Antibiotics Used in Molecular Biology

antibiotics.jpgAntibiotics are used in a wide range of techniques in molecular biology. My aim with this post is to provide an easy reference to some of the main antibiotics used in molecular biology, their mechanisms, range and working concentrations. I hope you will find it useful. If I have missed out an antibiotic that you use routinely in your work, please feel free to contact me or leave a comment and and I will add it to the table.

Ampicillin-  	Beta-lactam-transpepsidase-Amphotericin B-cholesterol-Carbenicillin-peptidyl transferase-translation-Chloramphenicol-acetyltransferase--Erythromycin-Macrolide-ermC methyltransferase-Kanamycin-Aminoglycoside-initiation complex frame-shift-Kanamycin phosphotransferase-Gentamycin-Nystatin-Inhibits DNA dependent RNA polymerase-Streptomycin-Prevents aminoacyl tRNA from binding to 30S sub-unit-tetracyline-TetR-TN10

About the author: Nick Oswald
I started Bitesize Bio on a Macbook on my kitchen table in 2007 while in my 7th year of working as a molecular biologist in biotech. My aim was to share the know-how that I had acquired from the school of hard-knocks in the lab, so that others could learn from my mistakes and small victories. Nowadays my mission is to facilitate the gathering of hardcore know-how from whole spectrum of bioscientists and share it here on Bitesize Bio to create a super-mentor that any bioscientist can turn to for much-needed guidance.
