Our lentiviral vector systems are developed with enhanced safety features. Numerous precautions are in place in the design of our lentiviruses to prevent replication. Good handling practices are a must.
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.
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.
An experiment to directly compare three methods of lentiviral transduction of Jurkat cells was conducted in order to determine the method that yields the greatest transduction efficiency.
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
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.
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.
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
After you have performed a CRISPR experiment it is important to determine which gRNAs performed successfully editing. There are many ways to validate CRISPR gene editing experiments. A quick and easy way to check for cutting is by using the
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.
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.
Nuclease-free water (or PCR water) is needed in molecular biology to avoid sample degradation during PCR, sequencing, etc. Ultrafiltration provides a quicker, safer, and more sustainable alternative to DEPC treatment when preparing RNase-free and DNase-free water.
Learn how water impurities can affect pH. Water quality defined as pure water or Type 2 water is recommended to prepare buffer solutions or measure pH.
