Carboxyl coupling resin consists of 6% cross-linked agarose with covalently linked diaminodipropylamine (DADPA) to generate a free primary amine at the end of a long spacer arm. Molecules, including proteins, peptides and nucleic acids, are covalently coupled to the free primary amines, and the stable columns are ideal for affinity purification of antibodies and other interacting partners.

Potassium acétate 3 mol/l (3 N) en solution aqueuse

Supplier: G-Biosciences

Protein-S-S-Reductant™ uses TCEP (Tris [2-carboxyethyl] phosphine), a popular alternative to β-mercaptoethanol and DTT (dithiothreitol). TCEP improves stability, increases effectiveness, and reduces proteins over a wider range of pH, including lower acidic pHs. Protein-S-S-Reductant™ completely reduces stable disulfide bonds in less than 5 minutes at room temperature and is compatible with the protein alkylation reactions. This ready to use solution is at a neutral pH and stabilised for long-term storage. Simply supplement Protein-S-S-Reductant™ in place of DTT or β-mercaptoethanol and boil the sample.

Mode of action and anti-microbial spectrum streptomycin sulphate is an aminoglycoside antibiotic and has a bactericidal action against many gram-negative bacteria. It binds to the #12 protein on the ribosomal 30S subunit and inhibits protein synthesis.

Many lysis buffers and reagents used in sample preparation are incompatible with routinely used electrophoretic analysis. The presence of contaminants, or interfering agents, such as salts, acids, bases and detergents, result in band distortion and poor protein resolution. As a result, SDS-PAGE gels are hard to analyse and lack reproducibility. PAGE-Perfect™ is a simple, two-step method for concentrating, cleaning and preparing protein solutions for running publication quality gels.
