Research Products International Corp G-418 Disulfate 50 mg/ml Solution, 50 Milliliters

G-418 Disulfate, also known as Geneticin, is an aminoglycoside antibiotic derived from Micromonospora rhodorangea. It is widely used in molecular biology and cell culture as a selective agent. G-418 inhibits protein synthesis by targeting the 80S ribosome, blocking translocation. It is commonly used to select genetically modified cells that carry a G-418 resistance gene, typically introduced via plasmid vectors. This allows for the isolation and maintenance of stable transfectants in gene expression, protein production, and cell line development studies. Its selectivity makes it a key tool in genetic engineering.

Protein synthesis inhibitor. Disrupts peptide transfer on ribosomes (acting as an acyl-tRNA analog) causing premature chain termination during translation. Translational inhibitor in prokaryotic and eukaryotic cells in both in vitro and in vivo systems. Inhibits the transport of proteins into the mitochondria in vitro. Reversible inhibitor of dipeptidyl-peptidase II (serine peptidase) and cytosol alanyl aminopeptidase (metallopeptidase). Apoptosis inducer. Inhibits the growth of Gram-positive bacteria, various animal and insect cells. Fungi and Gram-negative bacteria are resistant due to the low permeability to the antibiotic. Antineoplastic agent. Used in cell biology as selective agent in cell culture systems.

AdipoGen Colistin sulfate (USP Grade),Chemical. CAS: 1264-72-8

Colistin sulfate (USP Grade), AdipoGen Life Sciences. Chemical. CAS: 1264-72-8. Formula: 2(C52H98N16O13) . 5(H2SO4) (unspec.). MW: 2801.7. Isolated from Bacillus polymyxa. Very potent polymyxin antibiotic. Has only one amino acid difference compared to polymyxin B. Antimicrobial. Targets the lipopolysaccharide (LPS) of the outer membrane of Gram-negative bacteria. Competitively displaces divalent cations (Ca2+ and Mg2+) from the negatively-charged phosphate groups LPS, causing disruption of the membrane. This increases the permeability of the cell envelope, leakage of cell contents, leading to apoptosis and cell death. Used against multidrug-resistant Gram-negative bacterial infections.

Research Products International Corp Cefsulodin, Sodium Salt, 100 Milligrams

Cefsulodin Sodium Salt is a cephalosporin antibiotic. Cefsulodin inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs). This disruption interferes with the final stages of peptidoglycan synthesis in the bacterial cell wall, leading to structural instability and eventual cell lysis.

Effective against a range of Gram-negative bacteria, it is particularly useful in the isolation and selection of these bacteria in microbiological and research settings. Commonly used in culture media for the growth and identification of specific bacterial strains.

Additionally, it is often employed as a selective agent in culture media to isolate bacteria that are sensitive to this antibiotic. Its inclusion allows for the specific growth of Gram-negative bacteria lacking resistance to cefsulodin.
