Research Products International Corp Apramycin Sulfate [Nebramycin II], 5 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 Trimethoprim, 5 Grams

Trimethoprim is a bacteriostatic antibiotic that inhibits bacterial dihydrofolate reductase, an enzyme involved in the synthesis of tetrahydrofolic acid. This acid is crucial for the production of nucleic acids (DNA and RNA) in bacteria. By blocking this enzyme, trimethoprim disrupts the folate synthesis pathway, leading to the inhibition of bacterial growth.

Trimethoprim is frequently used as a selective agent in culture media to isolate bacteria that are sensitive to this antibiotic. Its presence in the culture medium allows for the specific isolation of bacteria that lack resistance to trimethoprim.

Research Products International Corp Penicillin G Sodium Salt [Benzyl Penicillin Sodium Salt], 100 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.
