Recombinant protein corresponding to human VEGF121.
MaxLight(TM)490 is a new Blue-Green photostable dye conjugate comparable to DyLight(TM)488, Alexa Fluor(TM)488 and offers better labeling efficiency, brighter imaging and increased immunodetection. Absorbance (491nm), Emission (515nm), Extinction Coefficient 73,000. The Flt gene family of receptor tyrosine kinases includes Flt-1, KDR/Flk-1, Flt-3, and Flt-4. They encode receptors for VEGF, characterized by seven Ig-loops within their extracellular domain and a split kinase domain within the cytoplasmic domain. VEGF is an important angiogenic factor of many solid tumors and is also involved in the differentiation of endothelial cells. Flt-1 (Fms- like tyrosine kinase, VEGF-R1) is expressed on endothelial cells and on the common precursors of endothelial and hematopoietic stem cells. KDR (Flk-1, VEGF-R2) is the principal receptor involved in VEGF signaling. KDR is expressed on endothelial cells and stimulates angiogenesis, but is also expressed on bone marrow cells, and is thought to play a role in driving the proliferation of most or all leukemic cells. Flt3 is a class III receptor tyrosine kinase that is closely related to c-Kit and c-Fms. It is expressed in primitive hematopoietic cells and its ligand exerts proliferative effects on these cells in co- operation with other cytokines. Flt3 is also expressed the placenta, testis, spleen, thymus, bone marrow, brain and in cerebellar Purkinje cells. The VEGF receptors stimulate the Ras-MAP kinase pathway, suggesting that it signals as a conventional receptor tyrosine kinase. Applications: Suitable for use in Immunohistochemistry. Other applications not tested. Recommended Dilutions: Immunohistochemistry (Paraffin): 1:50-1:500. Use standard deparaffinization techniques on tissue speciens. Preheat tissues using a citrate buffer, pH 6.0 and high heat epitope retrieval techniques. Note: Do not allow tissues to dry out during the staining procedure. Optimal dilutions to be determined by the researcher. Control: Pancrea, Kidney, Adenocarcinoma Storage and Stability: Store product at 4C in the dark. DO NOT FREEZE! Stable at 4C for 12 months after receipt as an undiluted liquid. Dilute required amount only prior to immediate use. Further dilutions can be made in assay buffer. Caution: MaxLight(TM)490 conjugates are sensitive to light. For maximum recovery of product, centrifuge the original vial prior to removing the cap. Note: Applications are based on unconjugated antibody.
