Cas9-Mediated Recombineering Enhances Metabolic Production of Kdo2-Lipid A by E. coli
In this article, we present an application of our novel E. coli CRISPR/Cas-mediated Lambda-Red (λ-Red) homologous recombination (HR) vector system, which facilitates gene editing through the homology-directed repair (HDR) of double-stranded DNA breaks (DSBs) created by Cas9 endonuclease, using either
Long Oligos
Our experience with gene construction and microarray development provides us with insight into the potential difficulties of long oligo synthesis. We have developed techniques to purify long oligos, which are unmatched by other suppliers.
MISSION® Lentiviral Controls
When conducting shRNA experiments, proper controls are a key element of experimental design. Proper use of controls permits accurate interpretation of knockdown results and provides assurance of the specificity of the observed phenotype. We offer a variety of positive, negative
Lentivirus Cell Line
Using lentivirus as a means to deliver shRNAs has become standard practice in many labs exploring RNAi.
Reverse Transfection of Plasmid DNA
Automation is used for many applications to reduce variation caused by manual handling and to obtain reproducible results in high-throughput assays. High-throughput applications, such as knockdown studies or target screenings, often include cell transfection.
Nuclease-Free Water at Your Fingertips
An ultrafiltration cartridge can be placed at the outlet of a water purification system to deliver nuclease-free ultrapure water.
TRC Design and pLKO.1 Vector FAQs
The MISSION® shRNA clones, designed by the TRC, are pre-cloned into the pLKO.1-Puro vector. This lentiviral vector allows for propagation in bacterial culture and selection of inserts in mammalian cells.
Small Molecule CRISPR Enhancers
Modulation of homology-directed repair (HDR) within the context of CRISPR-genome editing has led to the identification of small molecules that enhance CRISPR-mediated HDR efficiency in various cell types.
shRNA Gene Families Sets
The MISSION® shRNA Library gene family sets are collections of genes related to specific cellular/molecular pathways documented in NCBI, Gene Ontology (GO), Protein Lounge, and Ingenuity Systems. Our Bioinformatics team has methodically mapped all TRC shRNA clones to each set.
CRISPR-based Gene Activation
Sigma has developed a gene activation system based on a fusion of dCas9 to the catalytic histone acetyltransferase (HAT) core domain of the human E1A-associated protein p300.
