Isoenyzyme analysis can determine the species identity of your cell line and determine if your cell line has been contaminated by a cell line of a different species.

Example of isoenzyme gel banding patterns used to determine species identity.

Standard Isoenzyme Analysis includes:

Determination of the isoenzyme gel electrophoresis banding pattern for at least three of the following enzymes:

• Glucose - 6 - Phosphate Dehydrogenase (G6PD)

     NOTE: Other isoenzyme analyses are available

From the banding patterns of the enzymes used, a "process of elimination" is employed to determine the species identity of the cell line.
