Detection of Mouse Phospho-Tie-2 (Y992) antibody by Western Blot.

Detection of Mouse Phospho-Tie‑2 (Y992) by Western Blot.

Western blot shows lysates of NIH-3T3 mouse embryonic fibroblast cell line transfected with mouse Tie-2 and untreated (-) or treated (+) with 600 ng/mL Recombinant Human Angiopoietin-1 (Catalog # 923-AN) for 5 minutes. PVDF membrane was probed with 0.5 µg/mL of Rabbit Anti-Human/Mouse Phospho-Tie-2 (Y992) Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2720) followed by HRP-conjugated Anti-Rabbit IgG Secondary Antibody (Catalog # HAF008). A specific band was detected for Phospho-Tie-2 (Y992) at approximately 150 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
Phospho-Tie-2 (Y992) antibody in Human Kidney Tissue by Immunohistochemistry (IHC-P).

Phospho-Tie-2 (Y992) in Human Kidney Tissue.

Tie-2 was detected in immersion fixed paraffin-embedded sections of human kidney tissue using Rabbit Anti-Human/Mouse Phospho-Tie-2 (Y992) Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2720) at 1 µg/mL overnight at 4 °C. Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (Catalog # CTS013). Tissue was stained using the Anti-Rabbit IgG VisUCyte™ HRP Polymer Antibody (brown; Catalog # VC003) and counterstained with hematoxylin (blue). Specific staining was localized to cytoplasm in convoluted tubules. View our protocol for IHC Staining with VisUCyte HRP Polymer Detection Reagents.

Detection of Tie‑2 in HUVEC Human Cells by Flow Cytometry.

HUVEC human umbilical vein endothelial cells were unstimulated (light orange filled histogram) or treated with 100 µM pervanadate for 15 minutes (dark orange filled histogram), then stained with Human/Mouse Phospho- Tie-2 (Y992) Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2720) or control antibody (Catalog # AB-105-C, open histogram), followed by Phycoerythrin-conjugated Anti-Rabbit IgG Secondary Antibody (Catalog # F0110). To facilitate intracellular staining, cells were fixed with paraformaldehyde and permeabilized with methanol.

Background: Tie-2

Tie-2 (also known as TEK) is an angiogenic receptor tyrosine kinase required for the later stage of blood vessel maturation. Ligand binding induces receptor dimerization and autophosphorylation on multiple tyrosine residues. Y992 is located on the putative activation loop of Tie-2 and is a major autophosphorylation site.

Long Name

    After trying several pTIE2 Y992 antibodies I have realized that this antibody works on HUVEC and its variant cells. It would usually give some other bands, but the top upper band at around 160 kDa usually corresponds to pTIE2 on my HUVEC/L914F cells.

    Immunofluorescence with phospho Tie2
    Postnatal mouse cerebellum at P14 was used to determine the levels of phospho-Tie2 in the blood vessels. The blocking buffer and the antibody buffers were prepared in 0.2% gelatin in PBST (In primary and secondary solutions were used 0.025% of Saponin was added). The sections were antigen retrieved by boiling in a microwave for 5 min using 10mM Sodium citrate (pH6).
