Choose from a list of all of the commonly used biological buffer systems, enter your desired volume, pH, and buffer concentration, as well as the concentrations of your stock solutions of the conjugate acid and base, and the calculator will inform you of the exact volumes of these stock solutions to mix in order to obtain the buffer needed.

adapted from Current Protocols in Immunology (Beare, et al., 2008. Monoclonal Antibodies to Human Cell Surface Antigens. Curr. Protoc. Immunology. 80:A.4A.1–A.4A.73) and includes data on the molecular weight, family, molecular structure, cellular expression patterns, function, and biomedical usefulness of the molecule. The database is searchable by the official CD designation of the antigen as well as by synonyms and other keywords including associated diseases and tissue/organ name

Type in or copy/paste any nucleic acid base sequence, any protein or peptide amino acid sequence (in one- or three-letter codes accessible from a convenient menu), or any standard chemical formula, and obtain the molecular weight. Also includes a list of 1200 of the most commonly encountered organic and inorganic compounds
