The Bradford protein assay is the preferred colorimetric assay for quantifying total protein concentration. Based upon complex formation between basic and aromatic amino acid residues with Coomassie® Brilliant Blue G-250 dye, the Bradford method is easier, faster, and more sensitive than the Lowry method.

The Protein Precipitation Kit utilises a simple trichloroacetic acid (TCA) based method to precipitate proteins in complex mixtures. Only protein in the sample is pelleted, while interfering salts and surfactants remain in the supernatant. A gentle acetone wash removes TCA and co-precipitants allowing the end-user to recover the protein in a small volume of buffer.

These 50 µm thick polyester films provide secure sealing around every well, not just a cover, thus minimising evaporation, preventing spillage and well-to-well contamination, and eliminating 'edge effects' in sensitive ELISA assays. Polyester films can also be used with tissue culture plates for short-term storage, incubation, and containment of biohazards.

These 77,5 µm thick polyester films provide secure sealing around every well, not just a cover, thus minimising evaporation, preventing spillage and well-to-well contamination, and eliminating 'edge effects' in sensitive ELISA assays. Polyester films can also be used with cell culture plates for short-term storage, incubation, and containment of biohazards.

These films are 240 µm thick white vinyl with adhesive, for use with white microplates. Light reflective properties of the film, when used to seal clear bottom plates, maximise the sensitivity of bioluminescence and chemiluminescence assays in bottom-reading luminometers. White films have also been used as a backing matrix for microscopy of punch-out samples from filter plates.
