Our LanthaScreen kinase activity assay toolbox of "mix and match" assay reagents is designed to enable rapid assay configuration. Our portfolio of phospho-specific antibodies, matched fluorescent peptide substrates and in-house produced kinases have been tested in >200 different kinase assays to date.

Phospho-specific Antibodies with Peptide Substrates

To facilitate in-house kinase assay configuration and screening, we have developed a selection of Tb-labeled phospho-specific antibodies, which may be accessed in small scale and screening quantities.  Matched and validated substrates are available for kinase assay configuration.

These antibodies may also be available with Europium labels, contact us at discoverysciences@invitrogen.com, for more information.

Phospho-specific Antibodies with Physiological Protein Substrates

As an extension to our peptide-based substrates for LanthaScreen® kinase activity assays, we now offer physiological protein substrates that are directly labeled with a green fluorescent protein (GFP) acceptor fluorophore. Pairing the GFP-labeled substrate with a corresponding terbium (Tb)-labeled phosphospecific antibody allows detection of the phosphorylated product.
