Want to quickly check your protein’s molecular weight?
To check that an affinity tag has been completely removed?
To check your sample for protein contaminants?
Mass ID is your solution.
Most MS-based proteomic experiments performed today belong to the “bottom-up” family. Proteins are first digested into peptides, then these are analysed and the results are used to obtain protein-level information.
It is possible to work with intact proteins in low-complexity mixtures. This can be a convenient and fast way to assess the purity of a protein sample or to check that the protein present in the sample has the expected Molecular Weight (MW).
DC Biosciences offer Protein Mass Identification (Mass-ID) analysis of your protein sample. Simply provide the sample and information regarding buffer composition and we will take it from there.
