Research Products International Corp Piperacillin, Sodium Salt, 1 Gram

Piperacillin Sodium Salt is a broad-spectrum β-lactam antibiotic. Piperacillin belongs to the class of extended-spectrum penicillins and inhibits bacterial cell wall synthesis. It achieves this by binding to penicillin-binding proteins (PBPs), enzymes involved in the final stages of peptidoglycan synthesis in the bacterial cell wall. This interference results in structural instability and eventual cell lysis.

Piperacillin Sodium Salt may be used for studying antibiotic susceptibility patterns or as a selective agent in culture media to isolate bacteria that are sensitive to this antibiotic.

AG Scientific Inc Kanamycin Sulfate, 5 G

Kanamycin is an aminoglycosidic antibiotic that inhibits growth of gram-positive, gram-negative bacteria and mycoplasmas in cell culture. Kanamycin or kanamycin A is a major component of the antibiotic complex produced by certain strains of Streptomyces kanamyceticus. Kanamycin is supplied in two forms, a crystalline monosulfate monohydrate and a salt with a higher sulfate content. Kanamycin sulfate is obtained by adding sulfuric acid to a solution of the monosulfate and drying using a suitable procedure. Kanamycin sulfate binds to 30S ribosomes causing inhibition of bacterial protein synthesis.CAS Number: 25389-94-0Molecular Weight: 582.58 DaChemical Formula: C18H36N4O11H2SO4Solubility: Soluble in waterStorage Temperature: Room TemperatureResearch or further manufacturing use only, not for food or drug use.
