Do I need to use a gelatin, fibronectin, collagen, or Matrigel™ coating when culturing my Clonetics™ Cells?

Most Clonetics™ Cells do not require an extracellular matrix when grown on tissue culture treated plastic – flasks, dishes, well plates (with the exception of hepatocytes, and the rat/mouse neuronal and dorsal root ganglion neurons, rat cardiac...

Does it matter if the PBS used for monocyte enrichment contains calcium and magnesium, if the cells should be used later in Nucleofection®?

The PBS should be calcium and magnesium free to prevent clumping of cells. We routinely use PBS without calcium and magnesium for example Lonza Cat. No. BEBP17-516Q

Why do you recommend 7AAD instead of PI staining for cell determination in mouse macrophages?

The results obtained using 7AAD staining are much clearer than those obtained using propidium iodide (PI).  Using flow cytrometry stained and unstained, transfected and non-transfected populations can be separated much more easily.

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....

How many blood donations are pooled for pMAT cells included in the PyroCell® Monocyte Activation Test (MAT) Kit?

One production lot of pMAT cells contains equal amounts of peripheral blood mononuclear cells from four blood donations.

Do I need to shake the plate after adding the Cell Lysis Reagent during the ViaLight™ Plus Assay?

No, this is not recommended.Shaking the plate during this step can - cause frothing which will deflect the light signal away from the detection unit, - reducing the number of RLUs observed - and producing an artificially low result.

Should I add any nutritional supplementation to TheraPEAK 293-GT® Media System to support cell growth?

It is not necessary to add nutritional supplementation because TheraPEAK 293-GT® Media System is preformulated with 4 mM GlutaMAXTM, however if your process uses an alternative nutritional source you can add any supplementation required.

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.
