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