PlasmoTest™ - Mycoplasma Detection Kit

PlasmoTest™ provides a simple, rapid and reliable assay for the visual detection of mycoplasma contamination in cell cultures. This assay is the first to utilize cells to signal the presence of mycoplasma. PlasmoTest™ - Mycoplasma Detection Kit

PlasmoTest™ features two major constituents: the Mycoplasma sensor cells and the HEK-Blue™ Detection medium.
The Mycoplasma sensor cells detect the presence of mycoplasmas leading to a color change of the HEK-Blue™ Detection medium. The Mycoplasma sensor 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 which is readily detected by the purple/blue coloration of the HEK-Blue™ Detection medium.


• Requires only basic cell culture knowledge

• Hands-on time less than 1 hour. Gives results after overnight incubation

• Detects all cell culture contaminants

• Detects 5.102-5.105 cfu/ml mycoplasmas

• No false positive: a positive result indicates the presence of a cell culture contaminant

• Test up to 250 samples

To perform further assays, only the reagents need to be reordered.

Key Features

HEK-Blue™-2 cells, the Mycoplasma sensor cells, are engineered HEK293 cells. These cells stably express TLR2 and multiple genes from the TLR2 pathway and coexpress an optimized SEAP reporter gene, placed under the control of a promoter inducible by the transcription factors NF-kB and AP-1.

HEK-Blue™ Selection is a solution that combines several selective antibiotics. These antibiotics guarantee the persistent expression of the various transgenes introduced in HEK-Blue™-2 cells. Fur thermore, Normocin™ is included in the kit to protect HEK-Blue™-2 cells from any potential microbial contamination, whether caused by mycoplasmas, bacteria or fungi.

HEK-Blue™ Detection is a medium specifically designed for the detection of SEAP. It contains a color substrate that produces a purple/blue color following its hydrolysis by SEAP.
