Research Products International Corp Meropenem Trihydrate, 1 Gram

Meropenem is a broad-spectrum antibiotic. It is a carbapenem antibiotic that inhibits bacterial cell wall synthesis. It acts by binding to penicillin-binding proteins (PBPs), enzymes involved in the final stages of peptidoglycan synthesis in the bacterial cell wall. This interference leads to structural instability and eventual cell lysis.

Meropenem may be used as a tool to study antibiotic susceptibility patterns of bacteria or as a selective agent in culture media to isolate bacteria sensitive to this antibiotic.

Research Products International Corp Cycloheximide, 5 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 Novobiocin Sodium Salt, 1 Gram

Novobiocin Sodium Salt is an antibiotic that is a member of the coumarin class of antibiotics and is mainly effective against Gram-positive bacteria. In microbiology and molecular biology research, Novobiocin Sodium Salt is used as a selective agent. It inhibits the activity of DNA gyrase, an enzyme involved in DNA replication and repair in bacteria.

Researchers can incorporate Novobiocin Sodium Salt into growth media to selectively allow the growth of cells or organisms that are resistant to Novobiocin, typically due to the presence of specific resistance genes. This chemical has also found applications in studying DNA topology, replication, and transcription in bacteria, making it valuable in molecular biology and genetic research.

Research Products International Corp Puromycin Dihydrochloride, 100 Milligrams

Puromycin Dihydrochloride is a potent antibiotic. It is an amino nucleoside antibiotic that mimics the 3'-end of aminoacyl-tRNA. It enters the ribosomal A site during translation, causing premature chain termination and inhibiting protein synthesis. Puromycin is incorporated into growing polypeptide chains, leading to the release of incomplete and nonfunctional peptides.

Widely used as a tool in cell biology to study protein synthesis and investigate translation processes. Its ability to terminate protein synthesis at the ribosome makes it valuable for various applications, including pulse-chase experiments and the analysis of nascent peptides. Puromycin resistance genes are often used as selectable markers in genetic engineering. Cells expressing the resistance gene can survive and proliferate in the presence of Puromycin, allowing for the selection of transfected or transduced cells.

Research Products International Corp Penicillin G Potassium Salt, 25 Grams

Penicillin G potassium salt is a member of the penicillin class of antibiotics and is effective against a variety of gram-positive bacteria. As a narrow-spectrum antibiotic belonging to the beta-lactam class, it inhibits the synthesis of bacterial cell walls. It interferes with the formation of peptidoglycan, a crucial component of the bacterial cell wall. This weakens the cell wall and leads to the eventual rupture of the bacterial cell.

Penicillin G is effective against a wide range of Gram-positive bacteria, including Streptococcus, Staphylococcus, and some other species. However, it is not effective against Gram-negative bacteria due to their different cell wall structure.

Research Products International Corp VALINOMYCIN, STREPTOMYCES FULVISSIMUS, 50 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.
