Research Products International Corp Mitomycin C, 5 MG

Mitomycin C is a potent antitumor antibiotic. It is derived from Streptomyces caespitosus and exhibits strong cytotoxic properties. It works by cross-linking DNA, inhibiting DNA synthesis, and inducing cell death. Mitomycin C finds applications in molecular biology and cell biology research. It is frequently employed as a DNA cross-linking agent in studies involving DNA damage and repair mechanisms.

Researchers use Mitomycin C to induce DNA adduct formation and study the cellular response to DNA damage. One notable feature of Mitomycin C is its ability to induce DNA cross-links in both dividing and non-dividing cells, making it useful for investigating cellular processes beyond actively dividing cells.

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

Research Products International Corp Amoxicillin Trihydrate, 50 Grams

Amoxicillin is a broad-spectrum, semi-synthetic penicillin antibiotic that is effective against a wide range of bacteria. The trihydrate form of amoxicillin is a crystalline powder that is often used in laboratory settings.
Amoxicillin inhibits the growth of bacteria by interfering with their cell wall synthesis. It is a versatile antibiotic with low toxicity to mammalian cells, making it a valuable tool in maintaining sterile conditions in cell cultures and studying bacterial physiology.

Researchers use amoxicillin to selectively culture bacteria or to treat bacterial infections in cell cultures.

Research Products International Corp Apramycin Sulfate [Nebramycin II], 10 Grams

Apramycin Sulfate is an aminoglycoside antibiotic that inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, preventing the initiation complex formation and leading to misreading of the mRNA. This interference disrupts the translation process and inhibits bacterial growth.

Commonly used in microbiology to selectively isolate bacteria that are sensitive to this antibiotic. It is also used in antibiotic sensitivity testing to determine the susceptibility of bacterial strains. Its resistance genes are used as selectable markers in genetic engineering. Cells expressing the resistance gene can survive and proliferate in the presence of Apramycin, allowing for the selection of transfected or transduced cells.

Apramycin Sulfate is a valuable tool for selective bacterial isolation, antibiotic sensitivity testing, and selecting cells with specific genetic modifications in molecular biology experiments.

Research Products International Corp Gentamicin Sulfate, 10 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.

AG Scientific Inc Tetracycline HCl 25 G

Tetracycline hydrochloride is a hydrochloride salt form of the antibiotic tetracycline. This polyketide antibiotic binds to both the 30S and 50S ribosomal subunits, thus inhibiting proper protein synthesis. Although it is capable of binding to both subunits, the binding at the 30S subunit is more pronounced than that at the 50S.Clinically, tetracycline is used as a broad spectrum antibiotic for a variety of Gram-positive and Gram-negative bacterial infections. Conditions which may indicate for tetracycline administration include upper respiratory infection, typhus fever and rikkettsialpox. It can also be administered to treat severe cases of acne.Tetracycline has played a prominent research role in studies of the efficacy of local antibiotic application in cases of dental trauma. Owing to the fluorescent properties of tetracycline and its ability to bind to bone tissue, this antibiotic is also regularly used in bone histomorphometry studies.
