Anybody any experience with this (now discontinued) kit? We did a lot
of work using the kit on the basis that the supplied substrate was
specific for the EGF receptor associated tyrosine kinase. We are now
getting feedback from Journal referees that the substrate may also be
phosphorylated by TK associated with erbB2/B4 or erbB2/EGFR
heterodimers. Anybody any info on this - we can't get any from
