VWR® PerfectBlue Maxi ExW 'Revolution', Wide format gel system

Catalog Number: (700-0912)
Supplier: VWR Collection
Description: The Maxi ExW 'Revolution' offers built-in buffer recirculation - without the need for pumps or additional tubing. The Maxi ExW 'Revolution' offers the same high throughput, rapid separation as the Maxi ExW model but, with the position of the cathode and a rising tube, the system uses hydrogen bubbles to slowly mix the buffer. This system thereby avoids the build-up of pH or ionic gradients for electrophoresis of maximum quality and stability.

Optimizer Buffer™ for optimal cross-linking and modification

Supplier: G-Biosciences
Description: The conjugation and modification reactions used to cross-link proteins or couple labels to proteins, such as biotin, enzymes, and fluorescent dyes, require certain conditions, including pH and chemical composition for optimal conjugation. Many common buffers routinely used in laboratories have an inhibitory effect on conjugation reactions; for example, Tris buffers inhibit coupling to amines.

VWR® PerfectBlue Mini L Revolution, Gel System

Catalog Number: (700-0799)
Supplier: VWR Collection
Description: The 'Revolution' series includes a buffer circulation system, powered by the electrodes themselves. Hydrogen bubbles produced at the cathode pass up a diagonally positioned pipe connected to the two sides of the tank producing a gentle circulation of the buffer. The result is no pH and ionic gradient – without need of mechanical pumps.
