The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Application notesIHC-P: 1/50 - 1/100. Perform heat mediated antigen retrieval via the microwave method before commencing with IHC staining protocol. Enzymatic antigen retrieval has also been attempted, however this was not as successful at the microwave method.
Not yet tested in other applications.
Optimal dilutions/concentrations should be determined by the end user.
FunctionTyrosine phosphatase which dephosphorylates or contributes to the dephosphorylation of CTNND1, PDGFRB, MET, RET (variant MEN2A), KDR, LYN, SRC, MAPK1, MAPK3, EGFR, TJP1, OCLN, PIK3R1 and PIK3R2. Plays a role in cell adhesion, migration, proliferation and differentiation. Involved in vascular development. Regulator of macrophage adhesion and spreading. Positively affects cell-matrix adhesion. Positive regulator of platelet activation and thrombosis. Negative regulator of cell proliferation. Negative regulator of PDGF-stimulated cell migration; through dephosphorylation of PDGFR. Positive regulator of endothelial cell survival, as well as of VEGF-induced SRC and AKT activation; through KDR dephosphorylation. Negative regulator of EGFR signaling pathway; through EGFR dephosphorylation. Enhances the barrier function of epithelial junctions during reassembly. Negatively regulates T-cell receptor (TCR) signaling. Upon T-cell TCR activation, it is up-regulated and excluded from the immunological synapses, while upon T-cell-antigen presenting cells (APC) disengagement, it is no longer excluded and can dephosphorylate PLCG1 and LAT to down-regulate prolongation of signaling.
Tissue specificityExpressed in the promyelocytic cell line HL60, the granulocyte-macrophage colony-stimulating factor-dependent leukemic cell line F-36P, and the interleukin-3 and erythropoietin-dependent leukemic cell line F-36E. Expressed predominantly in epithelial cells and lymphocytes. Enhanced expression at high cell density.
Sequence similaritiesBelongs to the protein-tyrosine phosphatase family. Receptor class 3 subfamily. Contains 9 fibronectin type-III domains. Contains 1 tyrosine-protein phosphatase domain.
Post-translational modificationsN- and O-glycosylated.
Cellular localizationCell membrane. Cell projection > ruffle membrane. Cell junction. After T cell stimulation, it is temporarily excluded from immunological synapses.
Liver carcinoma tissue was fixed in 10% formalin at 4°C overnight and paraffin embedded. Following blocking the tissue sections were incubated with ab10639 (1/100 dilution) at 37°C for 1 hour, and with the secondary antibody at 37°C for 30 minutes. The slides were counterstained with Hematoxylin. Washes were carried out using TBS. Heat mediated antigen retrieval was carried out using the Microwave method before commencing the staining protocol.
ab10639 is clearly localised to the cytoplasm of the tissue (brown). Nuclear staining can be seen in blue. 100x magnification.
