Beskrivning: 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.

Beskrivning: Även om optimerade analysförhållanden är det bästa sättet att uppnå optimala resultat så är det både tidskrävande och dyrt att göra om gelelektroforesprocessen och testa varje ny primär antikropp eller antikroppskoncentration. Restore™ Western blot-strippingbuffert är ett effektivt alternativ.

Beskrivning: 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.

Beskrivning: The 1-Step™ Ultra TMB-ELISA contains soluble TMB (3,3´,5,5´-tetramentylbenzidine) 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 and provides greater sensitivity than the blue product. The 1-Step Ultra TMB-ELISA is supplied ready to use with no mixing required.
