Selection antibiotic: cell culture tested, sterile reagent

InvivoGen is the sole worldwide producer of Zeocin™, a popular and effective antibiotic for the selection of vectors bearing the Sh ble gene in a variety of cells types (bacteria, eukaryotic microorganisms, plant and animal cells).

Resistance to Zeocin™ is conferred by the Sh ble gene product, which inactivates Zeocin™ by binding to the antibiotic. Sh ble is a small gene, only 370bp in size, carried in a number of InvivoGen’s vectors.

Zeocin™ is a copper-chelated glycopeptide antibiotic produced by Streptomyces CL990. Zeocin™ causes cell death by intercalating into DNA and cleaving it. The action of Zeocin™ is effective on most aerobic cells.
