Zeocin is a formulation of phleomycin D1, a glycopeptide antibiotic and one of the phleomycins from Streptomyces verticillus belonging to the bleomycin family of antibiotics.[1] It is a broad-spectrum antibiotic that is effective against most bacteria, filamentous fungi, yeast, plant, and animal cells. It causes cell death by intercalating into DNA and inducing double stranded breaks of the DNA.[2][3]

Properties

Zeocin is blue in colour due to the presence of copper ion Cu²⁺. The copper-chelated form of zeocin is inactive. When zeocin enters a cell, the Cu²⁺ is reduced to Cu⁺ and then removed, and zeocin becomes activated and can then bind DNA.[1]

Usage

Zeocin and other related chemicals in the bleomycin family of compounds are primarily used in molecular biology as an antibiotic, especially for the selection of eukaryotic cell lines when used in conjunction with vectors containing a selectable marker for zeocin resistance. Zeocin is considerably cheaper than phleomycin, works better in minimal media, and is therefore often used preferentially in studies.[4]

Resistance to zeocin is conferred by the product of the Sh ble gene first isolated from Streptoalloteichus hindustanus.[5] The Sh ble gene product binds the antibiotic in a one-to-one ratio so it can no longer cause cleavage of DNA. This resistance gene is used as a selectable marker in some cloning and expression vectors where zeocin is used as the antibiotic for selection.[6][7]

gollark: Nope, it's mostly static. The SSG is actually a horrible Node script.

gollark: The website.

gollark: What osmarks.tk does is actually just make the site mostly static and have some JS pull in comments and stuff.

gollark: It is not perfect. It looks bad.

gollark: It would:- possibly be slower to load on slow internet connections- not support accessibility- not support text highlighting- not be responsive
