  1. a) Upper 6 species of mycoplasmas are the most common contaminants of cell cultures [11, 12].
  2. b) This broad-range TaqMan PCR can detect many species of mycoplasmas [22].
  3. c) This nested PCR is highly sensitive, and it is used to check for mycoplasma contamination in the Cell Bank of BioResource Centre, Riken Tsukuba Institute, Tsukuba, Ibaraki, Japan [21].
  4. d) PCR assay for sequencing of mycoplasmas designed in this study. Partial Match means that 2 or 3 of the total of 4 nested-PCR primers match to available regions of the tuf gene on the public database.
