What age are the mice and rats that your Clonetics Mouse and Rat Astrocytes are isolated from?

They are embryonic. The rats are E18 or E19 and the mice are E14 or E15.

My suspension-adapted HEK293 (or CHO) cells tend to clump in culture. How can I avoid this?

Efficient protein production experiments require growth of the host cell in single-cell suspension, something that is sometimes difficult to achieve since most established cell lines retain their adherent growth characteristics. Commercially...


How can I improve Human Hepatocyte viability post Nucleofection on the 96-well Shuttle device?

In addition to proper cell handling and using culture media optimized for long term culturing of hepatocytes (Lonza Basal medium supplemented with BulletKit), we recommend separating the healthy hepatocytes from the dead cells and debris in the...


Do the Clonetics Rat and Mouse Astrocytes require an extracellular matrix for plating?

No, they simply need to be seeded onto tissue culture treated plastic. For best performance, we recommend to use positively charged plasticware

What is the best way to centrifuge Human Hepatocytes prior to Nucleofection?

In order to avoid cell compaction in the pellet and difficulties in cell resuspension, we recommend using round bottom 2 ml vials or 50 ml BD Falcon™ tubes for all centrifugation steps prior to Nucleofection™.

What age are the rats that your Clonetics Rat DRGs are isolated from?

The Rat Neonatal Dorsal Root Ganglion (DRG) Neurons (R-DRG-505) are isolated from neonatal, about 2-3 days old.The Rat Embryonic Dorsal Root Ganglion (eDRG) Neurons (R-eDRG-515) are isolated from embryonic rats (E14-15).

How many mycoplasma species exist? Which are the usual suspects in cell culture?

More than 180 species have been identified of which 20 distinct Mycoplasma and Acholeplasma species from human, bovine and swine have been isolated from cell culture. There are 6 species that account for 95% of all mycoplasma infections (M.orale,...

When can I start induction studies on Human Hepatocytes transfected with the Nucleofector®?

We recommend allowing the transfected hepatocytes to recover in Plating medium for 72 hours post-Nucleofection®.For induction studies (e.g. CYP3A4), the Plating medium is replaced with maintenance medium (William's E without FCS and EGF) and...
