How can I increase the transduction efficiency with the BacMam 2.0 reagents such as the the CellLight and Premo products?
Try varying particle-to-cell ratio (PPC), incubation volume, temperature and, cell density (if adherent cells are transduced). For adherent cells, we recommend a confluence of about 70%. Following the PPC, adjusting the volume is the next best parameter to change to optimize protein expression. If that doesn't work, you can also use the BacMam Enhancer Kit (Cat. No. B10107).
Standardized mitochondrial analysis gives new insights into mitochondrial dynamics and OPA1 function.

'Mitochondria form dynamic tubular networks through processes of fission and fusion. Defect in mitochondrial dynamics lead to various pathologies, including several common and some rare neurodegenerative disorders. OPA1 and MFN2 are two key players in mitochondrial fusion associated with Autosomal Dominant Optic Atrophy and Charcot Marie Tooth neuropathy type 2A ... More
High-resolution mapping reveals topologically distinct cellular pools of phosphatidylserine.

'Phosphatidylserine (PS) plays a central role in cell signaling and in the biosynthesis of other lipids. To date, however, the subcellular distribution and transmembrane topology of this crucial phospholipid remain ill-defined. We transfected cells with a GFP-tagged C2 domain of lactadherin to detect by light and electron microscopy PS exposed ... More
Ketamine induces toxicity in human neurons differentiated from embryonic stem cells via mitochondrial apoptosis pathway.

'Ketamine is widely used for anesthesia in pediatric patients. Growing evidence indicates that ketamine causes neurotoxicity in a variety of developing animal models. Our understanding of anesthesia neurotoxicity in humans is currently limited by difficulties in obtaining neurons and performing developmental toxicity studies in fetal and pediatric populations. It may ... More
Faecal excretion of ciprofloxacin after a single oral dose and its effect on faecal bacteria in healthy volunteers.
Authors:Pecquet S, Ravoire S, Andremont A,
Journal:J Antimicrob Chemother
PubMed ID:2211433
'High concentrations of ciprofloxacin have been shown to persist in the faeces of volunteers for several days after a week of oral treatment with this drug, which was also found to have a prolonged effect on aerobic Gram-negative intestinal bacteria. To determine whether a shorter course of ciprofloxacin would have ... More
Energy metabolism in human pluripotent stem cells and their differentiated counterparts.

'BACKGROUND: Human pluripotent stem cells have the ability to generate all cell types present in the adult organism, therefore harboring great potential for the in vitro study of differentiation and for the development of cell-based therapies. Nonetheless their use may prove challenging as incomplete differentiation of these cells might lead ... More
