Ubiquitination analysis is a key biochemical technology for the development of new drugs and new targets. This method can be used to detect ubiquitinated proteins; determine the ubiquitination process of these proteins; identify specific sites where lysine residues are ubiquitinated; and also be used for quantitative analysis of ubiquitination protein.
As a reliable partner of biopharmaceutical companies, Innovative Proteomics aims to provide customers with protein ubiquitination-based modification analysis services. Ubiquitination modification is a post-translational modification of proteins, which provides a powerful means for cells to regulate various biological processes. We will provide you with ubiquitination analysis services based on protein ubiquitination modification.
We Can Provide but Not Limited to:
- Identify specific proteins that undergo ubiquitination
- Identify specific sites where specific proteins undergo ubiquitination
- Identify the specific lysine residues of ubiquitinated proteins
- Identify specific sites for ubiquitination modification to recognize lysine residues
- Detection of the protein that undergoes ubiquitination is the specific ligase that causes the protein to undergo ubiquitination modification
Diagrammatic process of ubiquitination (Qiu J et al. 2016).
The Working Method and Process of Ubiquitination Analysis:
- WB+IP
It can be used for the detection of specific sites of specific proteins where ubiquitination occurs, specific lysine residues, specific sites of lysine residues, and specific ligases that cause ubiquitination modification of the protein.
- LC-MS
LC-MS can identify ubiquitinated proteins, specific modification sites of lysine, enrich ubiquitinated peptides, quantitatively analyze ubiquitinated proteins and peptides, and analyze mass spectrometry.
