VEGFR-3, also known as FLT4, is a member of the Tyr protein kinase family. The extracellular portion of VEGFR-3 contains 7 immunoglobulin (Ig)-like domains and the cytoplasmic portion contains a protein kinase domain. FLT4 regulates angiogenesis and lymphangiogenesis, its ligands are VEGF-C and D and its binding is mediated by the 2nd and 3rd Ig-like domains of FLT4. During fetal development VEGFR-3 is expressed on endothelial cells, however, in the adult mice, the vascular endothelial cells lose VEGFR-3 expression, but the lymphatic endothelium expresses it constitutively. In addition, VEGFR-3 expression can be induced in tumors with active angiogenesis.

Related FAQs

Does BioLegend test each LEAF™ antibody by functional assay?

No, BioLegend does not test LEAF™ antibodies by functional assays unless otherwise indicated. Due to the possible complexities and variations of uses of biofunctional antibodies in different assays and because of the large product portfolio, BioLegend does not currently perform functional assays as a routine QC for the antibodies. However, we do provide references in which the antibodies were used for functional assays and we do perform QC to verify the specificity and quality of the antibody based on our strict specification criteria.

Do you guarantee that your antibodies are totally pathogen free?

BioLegend does not test for pathogens in-house aside from the GoInVivo™ product line. However, upon request, this can be tested on a custom basis with an outside, independent laboratory.

Does BioLegend test each LEAF™ antibody for potential pathogens?

No, BioLegend does not test for pathogens in-house unless otherwise indicated.  However, we can recommend an outside vendor to perform this testing as needed.

Have you tested this LEAF™/Ultra-LEAF™ antibody for in vivo or in vitro applications?

We don't test our antibodies for in vivo or in vitro applications unless otherwise indicated. Depending on the product, the TDS may describe literature supporting usage of a particular product for bioassay. It may be best to further consult the literature to find clone specific information.
