Research Products International Corp Streptomycin Sulfate 250 G

Streptomycin Sulfate is an aminoglycoside antibiotic that inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, disrupting the initiation complex and leading to misreading of mRNA. This interference prevents proper translation and inhibits bacterial growth. Streptomycin is employed in microbiology for selective bacterial isolation and antibiotic sensitivity testing to assess the susceptibility of bacterial strains. Ideal for studying bacterial susceptibility patterns and antibiotic resistance. Its inclusion in culture media aids in selectively isolating bacteria susceptible to this antibiotic.

Invivogen G418 5 G (100 MG/ML)

G418, also known as G418 sulfate and Geneticin, is an aminoglycoside antibiotic similar in structure to gentamicin B1, produced by Micromonospora rhodorangea. G418 blocks polypeptide synthesis by inhibiting the elongation step in both prokaryotic and eukaryotic cells. Resistance to G418 is conferred by the Neomycin resistance gene (neo) from Tn5 encoding an aminoglycoside 3‘-phosphotransferase, APH 3‘ II. Selection in mammalian cells is usually achieved in three to seven days with concentrations ranging from 400 to 1000 µg/ml. Cells that are dividing are affected sooner than those that are not.
