Biocoll
Biocoll separating solution does contain Ficoll 400® (Polysucrose 400), a polymer with a molecular weight of approx. 400,000 Dalton. Densities of up to 1.1 g/ml can be adjusted using this hydrophilic polymer. For optimal pH and osmolality, adjusting Biocoll with an acid, preferably amidotrizoeic acid (ATA), and sodium hydroxide is required. Biocoll with densities of 1.077 g/ml (cat.no. L 6113/L 6115) and 1.090 g/ml (cat.no. L 6125) are already adjusted accordingly.
