A growing list of Invitrogen kinases have been validated for use with the Adapta® Universal Kinase Assay Kit and corresponding substrates. Please view our Adapta® Assay Reactivity Table to see if your kinase has been validated with the Adapta® Assay.
The Adapta® Universal Kinase Assay measures kinase activity by detecting ADP formation. Most of the signal change occurs in the first 10-20% conversion of ATP to ADP (Figure 2). This is in sharp contrast to kinase assays that measure ATP depletion, in which 20% conversion of ATP to ADP results in only a 20% signal change. As a result, the Adapta® Universal Kinase Assays produces high Z’-factors at low % conversions and is ideally suited for use with kinases with low activity since less ADP has to be formed to achieve an optimal assay window.
|Figure 2—Assay signal as a function of percent conversion of ATP to ADP. A representative ATP-ADP titration curve highlights the large change in assay signal at only 20% conversion of ATP to ADP. This makes the Adapta® assay ideally suited for use with kinases with low activity since less ADP has to be formed to achieve an optimal assay window.|
In addition to the Adapta® Universal Kinase Assay Kit, we offer a selection of lipid and peptide based substrates for use with the Adapta® Assay. Both the lipid and peptide substrates were designed and optmized with assay performance in mind.
Our lipid substrates were designed for optimal performance in the Adapta® Universal Kinase Assay with our PI3 kinases.
Since lipid kinases are often highly sensitive to reaction conditions, such as the type and concentration of detergents and salts, we have optimized buffers for each PI3 kinase in our collection.
A list of substrates and buffers currently available from Invitrogen for use in the Adapta® Universal Kinase Assay, can be found below.
The following is a list of kinases which have been validated using the Adapta® Universal Assay Kit. Please check back often as we are continuously validating additional kinases.
The table also includes the recommended substrate and buffer to run the assay as outlined in the assay conditions section. 5X Kinase Buffer A is included with the purchase of the Adapta® Assay Kit.
