Swiss Mass Abacus is a calculator of peptide and glycopeptide masses. It is purposefully kept as simple as a basic calculator executing arithmetic operations. TOF-DS Proprietary: Software by Markes International used with BenchTOF time-of-flight mass spectrometers. TopFD Open source
A codon table can be used to translate a genetic code into a sequence of amino acids. [1] [2] The standard genetic code is traditionally represented as an RNA codon table, because when proteins are made in a cell by ribosomes, it is messenger RNA (mRNA) that directs protein synthesis.
It is a notation that is machine readable to render the composition and structure of peptides, proteins, oligonucleotides, and related small molecule linkers. [1] HELM was developed by a consortium of pharmaceutical companies in what is known as the Pistoia Alliance. Development began in 2008. In 2012 the notation was published openly and for ...
Peptide Mass Fingerprint search Identifies proteins from an uploaded peak list using a technique known as peptide mass fingerprinting. Sequence query Combines peptide mass data with amino acid sequence and composition information usually obtained from MS/MS tandem mass spectrometry data. Based on the peptide sequence tag approach. MS/MS Ion Search
In 1993, Bio-Synthesis was one of the first peptide synthesis companies to acquire a Finnigan MALDI-TOF mass spectrometer for the accurate quality control of synthetic peptides produced in-house. In 1994, Bio-synthesis pioneered the use of molecular methods for HLA analysis which is applied in organ matching for transplantation purposes.
At the peptide level, the signals of the reporter ions of each MS/MS spectrum allow for calculating the relative abundance (ratio) of the peptide(s) identified by this spectrum. [ citation needed ] The abundance of the reporter ions may consist of more than one single signal in the MS/MS data and the signals have to be integrated in some way ...
The claim: California counting ballots two weeks after Election Day is evidence it was ‘rigged’ A Nov. 19 Instagram post (direct link, archive link) claims one state’s lengthy vote-counting ...
The possible peptide that has the most similar spectrum will have the highest chance to be the right sequence. However, the number of possible peptides may be large. For example, a precursor peptide with a molecular weight of 774 has 21,909,046 possible peptides. Even though it is done in the computer, it takes a long time. [17] [18]
