Ampicillin sodium salt, white powder, Cell Culture Grade

Supplier: MP Biomedicals
Description: Ampicillin sodium salt is a semi-synthetic derivative of penicillin, active as a broad-spectrum antibiotic. It is inactivated by beta-lactamases and for this reason a beta-lactamase inhibitor should be considered when using ampicillin. Against gram-positive bacteria, ampicillin has a similar mode of action as benzylpenicillin; against gram-negative bacteria, it has a similar mode of action as chloramphenicol and tetracyclines. In E. coli it inhibits cell wall synthesis.

Carbenicillin disodium salt, free flowing powder

Supplier: MP Biomedicals
Description: Semi-synthetic antibiotic related to penicillin. It is a benzyl penicillin derivative with substitution of a-carboxyl group n the benzyl side chain. The product interferes with final cell wall synthesis of susceptible bacteria. It is completely ionized in the blood. Carbencillin disodium is about 50% reversibly protein bound in plasma and its tissue distribution is similar to other penicillins.

Piperacillin Sodium Salt, white powder

Supplier: MP Biomedicals
Description: Piperacillin is a semisynthetic, broad-spectrum ureidopenicillin antibiotic. It is derived from ampicillin. Piperacillin inhibits the last stage of bacterial cell wall synthesis by binding to certain penicillin-binding proteins (PBPs), which results in cell lysis. Cell lysis is mediated by bacterial cell wall autolytic enzymes. Piperacillin may interfere with autolysin inhibitors.
It has been used in pharmacokinetic studies in order to optimize antimicrobial therapy in patients with sepsis. It is used to study piperacillin hypersensitivity reactions and to study multidrug-resistant organisms.

Cefotaxime Sodium Salt ≥95%, off-white powder

Supplier: MP Biomedicals
Description: Cefotaxime is a cephalosporin, which acts by interference of synthesis of peptidoglycan of the bacterial cell wall. Cefotaxime, a cephalosporin antibiotic, is active against both gram-negative and gram-positive bacteria. In addition, cefotaxime blocks the division of cyanobacteria and lower plant organelles/plastids such as the photosynthetic organelles of Glaucophytes and chloroplasts of bryophytes.
Cefotaxime is used for infections of the respiratory tract, skin, bones, joints, urogenital system, meninges, and bloodstream. It generally has good coverage against most Gram-negative bacteria, with the notable exception of Pseudomonas. It is also effective against most Gram-positive cocci except for Enterococcus. It is active against penicillin-resistant strains of Streptococcus pneumoniae. It has modest activity against the anaerobic Bacteroides fragilis. In meningitis, cefotaxime crosses the blood–brain barrier better than cefuroxime.
Cefotaxim inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs) which inhibits the final transpeptidation step of peptidoglycan synthesis in bacterial cell walls. As a result, bacteria lyse due to cell wall autolytic enzymes.
