Description générale

Le kit de détection par PCR LookOut® pour mycoplasmes s'appuie sur la PCR (réaction en chaîne par polymérase), qui s'est imposée comme la technique de choix pour la détection ultrasensible des contaminations par Mycoplasma, Acholeplasma et Ureaplasma dans les cultures cellulaires et d'autres échantillons biologiques dérivés de cultures cellulaires. Ce kit a été testé avec succès pour l'amplification de l'ADN génomique de Mycoplasma fermentans en concentrations de 20 000 à 20 copies.
Les tubes réactionnels fournis avec le kit sont prérevêtus des dNTP, des amorces et du colorant de charge requis. Le protocole est beaucoup plus rapide qu'avec les méthodes classiques, où les tubes réactionnels doivent être chargés un par un.

Application

Questions

1–10 of 16 Questions  

  1. What is the full comprehensive list of all Mycoplasma species that the LookOut® Mycoplasma PCR Detection Kit, not test for? I am aware of the two outlined species, M. pneumoniae and U. urealyticum, but I am not sure on how these two are clinically similar

    1 answer

    1. This kit is intended for use as a mycoplasma screening and detection tool for cell culture use. It is not suitable for in vitro diagnostics use. While M. pneumoniae and U. urealyticum have been tested and found to be non-reactive, a full list of clinically associated mycoplasma species has not been determined. Please see the image below to review those species that have been tested using this kit.

  2. What is the difference between product no. MP0040A (LookOut® Mycoplasma qPCR Detection Kit) and MP0035?

    1 answer

    1. The main differences between these kits are as follows:

      For MP0035:
      •Standard PCR
      •Primers/dNTPs precoated on tubes
      •Includes tubes
      •Taq Polymerase not included
      •Requires 40 cycles at 30 seconds

      For MP0040A:
      •qPCR only
      •Primers/dNTPs require addition to the reaction
      •Does not include tubes
      •Taq Polymerase included in primer/dNTP mix
      •Requires 45 cycles at 30 seconds
      MP0035 is suitable for 24 reactions, while MP0040A is suitable for 25 reactions.

  3. What are the possible reasons for problems when trying to review results for MP0035-1KT?

    1 answer

    1. Possible reasons for problems when trying to review results for MP0035-1KT could include incomplete removal of phenol during DNA preparation by phenol:chloroform extraction, leading to poor PCR results. It is also important to ensure the use of the recommended product, D9307, JumpStart™ Taq DNA Polymerase, as internal testing has indicated occasional sensitivity issues when using polymerases from other manufacturers. Additionally, the presence of inhibitors in the samples may affect the internal control band in the results. Lastly, mishandling of the vials and loss of lyophilized reagents could compromise the sensitivity of the assay.

  4. What is the required DNA concentration of the purified sample supposed to be to ensure compatibility with the LookOut® Mycoplasma PCR Detection Kit, MP0035?

    1 answer

    1. The detection of Mycoplasma sp. with Product MP0035 - LookOut® Mycoplasma PCR Detection Kit requires less than 10 mycoplasma genomes per microliter of the sample, which is approximately 10 fg of DNA. It is important to ensure that the sample does not contain more than 100 µg/ml of DNA to limit non-specific amplification.

  5. What are the components of the rehydration buffer for MP0035? Can the rehydration buffer M4694 be substituted by another buffer?

    1 answer

    1. The rehydration buffer M4694 in Product No. MP0025 cannot be substituted by the PCR buffer P9367, and vice versa. The composition of the PCR 10X reaction buffer P9367 in the MP0025 kit is 100 mM Tris-Hcl, pH 8.5, 750 mM KCl, 30 mM MgCl2. Similarly, the replacement of Rehydration Buffer (Catalog Number M4694) with 10X PCR Buffer, Catalog No. P2192 is not possible. The composition of the 10× buffer P2192 is 100 mM Tris-HCl, pH 8.3 at 25°C; 500 mM KCl; 15 mM MgCl2; 0.01% gelatin.

  6. When should samples be heat inactivated for using MP0035, Mycoplasma PCR Detection Kit?

    1 answer

    1. The possibility that as the slides dry, salts from the PBS are evaporating and leaving a white residue or film is considered.

      Helpful?

  7. Do mycoplasma-active antibiotics include pen/strep? Can media continue to be used with pen/strep prior to mycoplasma testing for kit R: MP0035?

    1 answer

    1. Pen/strep can be used with the cell culture before assaying with this kit. Pen/strep does not affect mycoplasma, nor does it affect the sensitivity of this kit.

  8. What is the difference between product no. MP0040A (LookOut® Mycoplasma qPCR Detection Kit) and MP0035???

    1 answer

    1. The key differences between these kit are as follows:

      MP0035
      Standard PCR
      primers/dntps precoated on tubes
      Tubes included
      Taq Polymerase not included
      Requires 40 cycles at 30 seconds

      MP0040A
      qPCR only
      primers/dntps require addition to reaction
      Tubes not included
      Taq Polymerase included in primer/dntp mix
      Requires 45 cycles at 30 seconds

      MP0035 is suitable for 24 reactions while MP0040A is suitable for 25 reactions.

  9. I purchased the JumpStart Taq DNA Polymerase in addition to the kit. This also included a 10x PCR buffer. Is this also needed or only the rehydration buffer of the kit?

    1 answer

    1. This kit has been tested and optimized for use with JumpStart Taq DNA Polymerase, Catalog Number
      D9307. The Jumpstart Taq 10X buffer supplied with the Jumpstart Taq is not used in this kit reaction set up. The Jumpstart taq is used alone with the rehydration buffer provided with the kit.
