MolWeight app for iPhone and iPad

MolWeight is a simple tool for scientists and students that allows calculation of the molecular weight and other key properties of peptides and oligonucleotides from their sequence. In addition, a calculator is provided for determining the molecular weight of any substance from its chemical formula.

Features:
- Calculate molecular weight, molar extinction coefficient, melting temperature and GC content for DNA or RNA
- Calculate molecular weight, molar extinction coefficient and isoelectric point for peptides
- Choose between common terminal modifications for oligonucleotides and peptides
- Calculate formula weights using average or monoisotopic atomic masses

MolWeight is easy to use. Just enter your sequence using one-letter codes and the molecular properties are recalculated as you type. MolWeight performs accurate weight calculations and estimates other properties using high-quality, fully documented algorithms.

Bring your calculations into the lab where you need them!
