The present application relates to a method of assaying ubiquitination in a sample by combining ubiquitin together with a substrate in a sample containing UBE1, UbcH3, Skp2-isoform 1, Skp1, Cull, Rbx1, Cks1, CDK2 and Cyclin E1 under conditions suitable for ubiquitination to take place, exposing the sample to a labelled binding partner which is specific for the ubiquitin, and measuring the amount of ubiquitin bound to the substrate.

Ubiquitination assay

The present invention related to a method of assaying ubiquitination in a sample by combining ubiquitin and two or more of E1, E2, E3 and a substrate protein in a sample under conditions suitable for ubiquitination to take place, exposing the sample with a labelled binding partner which is specific for the ubiquitin and measuring the amount of labelled ubiquitin bound to any one of the components in the sample, wherein one or more of the components in the sample comprises an immobilization tag which facilitates its immobilization onto a solid surface.
