Cell culture grade HEPES (powder). Buffer strength for cell culture applications is usually in the range of 10 to 25 mM. Studies have indicated that 20 mM HEPES is the most satisfactory concentration of the buffer when both Hanks’ and Earle’s solutions are used.

Lipase

Pancreatin is a mixture of digestive enzymes produced by the exocrine cells of the pancreas. It is composed of amylase, lipase and protease. The trypsin found in pancreatin works to hydrolyze proteins into oligopeptides; amylase hydrolyzes starches into oligosaccharides and the disaccharide maltose; and lipase hydrolyzes triglycerides into fatty acids and glycerols.
