Research Products International Corp Amphotericin, 250 MG

Amphotericin B is a polyene antifungal agent known for its efficacy against a broad spectrum of fungi, including yeast and molds. It functions by binding to the fungal cell membrane, forming pores that disrupt membrane integrity. This disruption leads to the leakage of cellular contents, ultimately causing fungal cell death.

Amphotericin B is commonly used to prevent and treat fungal contamination in cell cultures and microbiological experiments. It is added to growth media to maintain aseptic conditions and protect cell lines from fungal overgrowth.

The antifungal activity of Amphotericin B makes it a valuable tool in maintaining the integrity of cell cultures and ensuring reliable experimental results.

Apexbio Technology LLC Carbenicillin, Disodium Salt(Synonyms: Carbenicillin disodium, Disodium carbenicillin, Carbenicillin sodium salt), 10mM (in 1mL H2O), CAS: 4800-94-6.

Carbenicillin disodium salt (CAS 4800-94-6) is a semi-synthetic -lactam antibiotic commonly employed in biomedical research As a -lactam it inhibits bacterial cell-wall biosynthesis by irreversibly binding and inactivating bacterial transpeptidase enzymes thereby preventing the cross-linking of peptidoglycan layers required for cell wall integrity Carbenicillin is predominantly utilized against gram-negative bacteria although it also retains limited activity toward some gram-positive strains Due to its resistance to -lactamase-mediated degradation carbenicillin can substitute ampicillin for selecting plasmids encoding the bla (ampicillin resistance) gene in bacterial cultures
