      Alexa Fluor® 488 Mouse anti-TIE2 (pY1102)
      Alexa Fluor® 488 Mouse anti-TIE2 (pY1102)
      Analysis of TIE2 (pY1102) in human vascular endothelium.  EA-hy 926 cells (Edgell, McDonald, Graham, 1983)) were serum starved overnight, detached using 1X trypsin, washed, resuspended in serum-free DMEM and rested for 20 minutes at 37°C, and then either left unstimulated (open histogram) or stimulated with 1 mM Pervanadate (Sigma Cat. No. S6508, shaded histogram) for 20 minutes at 37°C (left figure).  The cells were fixed (BD Cytofix™ buffer, Cat. No. 554655) for 10 minutes at 37°C, then permeabilized (BD Phosflow™ Perm Buffer III, Cat. No. 558050) on ice for at least 30 minutes, and then stained with Alexa Fluor® 488 Mouse anti-TIE2 (pY1102, Cat. No. 560053).  Flow cytometry was performed on a BD FACSCalibur™ flow cytometry system.  The specificity of mAb K93-754 was confirmed by western blot using unconjugated antibody, at 0.25, 0.125 and 0.063 μg/ml (lanes 1, 2, and 3, respectively) on lysates from control (left panel) and Pervanadate-treated (right panel) EA-hy 926 cells (right figure).  TIE2 (pY1102) is identified as a band of 160 kDa in the treated cells.

      1. This reagent has been pre-diluted for use at the recommended Volume per Test. We typically use 1 × 10^6 cells in a 100-µl experimental sample (a test).
      2. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
      3. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.

      K93-754

      TIE2 (Tyrosine kinase with Immunoglobulin-like and EGF-like domains 2), also known as TEK (Tunical Endothelial Kinase), is an endothelial and hematopoietic cell-specific receptor tyrosine kinase (RTK) that is critical to the development and maintenance of the vasculature and highly conserved among vertebrate species.  The angiopoietins are ligands of TIE2, and the abnormal vascular growth that often occurs in solid tumors is a result of disruptions in the coordinated actions of the angiopoietins, TIE2, and the closely related TIE1 RTK.  Upon activation by angiopoietins, TIE2 autophosphorylates at least 2 tyrosines in its protein kinase domain and at least 3 tyrosines in its C-terminal tail.  Phosphorylation at tyrosine 1102 (Y1102) leads to activation of the Akt signal transduction pathway, enhancing endothelial cell survival.  The phosphorylated Y1102 also recruits and activates the src homology 2 domain-containing adaptor proteins Grb2 and ShcA, affecting endothelial cell adhesion and motility.  

      The K93-754 monoclonal antibody recognizes the phosphorylated Y1102 in the C-terminal tail of activated TIE2.  The orthologous phosphorylation site in mouse TIE2 is Y1100.

      Alexa Fluor™ 488
      Alexa Fluor™ 488 Dye is part of the BD blue family of dyes. This is a small organic fluorochrome with an excitation maximum (Ex Max) at 494-nm and an emission maximum (Em Max) at 517-nm. Alexa Fluor™ 488 is designed to be excited by the Blue laser (488 nm) and detected using an optical filter centered near 520-nm (e.g., a 530/30-nm bandpass filter). Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
