Popis: Pierce BCA™ (bicinchoninic acid) reagents provide accurate determination of protein concentration with most sample types encountered in protein research. The Pierce BCA™ Protein Assay can be used to assess yields in whole cell lysates and affinity-column fractions, as well as to monitor protein contamination in industrial applications. Compared to most dye-binding methods, the BCA™ Assay is affected much less by protein compositional differences, providing greater protein-to-protein uniformity.

Popis: These devices can be used for a wide range of applications including low molecular-weight contaminant removal, buffer exchange, desalting, equilibrium dialysis, and concentration. The cassette membrane is composed of low-binding regenerated cellulose and features a hermetically sealed sample chamber to maintain the highest possible sample retention. This type of membrane is compatible with a number of common chemicals and buffers. The colour-coded transparent frames of the Slide-A-Lyzer® cassette allow instant recognition of the MWCO of the membrane and make viewing the needle easier during sample injection.

Popis: The Pierce™ TMB Substrate Kit contains soluble TMB (3,3´,5,5´-tetramethylbenzidine) that is ideal for sensitive ELISA-based applications. TMB is a chromogenic substrate for horseradish peroxidase. Once oxidised by the enzyme, this substrate yields a blue product that absorbs at 370 nm and 652 nm. Adding sulfuric or phosphoric acid to stop the reaction changes the product to yellow that absorbs at 450 nm.

Popis: Some antibodies are difficult to remove from Western blots and require Longer incubation times or incubation temperatures greater than 22 °C. Restore™ PLUS Western Blot Stripping Buffer was developed to reduce incubation times while keeping incubations at room temperature. High-affinity antibodies can be quickly and effectively stripped from Western blots without removing transferred proteins, thereby allowing multiple reprobes of the target.
