What are SingleQuots Kits?

A SingleQuots™ Supplements and Growth Factor Kit contains several vials that may include growth factors, FBS, and antibiotics in pre-measured aliquots - designed to be added to a bottle of basal medium. The concentrations of these factors are...

What is the lowest amount of Human Hepatocytes that can be used with the 96-well Shuttle® System or the 4D-Nucleofector® X-Unit?

Human hepatocytes do not like to be cultured and transfected at low densities. Therefore, using less than 100,000 cells per Nucleofection® is not recommended.

What is the function of retinoic acid in the BEGM® media? 

In vivo, bronchial epithelial cells differentiate along an abnormal squamous pathway under conditions of retinoid deficiency. The squamous phenotype is characterized by the induction of specific markers such as keratin 13, and the enzymes...

What kind of effects could a mycoplasma contamination have on my cells?

Mycoplasma contamination can: > Inhibit cell metabolism > Cause cell death > Induce morphological alterations > Alter DNA, RNA, and protein synthesis > Induce chromosomal aberrations > Cause increased sensitivity to inducers of...

Do I need to add antibiotics to your Clonetics Media? What is GA-1000?

For most Clonetics™ Media, gentamicin-amphotericin-B mixture is provided at a final concentration of 30 µg/ml gentamicin and 15 ng/ml amphotericin-B. This antibiotic mixture is provided in a red-capped vial labeled GA-1000.

What are mycoplasmas?

How often do mycoplasma contaminations occur in cell cultures?

A conservative estimate states that between 15-35% of all continuous cell cultures are contaminated with mycoplasma (Drexler HG, Uphof CC; 2002), some estimates are even higher (up to 80 % in some countries (Koshimizu K, Kotani H; 1981).

How can I detect mycoplasma contamination of my cells?

We recommend using the 20-minute MycoAlert® Mycoplasma Detection Kit from Lonza. The simple four-step MycoAlert® Assay is a selective biochemical test that exploits the activity of mycoplasmal enzymes. The presence of these enzymes provides a rapid...

Can I use a medium other than the one you offer to culture Clonetics® Cells?

We have an optimized medium for each Clonetics® Cell type. The cells are grown and tested in their specific medium system. Lonza guarantees the performance of Clonetics® cells only if appropriate Clonetics® media and reagents are used...

How can cells be cured of mycoplasma contamination?

Where contamination has occurred, and the sample absolutely cannot be discarded, the MycoZap™ Mycoplasma Elimination Reagent has been optimized to eliminate mycoplasma with minimal toxic effects on the cells. The MycoZap™ Reagent eliminates...
