Biological Information

Background Information:

The TIE family of receptor tyrosine kinases comprises two members, TIE1 and TIE2 (Angiopoietin 1 receptor, Tyrosine-protein kinase receptor TIE-2, Tyrosine-protein kinase receptor TEK, P140 TEK, Tunica interna endothelial cell kinase, CD202b antigen, EC 2.7.1.112 ). These receptors are expressed predominantly in endothelial cells and are essential for vessel formation where they are required for the later stages of angiogenesis and vessel maintenance. TIE2 has roles in control of microvessel sprouting, integrity, and maturation. Angiopoietin-1 (Ang1) and angiopoietin-2 (Ang2) have been identified as ligands of TIE2 receptor, which may regulate endothelial cell proliferation, differentiation and guide the proper patterning of endothelial cells during blood vessel formation. Inhibitors of TIE2 may inhibit vascular healing and tumor angiogenesis.

Testing Information

Procedure Summary:

Tie2 (h) is incubated with 8 mM MOPS pH 7.0, 0.2 mM EDTA, 0.5 mM MnCl2, 0.1 mg/mL poly(Glu, Tyr) 4:1, 10 mM MgAcetate and [gamma-33P]-ATP (specific activity and concentration as required). The reaction is initiated by the addition of the Mg/ATP mix. After incubation for 40 minutes at room temperature, the reaction is stopped by the addition of phosphoric acid to a concentration of 0.5%. An aliquot of the reaction is then spotted onto a filter and washed four times for 4 minutes in 0.425% phosphoric acid and once in methanol prior to drying and scintillation counting.

Substrate:

0.1 mg/mL poly (Glu,Tyr)

Tracer:

33P

ATP Concentration:

[ATP]= 200µM (Km= 439µM )

Incubation:

40 min at Room temperature

Control Inhibitor:

Staurosporine

Test Sample Requirements:

Please provide compounds dissolved in 100% DMSO (PBS or HBSS prohibited).
Stock solution should be ≥50× the final assay concentration (a 10 mM stock is also acceptable).
Required volume:
– <60 kinase assays: 120 µL of 50× stock
– ≥60 assays: 420 µL of 50× stock
If you supply 10 mM stocks or powder (pre-weighed), we will apply the appropriate conversion.
For batches of ~50 compounds supplied as solids, the TAT will be extended.
