Experiment Helper

Experiment Helper is a lightweight lab utility app for molecular biology, biochemistry, and chemical biology workflows. The app provides quick calculators and lookup tools for common bench tasks, including protein property calculation, DNA/RNA translation, dilution planning, transfection setup, cell seeding calculations, and CAS number lookup. Features include: • Protein property calculation from protein, DNA, RNA, or UniProt accession input • Molecular weight, theoretical pI, extinction coefficient, GRAVY, aliphatic index, estimated half-life, and amino acid composition • DNA and RNA translation into protein sequence • UniProt lookup for retrieving protein sequences from accession numbers • Dilution and dilution-factor calculators • Transfection plasmid calculator • Cell seeding calculator • CAS number lookup using PubChem, including compound formula, molecular weight, structure, and related properties Experiment Helper is designed for students, researchers, and laboratory scientists who need fast, transparent calculations at the bench or while planning experiments. Most calculations run locally on your device. Network access is used only for selected lookup features, such as retrieving protein sequence information from UniProt or compound information from PubChem.
