Separating solutions and lectins
Separating solutions are used for isolation of cells or cellular particles during density gradient centrifugation.
Biochrom GmbH offers two different separating solutions: Biocoll and Easycoll. These two solutions differ in the respectively contained polymer. Biocoll separating solution does contain a polymer with a molecular weight of approx. 400000 Dalton. The basis of Easycoll is silica gel particles, coated with PVP (polyvinyl pyrrolidone).
The ready-made solutions are already preset on physiological values of osmolality and ph-value.
