Research Products International Corp Penicillin G Sodium Salt [Benzyl Penicillin Sodium Salt], 25 Grams

Penicillin G sodium is the sodium salt form of penicillin G, which is a narrow-spectrum beta-lactam antibiotic. It is one of the earliest and most widely used antibiotics, belonging to the penicillin class of antibiotics.

Penicillin G sodium interferes with bacterial cell wall synthesis. It inhibits the enzyme transpeptidase, which is involved in the cross-linking of peptidoglycan chains in the bacterial cell wall. This disruption weakens the cell wall structure, leading to cell lysis and death.

Also, Penicillin G is effective against a wide range of Gram-positive bacteria, including Streptococcus, Staphylococcus, and some anaerobic bacteria. It is less effective against Gram-negative bacteria.

Often used as a selective agent in culture media to isolate bacteria that are sensitive to this antibiotic. Its inclusion in culture medium allows for the specific growth of bacteria lacking resistance to penicillin G.

Research Products International Corp Spectinomycin Sulfate, 1 Gram

Spectinomycin Sulfate is an antibiotic that belongs to the class of aminocyclitol antibiotics and is effective against a variety of Gram-negative bacteria. It is frequently used as a selective agent in genetic engineering and gene expression studies.

Researchers incorporate Spectinomycin Sulfate into growth media to selectively allow the growth of cells or organisms that have been genetically modified to carry a resistance gene for Spectinomycin. This resistance gene enables the cells to survive and reproduce in the presence of Spectinomycin, while non-transformed cells are inhibited.

Spectinomycin Sulfate is known for its effectiveness against certain antibiotic-resistant strains of bacteria, making it a valuable tool in research. It works by interfering with protein synthesis in bacteria, ultimately leading to cell death.

Research Products International Corp Doxorubicin Hydrochloride, Liquid, 10 Milligrams

Doxorubicin HCl is an anthracycline antibiotic. Doxorubicin works by interfering with the DNA in cells, preventing the synthesis of new DNA and RNA. It does this by intercalating between DNA base pairs, causing breaks in the DNA strands, and inhibiting the activity of topoisomerase II, an enzyme involved in DNA replication.

Ultimately, these actions lead to the inhibition of cell division and cell death.

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.
