Should any type of extracellular matrix be used when growing undifferentiated hMSC's (human Mesenchymal Stem Cells)?

That will depend on the type of medium used. If you are using our MSCGM™ BulletKit™ PT-3001, we do not recommend using a matrix with the cells as it might induce differentiation and make the cells difficult to detach from the culture vessel. If you...

Do bacteria lead to false positive MycoAlert® Results?

NO - the lysis reagent in the MycoAlert® Assay is not strong enough to lyse bacteria / yeast. Also, the enzymes utilized are not very common in bacteria or yeast – but are universal among the mollicute family. Bacterial contamination is...

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...

What is the shelf-life for all the media associated with Human mesenchymal stem cells?

The shelf-life of the MSCGM™ Mesenchymal Stem Cell Growth Medium BulletKit™ (PT-3001) once the SingleQuots Kit is added is 30 days. For the differentiation kits:hMSC differentiation BulletKit™ – osteogenic (PT-3002)hMSC differentiation...

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...

Can mycoplasma grow in the absence of cells?

There is evidence to suggest that mycoplasma can survive in the absence of cells, some may even proliferate, but as a rule they are much more viable if cells are present. 

Is it possible to store reconstituted MycoAlert®/MycoAlert® PLUS Reagent and Substrate?

For optimal assay conditions, reconstituted reagent and substrate should be used fresh within 2 hours after reconstitution.During this time they can be kept at room temperature.For the MycoAlert® Kit: Unused, reconstituted components can be aliquoted...

Do you have any instructions available for using a hemocytometer for cell counting?

Yes. Our technical guideline "Cell Counting and Determination of Viability via Hemocytometer" can be found as associated pdf file in the link below.

What is the difference between the different cell sources (bone marrow, cord blood, or fetal liver) for CD34+ cells?

Bone Marrow: provides a hematopoietic microenvironment and the highest number of different donors.Cord Blood: more naive cells useful in transplant and stem cell research.Fetal Liver: best for developmental studies and they are highly proliferative....

What are Lonza's human Mesenchymal Stem Cells (PT-2501) cryopreserved in?

The cryopreservation medium is: 85% MSCBM 10% DMSO 5% Human Serum Albumin (w/v)
