Microsomes are sub-cellular liver structures that contain a variety of enzymes responsible for phase I metabolism.
Liver microsome and S9 incubations are used to determine the potential metabolic stability of test compounds.
Compounds are incubated at pre-determined concentrations with liver microsomes and NADPH.

  Microsome - Wikipedia, the free encyclopedia
In cell biology, a microsome is a small vesicle that is derived from fragmented endoplasmic reticulum produced when cells are homogenized.
These microsomes can be concentrated and separated from the other cellular organelles by means of differential centrifugation.
In this way, P450s in microsomes are concentrated and isolated.

Microsome preparations may be frozen and thawed a few times without substantial loss of activity.
Formany cytochrome P450 assays, a 30 minute incubation with 0.5 mg microsomal protein (humanlymphoblast-derived microsomes) or 50 pmole P450 BD Supersomes™ in 1 ml is sufficient toproduce readily detectable quantities of metabolites.
Microsomal protein can adhere to glass and exhibit lowercatalytic activity, particularly, at low protein concentrations.
