Antibioticsare essential in retaining the purity for a particular selection factor in a population of cells. Resistance to a variety of harmful antibiotics that interfere with desirable protein synthesis can be conferred through the use of cell culture products. AG Scientific has had particular success in the manufacture and supply of the following antibiotics.
Hygromycin Bis a standard antibiotic that selects for exclusively hygromycin resistant cells.
Puromycinis an antibiotic that inhibits translation via premature chain termination; it is toxic to both prokaryotic and eukaryotic cells.
Blasticidinkills both eukaryotic and prokaryotic cells by inhibiting peptide bond formation. Resistance to blasticidin occurs with expression of one of three genes: bsr, bls, or BDS.
G418inhibits polypeptide synthesis in prokaryotic and eukaryotic cells and is structurally related to gentamycin.
AG Scientific delivers quality assured antibiotics for gene selection and cell culture directly to scientists, from small-scale to bulk orders. Our leadership in bulk supply allows us to provide custom product packaging and create multiple product forms. We offer “just in time” delivery, private labeling, and custom formulations for specific research needs.

*Please inquire the availability for this product. Actagardin is a high molecular weight tetracyclic antibiotic produced by several species of Actinoplanes. Actagardin is an antibiotic in which the macrocyclic rings are formed by thioether, rather than disulphide, bridges. Actagardin is a potent Gram positive and Gram negative antibiotic. Actagardi
*Please inquire the availability for this product. Alamethicin F50 is a neutral linear peptaibol complex with potent antibiotic activity, containing 20 “amino acids” with acetyl and phenylalaninol termini, produced by Trichoderma sp.. Alamethicin F50 acts an ionopohore, transporting ions through membranes and artificial lipid membranes. Alameth
*Please inquire the availability for this product. Albofungin is a polyaromatic heterocycle containing a rare N-aminoamide, isolated from a Streptomyces species in Russia in 1959. Albofungin exhibits a broad biological profile with antibiotic, antifungal, anthelmintic and very potent antitumor activity. The mode of action of albofungin has not been
*Please inquire the availability for this product. Amphomycin is a lipopeptide antibiotic produced by Streptomycetes and Actinoplanes, initially reported by researchers at Bristol-Myers in 1953 from Streptomyces canus. Amphomycin was marketed as a complex of closely related analogues in the 1950s and 1960s. Structure elucidation was not completed u
*Please inquire the availability for this product. Anhydrochlortetracycline is a degradation product of chlortetracycline formed by acid-catalysed isomerisation of the dimethylamino group at C4. Anhydrochlortetracycline exhibits little antibiotic activity but its abundance is indicative of poor storage and handling of chlortetracycline.
*Please inquire the availability for this product. Anhydroepiophiobolin A is a dehydrated analogue of ophiobolin epimerised at the C6 position. Anhydroepiophiobolin A is the major terminal degradation product of ophiobolin A and is co-produced with other ophiobolins in many Bipolaris species. Prior to 1984, references to “anhydroophiobolin” alm
