How long can Lonzas rat cardiac myocytes survive in culture?

Lonza has observed these cells up to 59 days in culture and even at that time, the cells displayed beating in syncytium. It is, however, possible that unseen physiological changes may occur to the cells during this time. As these cells...

Do you have recommendations for the type of samples used for the MycoAlert® Mycoplasma Detection Kit and the MycoAlert® PLUS Mycoplasma Detection Kit? And do you have recommendations related to sample storage?

The MycoAlert® Mycoplasma Detection Kit and the MycoAlert® PLUS Mycoplasma Assay require the use of cell free supernatant only! Cells MUST be removed at 200xg for 5 mins.For optimal assay performance, supernatant should be tested...

Does Lonza offer Cryopreserved Leukopaks? 

Lonza CellBio Services is pleased to announce the global availability of cryopreserved leukopaks for research use only applications. The cryopreserved leukopaks are manufactured from peripheral blood of normal human donors at a facility...

What is the proof that DNA enters the nucleus during Nucleofection®?

There are two facts that prove that the DNA is directly transported into the nucleus: 1.) Using the Nucleofector® Technology, transfection of non-dividing cells is possible. With conventional non-viral transfection methods cell division...

Does DMSO (ex. brought in with the substrate) affect Nucleofection®?

Most research paper agrees that the upper limit of cell tolerance to DMSO presence in their cell culture media is about 1% final DMSO (this might vary with the cells and media).In the case of the Nucleofection®, the DMSO will likely be transfected...

What is the function of retinoic acid in the BEGM® media? 

In vivo, bronchial epithelial cells differentiate along an abnormal squamous pathway under conditions of retinoid deficiency. The squamous phenotype is characterized by the induction of specific markers such as keratin 13, and the enzymes...

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...

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...

What is the basic principle of the Nucleofector® Technology?

The Nucleofector® Technology is a novel transfection method especially designed for the needs of primary cells and difficult-to-transfect cell lines. It is a non-viral method based on a unique combination of electrical parameters and cell...

Why is the Nucleofector® Technology ideal for transient protein production ?

For many cell lines in suspension, especially sCHO, conventional transfection methods are very limited in efficiency. For protein production, suspension cells are favored over adherent cells because they are much easier to cultivate. Unlike...
