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...

In Air-Liquid-Interface (ALI) Culture, won't the apical surface of B-ALI™ Cells dry out?

No, the cells secrete fluid at the apical side but also moisture is drawn through the cell layer from the basal layer.

How can I remove the cells from the 100 uL Nucleocuvette® Vessel after Nucleofection®? Is there any alternative?

We recommend using the plastic single use pipettes provided in the kits. These pipettes prevent any damage to the cells and ensure a good cell recovery.

Which Nucleofector® Protocol should I use for genome editing and transfection of CRISPR/Cas9 into my cells?

Please use always the ready-to-use protocol for the specific cell type. The optimized programs are cell type specific and do work for any kind of substrates. You can transfect small and large DNA vectors, mRNA, siRNA, gRNA, peptides and proteins...

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.

Do I need to shake the plate after adding the Cell Lysis Reagent during the ViaLight™ 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.

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...

What protocol should I use for Nucleofection® of patient derived blood samples, e.g. leukemia or lymphoma cells?

Unfortunately, we do not have a ready-to-use protocol for Chronic lymphocytic leukemia (CLL) or other blood cell derived cancer cells. The cells often have a chromosomal aberration and show the properties of a cell line. Therefore we suggest...
