Intact protein mass analysis 0-50 kDa
MALDI-MS analysis is a very good and fast technique to determine the intact protein mass weight up to 50 kDa. The main advantage of MALDI-MS compared to the ESI-MS is that the full mass spectrum can be interpreted without any deconvolution step. The analysis therefore gives a good indication of purity and complexity of protein and peptide samples. We use ESI-MS for proteins up to 250 kDa.
