General description

The SIG10 5a Chemically Competent Cells share the most useful genetic elements of standard cloning strains like DH5α and directly replace them in cloning protocols.
They provide the performance researchers need with ease of use as only common laboratory equipment is required and provide solutions for a wide range of applications at economical prices.

Bacterial Transformation

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.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
