Do you have any recommended methods for detaching human monocytes from the plate for assaying or before Nucleofection®?

We have had good results by incubating the cells in ice cold PBS for 10 minutes and then rinsing the plates. Alternatively, the cells can be detached without a medium change by gently pipetting the cell suspension up and down. Our experience has...

Do I need a pure neuronal culture for Nucleofection® ?

In principle, it should be absolutely fine to nucleofect pure neuron cultures (e.g. after purification by Ficoll). Glial cells are not necessary for transfection. What one would have to consider for example, is to get the required number of neurons...

How should I purify my DNA for Nucleofection® of neurons?

...suppliers. The presence of endotoxins can increase cell mortality and this is especially true of sensitive cells such as primary neurons. The presence of endotoxins can increase cell mortality and this especially true of primary cells such as neurons...

What is the difference between Lonza’s BEGM™ medium and the Growth Media portion of Lonza’s B-ALI BulletKit™ Medium?

Lonza’s BEGM™ medium and the Growth Media portion of Lonza’s B-ALI BulletKit™ Medium are essentially the same and can be used interchangeably (for example, cells could be cultured in Lonza’s BEGM™ medium just prior to differentiation using...

Can I use the Nucleofector® Technology for RNAi applications? How do I start?

Yes. The Nucleofector® Technology can be easily applied for any RNAi substrate (siRNA, shRNA, miRNA). You can use the same conditions described in the cell type specific Optimized Protocol for DNA vectors (cDNA, shRNA or miRNA expressing plasmids...

How are Lonza's CD14+ monocytes isolated?

Lonza's CD14+ monocytes are isolated first by obtaining mononuclear cells from peripheral blood via density gradient centrifugation. The CD14+ cells are then isolated form the mononuclear cell population using either positive or negative...

How do you calculate a population doubling?

A population doubling is the total number of population doublings of a cell type since its initiation in vitro. The number of population doubling is calculated using the following equations:Cell count at day of passage /Cell count 24 hours...

What is the purpose of EDTA in trypsin? 

EDTA is a chelator of metal ions like calcium and magensium. It is used with trypsin because it helps bind up the divalent cations in the medium. It helps to keep the cells from sticking to each other.  If its not there….you would need a higher...
