Research Products International Corp Cycloheximide, 25 Grams

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.

Research Products International Corp VALINOMYCIN, STREPTOMYCES FULVISSIMUS, 100 MG

Valinomycin is a naturally occurring cyclic dodecadepsipeptide produced by certain strains of Streptomyces bacteria. It is an ionophore, meaning it facilitates the transport of ions across biological membranes. Specifically, it acts as a potassium ionophore, transporting potassium ions across lipid bilayers. This activity disrupts ion gradients and membrane potentials in cells.

Widely used in research settings as a tool to study ion transport and membrane potential in cells. Its ability to selectively transport potassium ions makes it valuable in experiments exploring cellular electrophysiology. Valinomycin is used to manipulate ion concentrations and study mitochondrial function, as it can alter the electrochemical potential across the inner mitochondrial membrane.

Research Products International Corp Timentin [Ticarcillin Disodium Salt/Potassium Clavulanate Mixture 15:1 Ratio], 1 Gram

Timentin contains two antibiotics: ticarcillin (a penicillin) and clavulanate potassium (a beta-lactamase inhibitor). The combination of ticarcillin and clavulanate enhances the spectrum of antibacterial activity by protecting ticarcillin from degradation by certain bacterial enzymes.

Ticarcillin inhibits bacterial cell wall synthesis, disrupting the integrity of the bacterial cell wall and leading to bacterial cell lysis. Clavulanate potassium works by inhibiting beta-lactamases, enzymes produced by bacteria that can inactivate beta-lactam antibiotics, such as ticarcillin. This combination is effective against a broad spectrum of bacteria, including those producing beta-lactamases.
