Antibiotics & Antimycotics

Antibiotics and Antimycotics

Antibiotics and Antimycotics are a type of antimicrobial drug used in the treatment and prevention of bacterial infections. They may either kill or inhibit the growth of microorganisms.

In science those substances are mostly used in cell culture. They are used to select for a specific type of cells. Either when cultivating mammal cells to exclude bacteria or e.g. to select for genetically modified cells which carry a resistance gene for selection on them.

PanReac AppliChem antibiotics and antimycotics prove to be used from small assays to bigger incubators. On this page you can find a selection of our finest most common used products from this product range.

Also here it is about trust and reproducibility for all your experiments and growing in cell culture or microbiology.
