Antimicrobial agent for primary cells

Primocin™ is the first antibiotic formulation designed to offer complete protection of primary cell lines from microbial contaminations.

  • Active against both Gram+ and Gram- bacteria, mycoplasmas and fungi
  • No need to add Penicillin or Streptomycin
  • Non-toxic to primary cells

Primocin™ contains four compounds. Three of these compounds act on Gram+ bacteria, Gram- bacteria, and mycoplasmas by blocking DNA and protein synthesis. The fourth compound eradicates fungi, including yeasts, by disrupting ionic exchange through the cell membrane. 

Primocin™ has been used successfully with many primary cells, including mouse- and human-tumor derived cell lines [1], embryonic cells [2] and induced pluripotent stem cells [3-6].
