Mice fed with the cytohesin inhibitor SecinH3 for two days develop hepatic insulin resistance that can be identified by reduced liver glycogen levels, increased serum insulin and ketone body levels and decreased serum non-esterified fatty acid. To confirm the presence and identity of SecinH3 in mouse liver, we extracted the compound from liver homogenates with chloroform and identified it by LC/MS. - [Read Extraction of the SecinH3 from Mouse Liver Protocol]
The liver of a rat is cannulated and perfused in situ with buffer, following which it is excised and perfused in a closed system with a collagenase solution. After a period of time the liver begins to break up, at which point it is transferred to a measuring cylinder and culture medium is added. It is then gently agitated to cause the release of cells which are subsequently filtered and allowed to settle out. The parenchymal and non-parenchymal cells form two distinct layers which can be separat - [Read The Isolation and Culture of Rat Hepatic Cells Protocol]
