Molecular cloning is a set of techniques that utilizes vectors to transfer recombinant DNA into host cells and is an essential tool for investigating the expression of genes and proteins in bacterial or mammalian cells. A variety of vectors optimized for gene cloning and expression in a range of host organisms are available, alongside competent cells for genetic replication. Here, you can explore a range of molecular tools, high-quality genomic and cDNA libraries, premade clones, transformation and transfection reagents and mutagenesis or gene expression detection assays and expression arrays. Find the best gene expression and molecular cloning products in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.
