FREE Collagenase Sampling Program!

Providing researchers with the best combination of cell yield and viability is the aim of the Worthington Collagenase Sampling Program. The lot-to-lot variation which is typical of crude collagenase makes it important to pre-test a particular lot in many applications. As the world’s leading manufacturer of collagenase Worthington is able to offer the greatest number of different lots at any given time and can recommend specific lots for an application. Under the program Worthington provides individual researchers with 100 mg samples of up to three different lots of collagenase FREE OF CHARGE, for evaluation in their own application. A period…

Expression of a stable green fluorescent protein mutant in group B streptococcus. Growth, detection and monitoring, with the CLARIOstar®

CLARIOstar® multi-mode microplate reader from BMG LABTECH can measure tryptophan with fluorescence intensity detection. The CLARIOstar can use either filters or combine filters and LVF monochromators™ for an accurate and sensitive detection of tryptophan. Features of CLARIOstar: Increased sensitivity over conventional monochromators Continuously adjustable bandwidths (8 to 100 nm) and wavelengths (320 to 850 nm) Combined use of LVF monochromators™ and filters in the same measurement Full-spectrum UV/Vis absorbance measurements in less than 1 second Dedicated, high-energy laser for AlphaScreen® and AlphaLISA® Automated focal Z-height adjustment for top and bottom readings Includes multi-user control and MARS data analysis…
