Research Products International Corp Anisomycin, 100 MG

Anisomycin is an antibiotic derived from Streptomyces griseolus. It inhibits protein synthesis in eukaryotic cells by blocking the peptidyl transferase activity of the 60S ribosomal subunit. This interference disrupts the elongation phase of protein synthesis, leading to the inhibition of new protein formation.

Anisomycin is widely used as a tool in cell biology and biochemistry to study cellular responses to stress, apoptosis, and various signaling pathways. Its ability to selectively inhibit protein synthesis allows researchers to investigate the role of specific proteins in cellular processes. Anisomycin induces cellular stress and activates various stress response pathways, making it valuable in studies focused on understanding how cells respond to environmental challenges.
