Identify single proteins by MALDI MS
Would you like to identify the single most abundant protein present in a 1D gel band or 2D gel spot? Just send us the gel band/spot and we’ll identify this protein by its mass spectrometric peptide fingerprint. Trypsin in-gel digestion is followed by MALDI MS and MALDI MS-MS analysis of the most abundant peptides. We search your data against a public protein database from UniProt. This database contain amino acid sequences for more than 80 million proteins. Each month the databases are updated to consider all known proteins.
