Merck tentacle media capture biomolecules
Merck KGaA, of Germany, has launched new tentacle media for the capture of viruses, proteins, antibodies and DNA. Fractoprep media consist of long polymer chains - the tentacles - that are bound firmly to Fractoprep beads, thus enabling efficient separation of the desired biomolecules from the respective solution.
Merck KGaA, of Germany, has launched new tentacle media for the capture of viruses, proteins, antibodies and DNA. Fractoprep media consist of long polymer chains - the tentacles - that are bound firmly to Fractoprep beads, thus enabling efficient separation of the desired biomolecules from the respective solution.
In contrast to other sorbents such as dextran, agarose or cellulose, Fractoprep is an extremely stable, synthetic polymer, the company says. This means that large quantities of biological materials such as blood serum, the supernatant from cell cultures or whey are chromatographed effectively and reliably at high flow rates and reduced throughput time.
The hydrophilic matrix provides large-sized pores on the inside between the intertwined polymer strands for the free diffusion of proteins. Fractoprep also has an extremely long lifespan and can be used repeatedly, thus saving the user both time and costs.
Merck KgaA also featured its Calcium Pidolate as active product ingredient and calcium salt for the sup-plementation of pharmaceuticals.
The soluble calcium salt is claimed to offer the greatest absorption of Ca++ and, therefore, greater bioavailability than other calcium salts on the market. It combines independent absorption regardless of gastric pH, high solubility and bioavailability and has good gastro-intestinal tolerance.
