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
Targeted genome editing with Zinc finger nucleases (ZFNs) has a wide variety of applications, and three key modes of action have been a focus thus far: targeted gene knockouts, targeted gene integration, and targeted gene correction.
The CRISPR/Cas genome editing system has revolutionized most every aspect of the life science industry. Until recently, the most used formats for this technology have been plasmids, mRNA, or lentivirus.
As part of the CHOZN brand promise to enable the development of better biologics and safer manufacturing processes, we have identified a gene target (SLC35A1) that upon elimination of expression by gene editing, results in a CHO cell line that
Bacterial transformation is a process of horizontal gene transfer by which some bacteria take up foreign genetic material (naked DNA) from the environment. Bacteria that can take up free, extracellular genetic material are known as competent cells.
Deciphering the genetics of neuroscience has always been challenging. Heterogeneous tissue microenvironments, complex genetic interactions and phenotypes, lack of model systems that accurately mimic the human brain transcriptome - not to mention the blood-brain barrier - make genetic perturbation analysis
Our scientists’ years of experience and Sigma-Aldrich’s access to multiple advanced gene editing technologies allow us to offer a cell engineering service with unparalleled success. We can engineer a variety of modifications in your cell line of choice to address
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.
Prime Editing is a novel variation on CRISPR systems which expands the guide RNA’s responsibility to serve two purposes: (1) to guide Cas9 to a targeted genomic location, and (2) to serve as an RNA template to copy new sequences
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.
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.
We are a leading supplier to the global Life Science industry with solutions and services for research, biotechnology development and production, and pharmaceutical drug therapy development and production.
