Custom Protein Ubiquitination Services

Custom Protein Ubiquitination Services

Ubiquitylation is one of the most prevalent post-translational modifications (PTM) within cells. Ubiquitin modification induces protein degradation, which effect on protein function, localization and activity. Therefore, the study of protein ubiquitination plays an important role in cell biology and drug discovery. As a professional PROTAC services provider, Profacgen offers various ubiquitin services to help our customers to accelerate research progress and obtain better results.

In Vitro ubiquitin conjugation reactions

In vitro ubiquitin conjugation reactions are relatively quick and simple method to carry out and answer to whether protein interested ubiquitinated, is it mono-ubiquitinated, poly-ubiquitinated, or multi-mono-ubiquitinated and what E2 or E3 ligase is it. Profacgen provides services to perform ubiquitin reactions in vitro and analyze the results.

Assay to measure protein ubiquitination in living cells

Our ubiquitin assays could measure all types of ubiquitination on a target protein in living cells. With our bioluminescence resonance energy transfer (BRET) methods, which can study the dynamic ubiquitination of target protein and understand which cellular functions are regulated by ubiquitylation.
