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).
Relocalization of junctional adhesion molecule A during inflammatory stimulation of brain endothelial cells.

'Junctional adhesion molecule A (JAM-A) is a unique tight junction (TJ) transmembrane protein that under basal conditions maintains endothelial cell-cell interactions but under inflammatory conditions acts as a leukocyte adhesion molecule. This study investigates the fate of JAM-A during inflammatory TJ complex remodeling and paracellular route formation in brain endothelial ... More
Improved throughput traction microscopy reveals pivotal role for matrix stiffness in fibroblast contractility and TGF-ß responsiveness.

'Lung fibroblast functions such as matrix remodeling and activation of latent transforming growth factor-ß1 (TGF-ß1) are associated with expression of the myofibroblast phenotype and are directly linked to fibroblast capacity to generate force and deform the extracellular matrix. However, the study of fibroblast force-generating capacities through methods such as traction ... More
Exosomes reflect the hypoxic status of glioma cells and mediate hypoxia-dependent activation of vascular cells during tumor development.

'Hypoxia, or low oxygen tension, is a major regulator of tumor development and aggressiveness. However, how cancer cells adapt to hypoxia and communicate with their surrounding microenvironment during tumor development remain important questions. Here, we show that secreted vesicles with exosome characteristics mediate hypoxia-dependent intercellular signaling of the highly malignant ... More
Baculovirus-mediated gene transfer into mammalian cells.
Authors:Boyce FM, Bucher NL,
Journal:Proc Natl Acad Sci U S A
PubMed ID:8637876
This paper describes the use of the baculovirus Autographa californica multiple nuclear polyhedrosis virus (AcMNPV) as a vector for gene delivery into mammalian cells. A modified AcMNPV virus was prepared that carried the Escherichia coli lacZ reporter gene under control of the Rous sarcoma virus promoter and mammalian RNA processing ... More
BacMam technology and its application to drug discovery.

The recombinant baculovirus/insect cell system was firmly established as a leading method for recombinant protein production when a new potential use for these viruses was revealed in 1995. It was reported that engineered recombinant baculoviruses could deliver functional expression cassettes to mammalian cell types; a system which has come to ... More
