In vitro Kinase assay for ATM.
Step 1: Preconjugation of ATM antibody
antibody( Novus: NB100-104) 2.5 ug
Protein A - sepharose slury 30 uL
TBST 200 uL
in 0.5mL tube
o/n 4 degree.
Step 2: reaction( depend on your purpose)
Step 3: ATM IP by Protein A-ATM antibody complex bead
reaction (about 100-50 uL) + complex
4 degree 2 hours.
wash.
Step4: Kinase reaction
ATM IP complex + P53-GST fusion peptide(10 ug)
buffer C: 10uL
150 mM KCL: 10 uL
GammaP(32) ATP: 1 uL
32 degree for 30 min.
Step 5: GST poul-down
Glutathione bead: 30 uL
4 degree, 2 hours
Step 6: 60 uL SDS lameli buffer boiling
Tricks: using long tip to suck out all the buffer in the beads.
wash by TBST 1-2 times
