Description In many cases the isolation of cells is the first step for gene expression studies or in diagnostic procedures. Besides biological separation techniques physical separation methods are most commonly used. These methods use physical differences such as size and weight of the particles to be separated. For this purpose so-called separation solutions (also known as centrifugation media or density gradient media) are used. Pancoll separation media from PAN-Biotech contain a polysaccharide with a molecular weight of 400,000 daltons. This hydrophilic polymer allows production of aqueous solutions for cell separation with a density of up to 1.119 g/ml. PAN-Biotech offers a variety of ready-to-use products with a density of 1.063 g/ml up to 1.119 g/ml for a very wide range of cell isolation applications. As the densities of blood fractions and the osmolality are different among species these parameters are optimized in Pancoll rat, Pancoll mouse and Pancoll animal. Specifications Pancoll Human: Cell Separation Medium, Density: 1.100 g/ml Density: 1.100 g/mL EDTA: Without EDTA Endotoxin Content: < 0.3 EU/ml HEPES: Without HEPES Liquid / Powder: Liquid Product Category: Cell Separation Media Product Type: Pancoll Cell Separation Media Size: 500 ml bottles Sterile: Yes Storage Temperature: +2°C - RT Manufacturer: PAN-Biotech GmbH Country of Origin: Germany Method of Separation Pancoll is available in different densities of the separation solution (e.g. 1.068 g/ml, 1.077 g/ml). The density is the key parameter to choose the appropriate solution for the target fraction (see table 1).
