Adenovirus: weapons of mass transduction for gene delivery
Adenovirus (AV) are non-enveloped and non-integrative icosaedral viruses. Recombinant AV (genetically modified with respect to the wild-type in order to lose their capacity of replication) are widely used
Genome Editing in Stem Cells: outsource or do-it-yourself?
Many researchers are facing a dilemma: they want to set up a CRISPR genome editing project but they can't decide which cell line to use for genome editing. Even some of the most cost-effective genome editing
Using CRISPR to knockout an essential gene
Genome editing technology enabled by CRISPR and TALEN has become mainstream. Most cell biology labs are engaged in projects to create custom cell lines with knock-outs and knock-ins, and companies such
Cas9 mRNA optimized for genome editing
CRISPR/Cas9 is relatively simple to implement, as the researcher fully controls the experimental design of the tools, from the sgRNA sequence to the Cas9 protein.
Two top ways to success with knock-out
In March 2016, Mark J Osborn et al published in Molecular Therapy a major article for genome editing (doi:10.1038/mt.2015.197), about knock-out of CD3 in human T-cells. The goal is to improve T-cell-based
Simple and effective CRISPR CAS9 gene editing for primary cells
Vector-free CRISPR-CAS9 gene editing to accelerate therapeutic applications
A few years ago, Ayal Hendel et al (doi:10.1038/nbt.3290) published results revealing that chemical alterations to sgRNA enhance
Develop robust and convenient cell based assays with Gaussian Luciferase
Cell-based assays have become a classic way to monitor cells' reactions to a treatment or a specific stimulus. They involve a reporter construction and a detection system. The classic system is Firefly
Luciferase promoter reporter clones
Cell-based assays, screening for pathway activation or inhibition are classically done with promoter reporter clones expressing Firefly luciferase. Brighter, more stable, more sensitive, more convenient
shRNA set with improved performances
Optimal knock-down can be done by a shRNA sequence that depends on the gene expression level and the cell type. Usually, 4 shRNA should be tested to find the one inducing a minimum of 70% increase of the
ORF expressing Lentiviral system
ORF expression in Mammalian cells is very useful for many applications: protein production with HEK293, over-expression of tagged protein for immuno-tracking or immuno-precipitation, development of a cell
Gene knock-out in hard-to-transfect cells
Gene knock-out, which is gene editing leading to loss of function, just requires delivering into cells the 2 CRISPR system actors: the CAS9 endonuclease and the specific guide RNA to target the gene of
