The cell culture supernatant (sample) can be stored for several days at 4 °C before using the kit to determine if mycoplasma is present. For long-term storage, the samples can be stored at -20 °C, either in their native state or after heat inactivation.

Mögliche Ursachen und Abhilfemaßnahmen für Probleme, die bei der Vorbereitung von Proben für SDS-PAGE (Natriumdodecylsulfat-Polyacrylamid-Gelelektrophorese) auftreten, und Optimierung der Elektrophoresebedingungen.
Identify causes and remedies for SDS-PAGE sample preparation challenges and optimize electrophoresis conditions.
Detect mycoplasma contamination in cell culture through the PCR, DNA stain, or culture tests. Discover mycoplasma prevention, elimination, and detection kits.
Know when to use antibiotics to prevent bacterial or fungal, mycoplasma, or viral contamination in cell culture and find suitable antibiotics or other biological agents.
Protokolle
Mycoplasma contamination of cell cultures is a serious issue impacting cell model validity. PCR testing for mycoplasma is an inexpensive, sensitive, and specific method for detecting contamination.

Can I freeze the samples to collect several before using them?
1 answer-
Samples should be cell supernatants when possible. Cell pellets are not recommended. The high concentration of DNA in the pellet is often responsible for the non-specific bands. If cell pellets are the only material available for testing, then centrifugation is necessary following sample boiling in order to remove all cell debris.

The sample required for VenorGeM® Mycoplasma Kit, Product MP0025, is a cell culture supernatant. Is this from adherent or suspension cells?
1 answer-
The mycoplasma assay kit can be run on supernatants from either adherent or suspension cells. The centrifugation step during sample preparation will remove any cellular debris to limit PCR inhibitors.

When using Product MP0025, VenorGeM® Mycoplasma Kit, there is inhibition in the sample (no internal control band). Can the sample be diluted and the assay repeated?
1 answer-
Sigma Aldrich does not recommend diluting the sample and re-assay as this can result in false negatives (sample diluted below the detection limits of the assay). Sigma Aldrich recommends that PCR inhibitors be removed using a DNA extraction with commercially available kits. (Product Codes G1N10, G1N70, NA2000).

Product MP0025, VenorGeM® Mycoplasma Kit, does not contain TAQ. What DNA polymerase should be used?
1 answer-
Any DNA polymerase with a 3’-5’ exonuclease activity is NOT recommended. These include Tli, Pfu,and Pwo. Those DNA polymerases that can be used include Taq, Tfl, and Tth. The kit has been optimized for use with Product No. D9307.

What is the difference between Product No. MP0025 (VenorGem Mycoplasma Detection Kit) and Product No. MP0035 (Lookout Mycoplasma Detection Kit)?
1 answer-
The assay kits have a similar range of species detected (see product insert for listing). For Product No. MP0025, the components are supplied as individual reagents. For Product No. MP0035, the components are supplied in reaction tubes, already mixed and ready for addition of sample and Taq. The internal control for Product No. MP0035 is at 481 bp rather than 191 bp as found in Product No. MP0025.

Can a cell lysate be used in the VenorGeM® Mycoplasma Kit, Product MP0025, assay?
1 answer-
A cell lysate can contain PCR inhibitors. Sigma Aldrich recommends that PCR inhibitors be removed using a DNA extraction with commercially available kits. (Product Codes G1N10, G1N70, NA2000).
