Automated membrane protein screening, optimization, and scale-up to empower better protein crystallization research. 

The PCT Pre-Crystallization Test is used to determine the appropriate protein concentration for crystallization screening. Sample concentration is a significant crystallization variable. Samples too concentrated can result in amorphous precipitate, while samples too dilute can result in clear drops. Precipitate and clear drops are typical crystallization screen results for reagent conditions which do not promote crystallizati…

The HRP is purified by repeated affinity chromatography of root extracts from horseradish. The result is an enzyme of high specific activity. Our horseradish peroxidase is purified in large scale by the use of benzhydroxamic acid agarose giving a product of high purity and specific activity. The product consists mainly of the basic isoenzymes and are supplied as lyophilized powder. Activity: >250 U/mg (25°C, Guaiacol as hydr…

HRP-StabilPLUS™ gives superior stabilization of HRP-conjugated proteins in dilution. The stabilization covers low as well as high protein dilutions. The HRP-StabilPLUS™ allows the manufacturer of diagnostic assays to provide pre-diluted ready-to-use enzyme conjugates. This improves day-to-day variation by eliminating the chance of errors in dissolving or diluting concentrated conjugates. The Stabilizer does not contain azide…
