Amphotericin B (FUNGIZONE®) Solution 250 µg/mL
400-104

Amphotericin B is one of the earliest compounds designed to kill fungi. It was developed to help treat fungal infections intravenously. It has since been found to help eliminate fungal contamination in cell cultures as well. Low doses (0.5 to 2.0 μg/mL) are recommended as it is toxic to other eukaryotic cells at higher concentrations.

Ampicillin Powder
400-130P

This beta-lactam antibiotic is an aminopenicillin. Like penicillin, it inhibits bacterial cell wall synthesis by preventing peptidoglycan cross-linking and murein assembly. The presence of an amino group confers greater efficacy against Gram-negative bacteria as compared to penicillin. Ampicillin is commonly used in molecular biology to assay for gene uptake (e.g., plasmid vectors carrying the ampicillin resistance gene).

Blasticidin S HCL Powder
400-165P

Blasticidin, from Streptomyces griseochromogenes, is an antibiotic commonly used in gene selection.

Blasticidin is active against both prokaryotic and eukaryotic. Resistance to blasticidin is conferred by the blasticidin resistance gene from bacillus cereus (bsr). Bsr codes for blasticidin deaminase.

Carbenicillin Powder
400-105P

Carbenicillin is a third-generation analog of penicillin. Like penicillin, it inhibits bacterial cell wall synthesis by preventing peptidoglycan cross-linking and murein assembly. It shows greater efficacy against Gram-negative bacteria as compared to penicillin. It may be useful against some species of Pseudomonas and Serratia, but has not been generally used in mammalian cell cultures. However, plant cell culturists have found this to be a useful prophylactic agent against many organisms, such as Agrobacterium. Recommended concentration in cell culture is 100 mg/L.

G418 Sulfate Powder
400-111P

G418 sulfate, an aminoglycoside antibiotic, is related to gentamicin. G418 is toxic to both prokaryotic and eukaryotic cells. It is used primarily for the selection of eukaryotic expression vectors bearing the related resistance genes. Recommended concentration varies by cell type; in mammalian cells, 400 mg/L is recommended for initial selection, and then reduced to 200 mg/L for culture maintenance.

Ships on blue ice. Store refrigerated at 2 to 8°C
G418 is also known by the trademark Geneticin®, as registered to Invitrogen Corporation.

Gentamicin Sulfate Powder
400-100P

Gentamicin kills Gram-negative and Gram-positive bacteria, and mycoplasma. It works by binding to microbial ribosomes and preventing the initiation of protein synthesis. Gentamicin is very stable in solution and lasts many days in culture. It is generally more effective than streptomycin. This product should be used with caution, as high concentrations can retard cell growth. Recommended concentration in cell culture is 50 mg/L.

It produces oxygen radicals and is preferentially toxic to hypoxic cells. It is used to generate mitotically inactive feeder cells used in cell culture systems, such as mitotically inactive fibroblast used in embryonic stem cell (ESC) systems. Soluble in methanol and water.

Paromomycin Sulfate Powder
400-155P

Paromomycin is an aminoglycoside antibiotic isolated from Streptomyces rimosus. It targets a variety of gram-negative and gram-positive bacteria as well as several protozoan species. It displays activity similar to that of neomycin.

Aminoglycoside antibiotics are composed of amino groups attached to glycosides. They bind the 30s ribosomal subunit, causing misreading of the mRNA sequence and inhibition of translocation. Consequently, protein synthesis is inhibited.

Paromomycin sulfate is freely soluble.
