Re: p38

[Daniel caffrey <dcaffrey@rcsi.ie>]

Dear kinasers,

If we are to believe the many expts by the  Davis lab, Cobb lab, Cohen
lab  etc.,  then Phosphoamino acid analysis and kinase ACTIVITY assays
would suggest, in general, a correlation between dual phosphorylation
and activity.

It has been mentioned before that NEB and Santa cruz abs may not as
reliable as the traditional assays!
Would people aggree or disagree with this statement?
