Biological Information
Background Information:
Eph family tyrosine kinase receptors consist of two groups: EphA group members respond to ephrin-A, which is anchored to the cell membrane by glycosylphosphatidylinositol, whereas EphB group members respond to ephrin-B, containing a transmembrane domain. Among them, only EphA4 can cross-respond to both ephrin-A and -B. EphB3 (Ephrin type-B receptor 3, ETK2, HEK2, TYRO6) has been found that nearly all receptors and ligands are expressed in developing and adult neural tissue.

Testing Information
Procedure Summary:
EphB3 (h) is incubated with 8 mM MOPS pH 7.0, 0.2 mM EDTA, 10 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 24 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]= 90µM (Km= 91.07µM )
Incubation:
40 min at Room temperature
Control Inhibitor:
1-NM-PP1
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.
