BioTools software allows the identification and detailed characterization of proteins and peptides using various types of mass spectra. This includes database search of single spectra and combined MS and MS/MS datasets, the import of search results and further detection of modifications and mutations. The RapiDeNovo module provides extensive de-novo sequencing capabilities. BioTools also supports various top-down sequencing spectra types for intact protein characterization and enables the annotation and database search of these data. PolyTools™ 2.0 is a program for the interpretation of MALDI mass spectra of polymers. It accepts peak lists and automatically detect the repeat unit, cation and end groups upon loading of the lists. It also calculates characteristic parameters of the chain length distribution like |molecular weight average|, |polydispersity| or |degree of polymerization|. It displays the results in tabular and graphical representation and can export both for further use in other programs. Kendrick Mass Defect (KMD) analysis of the data is possible as well and a variety of KMD analysis types/plots is available (KMD, KMD-RNKM, RKM and RKM-RNKM). smartbeam II (DPSS) Used in autoflex max MALDI TOF TOF.
