Trypsin is a porcine pancreas-derived enzyme that is commonly used for the dissociation and disaggregation of anchorage-dependent mammalian cells and tissues. The concentration of trypsin necessary to dislodge cells from their substrate is dependent primarily on the cell type and the age of the…

Percoll® is a medium for density gradient centrifugation of cells, viruses and subcellular particles. Percoll® is composed of colloidal silica coated with polyvinylpyrrolidone (PVP), which renders the material completely non-toxic and ideal for use with biological materials. Centrifugation…

Sodium pyruvate is used by cells as an easily accessible carbohydrate source. Additionally, it is involved with amino acid metabolism and initiates the Kreb′s cycle. The 100 mM solution should be diluted 1:100 for most cell culture. The use of sodium pyruvate in Wallen fermentation medium to…

Phosphate Buffered Salts, Dulbecco's Formula (DPBS) is a balanced salt solution (BSS) used for the handling and culturing of mammalian cells. DPBS is used to to irrigate, wash, and dilute mammalian cells. Phosphate buffering maintains the pH in the physiological range. Calcium and magnesium…

RPMI 1640 was originally developed by Moore and his colleagues at Roswell Park Memorial Institute (RPMI). It was based on the RPMI 1630 line of media which utilized a bicarbonate buffering system and alterations in the amounts of amino acids and vitamins. A Dutch Modification of RPMI 1640 is also…
