High-efficiency CRISPR genome-editing tools for multiplex editing
The GeneArt® CRISPR Nuclease mRNA is wild type Cas9 as mRNA, for genome editing using CRISPR-Cas9 technology. Ready-to-transfect Cas9 mRNA circumvents the need for time-consuming cloning steps required when using CRISPR vector systems. Cas9 mRNA can be co-transfected with in vitro transcribed guide RNA (IVT gRNA) or a synthetic gRNA expression cassette containing U6 promoter. The gRNA expressing cassette and IVT gRNA template can be ordered as GeneArt® CRISPR Strings™ DNA, a 500 bp DNA fragment. Following transfection, the Cas9 protein is directed by gRNA to target specific genomic locus. This system allows multiplex genome editing, where multiple target gene sequences can be edited simultaneously in a single transfection reaction with the addition of multiple gRNAs. The system is versatile and simple to use, and changing target specificity only requires a change in the design of the GeneArt® CRISPR Strings™ DNA.

For convenient and secure sterile connection of flexible tubing in large volume operations.
Kleenpak II sterile connectors allow for the dry connection of two separate fluid pathways, while maintaining the sterile integrity of both, even in an uncontrolled environment. The connector consists of a male and a female connector, each covered by an aluminum peel-away strip that protects the port and maintains the sterility of the sterile fluid pathway prior to connection.
The Kleenpak II sterile connector has been designed to allow for the connection of large processing equipment in order to obtain fast, safe and reliable sterile transfer of large volumes.With this sterile connector, large single-use systems ( > 100 L), such as the AllegroTM systems, will be operated at much faster speeds. There will be minimal fluid restriction in thetubing lines.
Different connector options are available to allow for the connection of 19 mm (3⁄4 in.) and 25.4 mm (1 in.) ID nominal tubing including a 25.4 - 38.1 mm (1 - 11⁄2 in.) sanitary flange compatible fitting for maximum operational flexibility. Kleenpak II sterile connectors can be either gamma irradiated to a maximum of 50 kGy or autoclaved up to 130°C to suit different processing requirements.
The µDAWN™ Multi-Angle static Light Scattering (MALS) detector performs absolute characterization of macromolecules eluting from UHPLC, determining molar mass and size independently of retention time and molecular reference standards.
The µDAWN™ Multi-Angle static Light Scattering (MALS) detector performs absolute characterization of macromolecules eluting from UHPLC, determining molar mass and size independently of retention time and molecular reference standards. This instrument offers superb sensitivity over a wide range of molar mass, size and concentrations. In most respects the µDAWN is similar to the well-established miniDAWN™ TREOS™, a workhorse MALS instrument used in hundreds of labs around the world for characterizing proteins and other molecules smaller than 50 nm in radius.
Distinctly from the miniDAWN, the µDAWN is uniquely suitable for use in conjunction with UHPLC Size Exclusion Chromatography (µSEC-MALS) thanks to its small interdetector dispersion. In some cases it may be used with ion-exchange or other types of chromatography. Regardless of the specifics, the µDAWN produces minimal band broadening in order to maintain the narrow peaks typical of UHPLC.
The µDAWN may also be used in microbatch (off-line) mode or in conjunction with a Calypso IICG-MALS system for characterization of macromolecular interactions: affinity and absolute stoichiometry, label-free and immobilization-free, as well as second virial coefficients, cross virial coefficients, average molar masses and sizes.
