What's the difference between trypsin and accutase?
Description
Both trypsin and accutase represent mixtures of different proteolytic enzymes. Trypsin is prepared from porcine pancreas accutase from invertebrates. Accutase can replace trypsin for the detachment and dissociation of anchorage-dependent cells from surfaces and can also be used on suspension cells to reduce clumping in preparation for counting. The advantages of accutase over the traditional trypsin treatment are that it is more gentle and less damaging to cells (leading to increased viability) and does not contain any mammalian or bacterially derived proteins. Accutase is more thermolabile than trypsin and usually doesn't require an inactivation step.
