Originally isolated from the bacterium *Streptomyces alboniger*, the aminonucleoside antibiotic puromycin is primarily known for its potent ability to inhibit protein synthesis in both prokaryotic and eukaryotic cells, a discovery that has made it an indispensable tool for molecular and cellular biology research.

Penicillin-Streptomycin, or Penstrep, was first introduced for use in cell culture in 1955 and has since become one of the most common antibiotic solutions for preventing bacterial contamination. The key to understanding what is the function of penstrep lies in its dual-component composition, which targets a wide range of bacteria.
