MycoDect™MycoplasmaDetectionKit:#MD050
ProductDescription
Mycoplasmasaresmall,roundorfilamentousprokaryoticorganismsthatlackcellwalls.Ithasbeenestimatedthatatleast15%-35%cellculturesarecontaminatedwithmycoplasma.Mycoplasmacontaminationcanmodifymanyaspectsofcellphysiologywithoutcausingobviousmediumcloudinessandapparenteffectoncellgrowth.Mycoplasmacontaminationaffectsupto80%ofcontinuouscellcultures.Ifundetected,mycoplasmacontaminationcanhavesignificanteffectsonthequalityandreliABIlityofyourcellculturepreparations.Duetotheirsmallsizeanddeformability,mycoplasmascanpassthrough0.22µmfilter.Thelackofcellwallmakesmycoplasmaunresponsivetocommonantibioticsthattargetcellwallsynthesis.Itisessentialthatallcellstocksandnewculturesenteringafacilityaretestedforthepresenceofmycoplasmaandallcellculturesshouldbetestedroutinely(e.g.onceevery2-3months)inordertomaintainamycoplasma-freeenvironment.
Manymethodsareavailablefordetectionofmycoplasma,includingisolationinbroth/agarculture,directorindirectfluorescencestaining,ELISA,immunostaining,directorindirectPCR.Amongthosemethods,directPCRisthemostsensitive,specificandconvenientmethodwhentheprimerdesignisoptimized.
TheMycoDect™MycoplasmaDetectionKitisdesignedtodetectmycoplasmainfectionincellculturesinlessthantwohours.Itcandetectmycoplasmafrombothcelllysatesandcellculturemedia.Thesensitivityisupto10-20copiesoftargetDNA,whichtranslatestolessthan10mycoplasmaspecies.Thiskitdetectsthetopfivecommonspeciesofmycoplasma,M.Hyorhinis,M.Arginini,M.Orale,M.Fermentans,A.laidlawii,whichrepresent98%oftissuecultureinfections.ItcanalsodetectMycoplasma,Acholeplasma,UreaplasmaandSpiroplasmafromothergenera.
