Overview

• Detection kits for Mycoplasma DNA
• Available in TaqMan format for analysis

Mycoplasma is a common and serious contaminant of cell cultures. Mycoplasma is often not visible and does not respond to antibiotics, and therefore it is a major issue that requires monitoring and early detection. Up to 30% of cell cultures may be contaminated with Mycoplasmas, the main contaminants being the species M. orale, M. laidlawii, M. arginini and M. hyorhinis. These organisms produce a variety of effects on the infected cells in culture, including changes in metabolism growth, viability and morphology, thereby altering the phenotypic characteristics of the host cells. Therefore there is an absolute requirement for routine, periodic assays to diagnose possible Mycoplasma contamination of all cell cultures, particularly continuous or established cell lines.

Storage Conditions and Product Stability
All kit components can be stored for 2 years after the date of production without showing any reduction in performance.

All kit components should be stored at -20°C upon arrival. Repeated thawing and freezing (> 2 x) of the Master Mix and Positive Control should be avoided, as this may affect the performance of the assay. If the reagents are to be used only intermittently, they should be frozen in aliquots.

The CellG3 assay reagent for the measurement of endo-cellulase (endo-1,4-β-glucanase) contains two components; 
1) 4,6-O-benzylidene-2-chloro-4-nitrophenyl-β-D-cellotrioside (BCNPG3) and 2) thermostable β-glucosidase. The benzylidene blocking group prevents any hydrolytic action by the β-glucosidase on BCNPG3.  Incubation with an endo-cellulase generates a non-blocked colourimetric oligosaccharide that is rapidly hydrolysed by the ancillary β-glucosidase.  The rate of formation of 2-chloro-4-nitrophenol is therefore directly related to the hydrolysis of BCNPG3 by the endo-cellulase.  The reaction is terminated and the phenolate colour is developed on addition of Tris buffer solution (pH 9.0).

Please note that a new assay kit (K-CellG5) is now available for the measurement of endo-cellulase.  The CellG5 reagent contains a cellopentaose core and exhibits vastly improved sensitivity for some cellulases.  In addition, the exchange of the benzylidene blocking group in CellG3 for 3-keto-butylidene in CellG5 improves the substrate’s water solubility significantly, allowing for a reduction in the concentration of DMSO required in the assay.  As DMSO is known to inhibit certain cellulases, this is another benefit in using CellG5.  Megazyme now recommends the use of K-CellG5 for all assays for the measurement of endo-cellulase.
