Trypsin/Lys-C Mix, Mass Spec Grade, is a mixture of Trypsin Gold, Mass Spectrometry Grade, and rLys-C, Mass Spec Grade. The Trypsin/Lys-C Mix is designed to improve digestion of proteins or protein mixtures in solution.   Using the conventional trypsin digestion protocol (i.e., overnight incubation at nondenaturing conditions), Trypsin/Lys-C Mix improves protein digestion by eliminating the majority of missed cleavages,…

Trypsin is a serine protease that specifically cleaves at the carboxylic side of lysine and arginine residues.   The stringent specificity of trypsin is essential for protein identification. Native trypsin is subject to autolysis, generating pseudotrypsin, which exhibits a broadened specificity including a chymotrypsin-like activity. Such autolysis products, present in a trypsin preparation, would result in addition…

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

mosquito crystal helps scientists to automate and streamline liquid handling workflows in protein crystallography drop setting and beyond while enhancing research quality and productivity. 

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…

Grid Screen Salt HT combines Grid Screen Ammonium Sulfate, Grid Screen Sodium Malonate, Quik Screen and Grid Screen Sodium Chloride into a single 96 Deep Well block format. The block contains 1 ml of each reagent. Features: A systematic grid screen varying salt or polymer or organic versus pH Samples pH 4 to 9 Combine reagents within or between screens to customize your screen Combine reagents between rows or colum…

Reliable Drop Setting: Reduce Costs + Increase Reproducibility The NT8 ® - Drop Setter/Crystallization Robot is a fast, nanoliter-volume liquid handler with drop dispensing capability, including setting drops for Lipidic Cubic Phase (LCP) experiments. The 8-tip head aspirates and dispenses drops from 10 nL to 1.5 μL.

Upgrade your crystallization screens with the New Industry Standard: The Crystal16 benchtop crystallization system.

Build Crystallization Screens with Ease The FORMULATOR ® - Screen Builder is a next-generation liquid handler specifically designed for Protein Crystallography that uses patented microfluidic technology to dispense up to 34 different ingredients to design even the most complex optimization screens. A 96-nozzle dispensing chip can dispense any volume of any ingredient of any viscosity into any well.

The Crystal Phoenix is the ideal protein crystallography dispenser, featuring accuracy, speed and precision to make it the perfect instrument for sitting drop, hanging drop and microbatch reactions. In less than 50 seconds it dispenses protein and screen to the small wells or hanging drop seals. The speed of dispensing the screen and protein eliminates the problem of evaporation even when dispensing as little as 100 nanolite…
