MP Biomedicals provides a complete solution for safe cell culture and reliable results!

Working with mammalian cell lines requires mycoplasma-free conditions, but oftentimes cell cultures get contaminated from multiple sources which can become a nuisance. The presence of mycoplasma can literally alter many cellular processes and cause malfunctions of cells in proliferation, protein synthesis, DNA transfection etc. Early detection and fast elimination can ensure the reliability, reproducibility, and consistency of your cell culture research.

The most convenient and effective option for eliminating mycoplasma infection in cell cultures is to add mycoplasma removal agent (MRA) to remove and prevent many types of mycoplasmas with reliable results. MRA ensures high elimination efficiency and optimal cell viability at the lowest dose for the shortest treatment time (Fig. 1). Only 0.5 µg/mL for one week can keep cell culture mycoplasma free (Fig. 2), as referenced in 550+ leading publications

Mycoplasma Removal Agent ensures:

  • Fastest (1 week) with lowest dosage (0.5µg/ml) for total mycoplasma elimination
  • Elimination of multiple mycoplasma species
  • Prevention of recontamination
  • Sterility and optimal cell viability
  • Compatible with mammalian cell lines
  • Extensive citations in publications (over 550)


Participate in our Mycoplasma Survey for your chance to win a bottle of MRA

Tell us about your mycoplasma experience for an entry to win a free bottle of Mycoplasma Removal Agent (MRA, SKU 093050044, 5 mL, $294 value). The survey will take approximately two minutes to complete. Your answers will allow us to better meet your expectations and provide suitable products for your research needs. To be eligible for the drawing of a free bottle of MRA, please complete the survey by Sunday November 22, 2018.  Your answers will be used only by MP Bio to improve our customer experience.
