Research Products International Corp Cefoperazone, 10 G

Cefoperazone Sodium Salt is a third-generation cephalosporin antibiotic. Cefoperazone inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs). This disruption interferes with the final stages of peptidoglycan synthesis in the bacterial cell wall, leading to structural instability and eventual cell lysis.

Cefoperazone is effective against a broad range of bacteria, both Gram-positive and Gram-negative. Cefoperazone Sodium Salt is often used as a selective agent in culture media to isolate bacteria that are sensitive to this antibiotic. Its inclusion allows for the specific growth of bacteria lacking resistance to cefoperazone.

Research Products International Corp Cycloheximide, 1 Gram

Cycloheximide is a fungal-derived compound used particularly in molecular biology, microbiology, and cell biology. It inhibits protein synthesis in eukaryotic cells by interfering with the translocation step during protein elongation on the ribosome. It binds to the 60S ribosomal subunit and prevents the movement of peptidyl-tRNA from the A-site to the P-site, inhibiting the synthesis of new polypeptide chains.

WARNING! This product can expose you to Cycloheximide, a chemical which is known to the State of California to cause developmental harm. For more information go to www.P65Warnings.ca.gov.
