Types of Cell Culture Contamination The two main forms of cell culture contamination are chemical and biological. Chemical cell culture contamination refers to the adulteration of a cell culture with nonliving substances that have a negative impact on the culture system.
To getting the cells for culture must be isolated from a donor animal tissue or organ. The cell culture may be divided into three according to their history: 1) primary, 2) secondary and 3) continuous cell culture. The primary and secondary cells are usually diploid cells.Primary cell lines derived directly from an intact tissue like animalâs embryo or kidney.Secondary cells are derived from primary cultures. And the continuous cell lines are usually derived from malignant tissue.o getting the cells for culture must be isolated from a donor animal tissue or organ.
