The Toolbox contains a set of mass spectrometry-related utility programs which provide for calculation of oligonucleotide mass values for RNA and DNA and enzymatic cleavage fragments, and of sequence ions from collision-induced dissociation, all with provision for use of modified residues. (Code created by Jef Rozenski)
Mongo Oligo Mass Calculator
The ultimate oligonucleotide mass calculator, calculates also electrospray series, CID fragments, endo- and exonuclease fragments. Includes the possibility for calculating modified residues.
Oligonucleotide mass calculator, uses compositions as input.
Oligo Composition Calculator
Finds nucleotide compositions from a given mass. User defined residues can be included.
Calculates molecular masses and isotope ratios from elemental compositions.
Calculates elemental compositions from a given molecular mass.
SOS (Simple Oligonucleotide Sequencer) is an interactive tool for manual sequencing of oligonucleotides. It has a graphical interface and allows to determine oligonucleotide sequences from CID MS/MS data. It uses mass/intensity lists as input. Allows to check for the presence of modified residues. Runs on Windows 3.xx, WIN95/98 and WINNT computers. Is available now!
