Detection of Mycoplasma contamination in cell cultures.

Mycoplasma contamination of cell lines is a major problem in cell culture technology. This unit presents protocols involving either the polymerase chain reaction (PCR) or fluorescent in situ hybridization (FISH) to provide independent, fast, and sensitive techniques to monitor mycoplasma contamination in laboratory cultures. Special emphasis is placed on the integration of control reactions to prevent false-negative as well as false-positive results due to reaction inhibition or contamination and background staining, respectively.
