Research Products International Corp Gentamicin Sulfate, 25 Grams

Gentamicin Sulfate is an aminoglycoside antibiotic that inhibits bacterial protein synthesis by binding to the bacterial ribosome. This interference disrupts the translation process, leading to the production of faulty proteins and ultimately causing bacterial cell death.

It is frequently 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 gentamicin.

Research Products International Corp Neomycin Sulfate, 25 Grams

Neomycin Sulfate is an antibiotic that is derived from the bacterium Streptomyces fradiae and belongs to the aminoglycoside class of antibiotics. It exhibits broad-spectrum activity against Gram-negative and some Gram-positive bacteria.

In molecular biology, Neomycin Sulfate is commonly used as a selective agent in genetic engineering experiments and cell culture applications. It is often included in growth media or buffers to prevent the growth of bacteria and ensure the purity of cell lines.

Neomycin Sulfate functions by inhibiting protein synthesis in bacteria, leading to cell death. Neomycin Sulfate is also employed in microbiology research.

WARNING! This product can expose you to Neomycin sulfate, 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 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 Hygromycin B Liquid, 1 Vial

Hygromycin B is an antibiotic commonly used in molecular biology and biotechnology. It is derived from the bacterium Streptomyces hygroscopicus and acts as a selective agent in cell culture.

Often used for the selection of cells that have been genetically engineered to express a hygromycin resistance gene. This gene is typically included in plasmids or vectors used in molecular cloning and genetic engineering. Cells that successfully integrate and express the hygromycin resistance gene become resistant to the inhibitory effects of Hygromycin B.

Hygromycin B is available in various forms, including a liquid solution. Liquid solution is commonly used to establish and maintain stable cell lines, especially during the development of transgenic cells and the generation of genetically modified organisms. The liquid form allows for easy incorporation into cell culture media.
