This chapter focuses on the identification of proteins. Instrumentation and analysis parameters that affect the success rate, as well as the methods and software for improving identification, are discussed in the chapter. In all proteomics experiments, regardless of the protein separation used, protein...
Protein identification Mascot Serveris the trusted reference standard for protein identification by mass spectrometry for 25 years. Mascot is designed for high throughput, and has no limits on the number of users, the size of the searches or the size of sequence databases. It continues to be cit...
We offer services for large scale proteomic profiling and can provide sample pre-fractionation using our off-line UHPLC-UV platform. Our laboratory can also perform Protein Identification services using solution samples or gel-isolated samples. ...
Mass spectrometry (MS) is a common method for identification of proteins. Nano-Traps are beneficial for MS analysis following Co-IP, because of their reliable performance, high affinity, and low background of protein contaminations.

Protein identification Mass spectrometry in protein identification Regardless of the question, the mainstay of proteomics is protein identification. In current laboratory practice, protein identification and mass spectrometry (MS) are nearly synonymous because MS allows for ...
For acetyllysine identification, all data sets were also searched using the Mascot in-house search engine against a custom database representing Htt protein spanning residues 1–612 fused to an N-terminal myc tag peptide. The following search parameters were used: enzyme specificity was defined as...
Mass spectrometry (MS) is a common method for identification of proteins. MS is particularly helpful for protein-protein interaction assays or interactome studies, which aim to identify the interacting partners of a protein within a cell at a time point. Nano-Traps are beneficial for MS analysis...
