Mycoplasma is the smallest and simplest prokaryotic organism. There is a risk of mycoplasma contamination during cell culture, and mycoplasma contamination of cells has become a common problem worldwide.
Mycoplasma contamination may seriously affect the state of cells, change the gene expression and metabolic characteristics of cells, lead to slow cell growth, abnormal differentiation and death, and seriously affect cell function.
Bacteria, yeast or mold contamination in cell culture can be seen under an optical microscope, but mycoplasma contamination is usually not visible under an optical microscope and must be detected by specific detection methods.
Common methods for detecting mycoplasma contamination include mycoplasma isolation and culture, special biochemical tests such as ELISA and luminescence, and DNA fluorescent staining detection. Among the above detection methods, most of the operation steps are relatively cumbersome, the sensitivity is not high, the mycoplasma types cannot be distinguished, special instruments are required, or the time required is long. The qPCR method is relatively simple and convenient to operate, and the results can be obtained in 2 hours.
• Provide results in less than 2 hours.
Good negative and positive controls.
• No live mycoplasma required: The MycoSEQ Mycoplasma Detection Kit does not contain any live mycoplasma and does not require the use of live mycoplasma for validation
• Can be used with gDNA, inactivated mycoplasma, or live mycoplasma
• Can be used as an alternative to the standard 28-day culture test
• Can be used in conjunction with culture-based methods to provide preliminary results while awaiting the 28-day test results
The MycoSEQ Plus Mycoplasma Detection Kit is part of an integrated workflow for adventitious drug, impurity, and contaminant detection during biopharmaceutical manufacturing. The entire workflow includes the sample preparation kit, which provides a manual sample preparation method, which together with the qPCR analysis can provide results in 2 hours. (Please note that complex matrices may require additional upfront processing steps as described in the various available protocols.)

DuckyBio’s Mycoplasma PCR Detection Kit is a TaqMan™-based quantitative PCR (qPCR) kit for detecting mycoplasma contamination in biological materials such as cultured cells. Designed and tested using criteria often applied toward rapid mycoplasma detection in biotherapeutic manufacturing cell culture lot release, the MycoSEQ Plus kit enables results that meet or exceed guidance on sensitivity and specificity expectations as described in European Pharmacopoeia (E.P. 2.6.7, 2007), US Pharmacopoeia (US63) and Japanese Pharmacopoeia. When used with a suitable sample preparation method, the MycoSEQ Plus kit can detect less than 5 CFU/mL.
For the detection of Salmonella spp. in food, animal feed and in environmental samples from the food production area as described in ISO 6579-1:2017.
Meat extract and casein provide a source of nitrogen and amino acids and sodium chloride maintain theosmotic balance. Ox bile and brilliant green act as selective agents against non-target microorganisms. Tetrathionate is generated from the sodium thiosulfate. Iodine and calcium carbonate buffer the sulfuric acid generated from tetrathionate reduction.
