Ready to screen kinase arrays with tyrosine- and serine/threonine-kinase substrates from annotated phosphorylation sites. Three different arrays, each with 384 spots in duplicate surrounded by red colour marks, are available. These arrays are perfect tools to characterize substrate specificities of kinases, to compare kinases, to identify autophosphorylation sites or to analyze kinase inhibitors.

Beside annotated sequences the arrays contain peptide mixtures with defined fixed positions represented by one or a few amino acids only. These mixtures can help to profile substrate specificities of unknown or new kinases.
