Strong Points: Many different tools beyond basic calculator
Weak Points: None




For the peptide chemist (or anyone who works with proteins or mass spectrometry), the Chemistry Lab Suite app provides a number of useful reference charts and calculators in one handy app. The app is divided into four sections: solutions, proteins, peptide synthesis, and chemicals. The “solutions” tab provides the standard stock and dilution calculators, as well as a list of buffers for different pH ranges. Under the “proteins” section, users will find references for amino acid and peptide properties, as well as tools for mass spectrometry, such as a calculator for peptide fragmentation and a tool to identify mass shifts. The “peptide synthesis” section contains information and protocols related to peptide coupling and resin loading. Finally, users will find a molecular weight calculator and tools related to chemical elements and metabolite identification under the “chemicals” section of the app.
