Can I take the ToxiLight™ Non-Destructive Cytotoxicity BioAssay Kit to look at the kinetics of cell death?

Yes, by taking a sample of the culture media (usually 20µl) into a fresh luminometer plate this can be assayed with the Adenylate Kinase Detection Reagent supplied in the Toxilight kit to look for increased levels of AK over the control. The rest of...

Are the human mesenchymal stem cells (PT-2501) more prone to become differentiated down one lineage over the other?

...differentiation if allowed to reach confluence. As such, to maintain cells as undifferentiated cells, it is critical to subculture cells when they are subconfluent....

Where are Lonza’s Normal Human Neural Progenitor (NHNP) and Normal Human Astrocytes (NHA) cells isolated from?

Lonza’s Normal Human Neural Progenitor (NHNP) and Normal Human Astrocytes (NHA) cells are primarily isolated from the cerebral cortex (or forebrain from cerebral hemisphere) from fragmented fetal brain tissue (16-20 weeks old).

When I transfected my cells, error 8 appeared on the display of the Nucleofector® IIN, IIS or 2b. What is the reason?

...to the incomplete delivery; however, the cells can still be plated for analysis. This generally occurs because the conductivity of the solution was outside of accepted limits – this can happen if the media was not completely aspirated before resuspending, too much...

I tested my cell culture supernatant negative for mycoplasma contamination using the MycoAlert® Mycoplasma Detection Kit or the MycoAlert® PLUS Mycoplasma Detection Kit. But when I tested the same cells using a PCR-based Assay, I obtained a positive result.

It is possible that the PCR is picking up dead mycoplasma whereas the MycoAlert® and MycoAlert® Plus Assay will pick up only viable mycoplasma. It is possible of course that there is contamination in the PCR giving a false positive.

How much sample do you need for accurate results with MycoAlert® Assay? Do you need cells or just supernatant?

The standard protocol calls for taking 2 ml of culture media, spinning down any cells and removing 100 µl of supernatant as sample.Smaller initial aliquots of media may be taken to start with if necessary.

Can I use the ToxiLight™ Non-Destructive Cytotoxicity BioAssay Kit to assess the effect of transfection procedures on the health of my cells?

...Kinase are present in your transfected cells culture supernatant indicating that they have been damaged by the transfection procedure. This would impact on your transfection efficiency values...

What optimization is necessary to get the Nucleofector® Technology to work?

None. For each cell type in our product list we offer a cell-type specific solution and thoroughly optimized electrical parameters. These are already pre-programmed in the Nucleofector® Device. Additionally our optimized protocols give you...

Do we have any Diseased Human Bronchial/Tracheal Epithelial Cells (DHBE) screened for Air Liquid Interface (ALI) differentiation using the B-ALI™ BulletKit™?

Yes. All our DHBEs are also offered in a version screened for ALI differentiation. The lots which do pass this additional ALI testing are electronically designated by adding an “S” to the end of the original catalog number.

What cell number do I need per well when using the 96-well Shuttle® Device or the 4D-Nucleocuvette® Stripes?

The cell number is very much dependent on the cell type you use. For high throughput Nucleofection®, we usually start with one fifth of the optimal amount recommended for the standard Nucleofection® in the 100µl cuvette. Currently the absolute...
