Alkali Scientific Ampicillin, Sodium Salt, 1 G

Ampicillin Sodium Salt is a broad spectrum beta lactam antibiotic supplied as a high purity powder for laboratory and research applications. It is widely used to inhibit bacterial cell wall synthesis, making it effective against many Gram positive and Gram negative organisms. This antibiotic is commonly utilized in molecular biology workflows, particularly for selective growth of transformed cells carrying ampicillin resistance genes. The powder format allows precise preparation of stock solutions at required concentrations for experimental use. It is also suitable for microbiological assays, culture media supplementation, and general antibacterial studies where consistent and reliable inhibition of susceptible bacteria is required.

Research Products International Corp RPI Cefuroxime, Sodium Salt, 25 Grams

Cefuroxime Sodium Salt is a second-generation cephalosporin antibiotic. Cefuroxime inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs). This interference disrupts the final stages of peptidoglycan synthesis in the bacterial cell wall, leading to structural instability and eventual cell lysis.

Cefuroxime is effective against a wide spectrum of bacteria, both Gram-positive and Gram-negative. In microbiology and research settings, it is sometimes used as a selective agent in culture media to isolate bacteria that are sensitive to this antibiotic. Additionally, Its inclusion allows for the specific growth of bacteria lacking resistance to cefuroxime.
