Gene Expression and Molecular Cloning Products & Reviews

The TOPO™ XL-2 Complete PCR Cloning Kit provides all the necessary elements for efficient cloning of extra-long PCR products (up to 13 kb).

The second generation of our QuikChange method that provides improved fidelity over our original kit, while maintaining greater than 80% mutation efficiency for single site mutagenesis.

The StrataClone PCR Cloning Kit allows high-efficiency, 5-minute cloning of PCR products at room temperature, using the efficient DNA rejoining activity of DNA topoisomerase I and the DNA recombination activity of Cre recombinase. These kits are available for both blunt-end and UA cloning. 

Our Mycoplasma Plus PCR Primer Set detects infection by all forms of Mycoplasma with a robust single-band PCR product (triplet for Acholeplasma). This kit also includes controls to verify PCR amplification and Mycoplasma genomic DNA. The primer design permits higher annealing temperatures, reducing spurious bands from PCR contaminants.

The original QuikChange Site-Directed Mutagenesis Kits eliminate the need for subcloning into M13-based bacteriophage vectors and for ss-DNA rescue. This makes site-directed mutagenesis studies simple and reliable since it allows oligo-mediated introduction of site-specific mutations into virtually any double-stranded plasmid DNA. 

The High Sensitivity ß-Galactosidase Assay Kit provides an easy, rapid, and sensitive method for determining the ß-galactosidase activity in the lysates of cells transfected with a ß-galactosidase expression construct. Rapid, simple and sensitive >= 10-fold increase in sensitivity over ONPG-based kits Reduces amount of cell extract needed for assay Useful for cells that are difficult to transfect and have low ß-gal expression…

Human iPSC-derived glutamatergic neurons expressing Cas9 for rapid gene knockout generation

The new InjectMan® 4 is ideal for microinjection into adherent cells, smaller organisms and embryos in the early stages of development. The combination of InjectMan 4, FemtoJet® 4i or 4x enables a fast, semi-automatic injection. Furthermore, the InjectMan 4 is the ideal micromanipulator for all complex applications that require a dynamic movement mode and direct control of the injection process via the joystick button. The ax…

The ONE-Glo™ Luciferase Assay System provides a highly sensitive, robust, homogeneous assay for detection of firefly luciferase reporter gene expression in mammalian cells. Ideally suited for high- and ultrahigh-throughput applications, the ONE-Glo™ Assay contains a new luciferase substrate, resulting in a reagent that is more stable, more tolerant to sample components, and has less odor than standard luciferase assay reagents…

The LigaFast™ Rapid DNA Ligation System is designed for the efficient ligation of sticky-ended DNA inserts into plasmid vectors in just 5 minutes (blunt-ended inserts in as little as 15 minutes).   Rapid ligation is based on the combination of T4 DNA Ligase with a unique 2X Rapid Ligation Buffer to speed up and streamline your cloning experiments. The LigaFast™ System is designed to eliminate any further purification pri…
