Cell-based assay for the detection of mycoplasma in cell cultures
PlasmoTest™

Colorimetric mycoplasma detection assay

PlasmoTest™ is the first cellular assay for the visual, colorimetric detection of mycoplasma contamination in cell cultures.

  • Requires only basic cell culture knowledge
  • Hands-on time < 1 hour. Results after overnight incubation
  • Detects 5.102-5.105 cfu/ml mycoplasma contaminants
  • Detects bacterial contaminants
  • No false positive: a positive result indicates the presence of a cell culture contaminant

PlasmoTest™ features two major components:

  • the mycoplasma sensor cells, HEK-Blue™-2 cells
  • the HEK-Blue™ Detection medium

HEK-Blue™-2 cells recognize mycoplasmas through Toll-like Receptor 2 (TLR2), a pathogen recognition receptor.

In the presence of mycoplasmas, TLR2 initiates a signaling cascade leading to the activation of NF-kB and other transcription factors.

These transcription factors induce the secretion of SEAP (secreted embryonic alkaline phosphatase) in the supernatant.

SEAP activity is readily detected by the purple/blue coloration of the HEK-Blue™ Detection medium. HEK-Blue™ Detection is a medium specifically designed for the detection of SEAP.
