferative lesions involving aberrant localized growth of capillary endothelium. They are the most common tumor of infancy, occurring in up to 10% of all births. Hemangiomas tend to appear shortly after birth and show rapid neonatal growth for up to 12 months characterized by endothelial hypercellularity and increased numbers of mast cells. This phase is followed by slow involution at a rate of about 10% per year and replacement by fibrofatty stroma.
Sequence similaritiesBelongs to the protein kinase superfamily. Tyr protein kinase family. CSF-1/PDGF receptor subfamily.
Contains 7 Ig-like C2-type (immunoglobulin-like) domains.

Goat Anti-Rabbit IgG H&L (HRP) preadsorbed (ab97080) at 1/5000 dilution
Predicted band size: 152 kDa
Observed band size: 220,230 kDa why is the actual band size different from the predicted?
Additional bands at: 31 kDa. We are unsure as to the identity of these extra bands.
ab39256 staining VEGF Receptor 2 in Human breast carcinoma tissue sections by IHC-P (Formaldehyde-fixed, paraffin-embedded sections). Tissue was fixed with formaldehyde and blocked with 5 minutes of peroxidase block followed by 10 minutes of protein block at 20°C; antigen retrieval was heat mediated in retrieval solution. Samples were incubated with primary antibody (1/250 in antibody diluent) for 45 minutes at 20°C. An undiluted HRP-conjugated polymer goat anti-mouse/rabbit IgG polyclonal polymer was used as secondary antibody.
ab39256 staining VEGF Receptor 2 in rat heart tissue section by Immunohistochemistry (PFA perfusion fixed frozen sections). Tissue underwent fixation with 4% PFA and it was later postfixed overnight in the same fixative. It was then cryoprotected in 30% sucrose and cut using a cryostat. The primary antibody was diluted 1/100 and incubated with sample for 18 hours at 20°C in PBS + 0.3 % Triton X100. An Alexa Fluor® 488 - conjugated goat polyclonal to rabbit IgG was used at dilution at 1/1000 as secondary antibody.
