WebOne significant cell-line cross contaminant is the immortal HeLa cell line. Hela contamination was first noted in the early 1960s in non-human culture in the USA. Intraspecies contamination was discovered in nineteen cell lines in the seventies. In 1974, five human cell lines from the Soviet Union were found to be Hela. Immortalised cell lines find use in biotechnology, where they are a cost-effective way of growing cells similar to those found in a multicellular organism in vitro. The cells are used for a wide variety of purposes, from testing toxicity of compounds or drugs to production of eukaryotic proteins.
