Descripción

General description

Chemical structure: aminoglycoside

Application

Used as a selection agent for cells transformed with kanamycin B (neoR, kanR) resistance gene.

Biochem/physiol Actions

Kanamycin B is an aminoglycoside antibiotic that is the 2-amino,2-deoxy-analog of kanamycin A. Mode of Action: Binds to 70S ribosomal subunit; inhibits translocation; elicits miscoding. Antimicrobial spectrum: Gram-negative and Gram-positive bacteria, and mycoplasm.

Mode of Action: The product acts by binding to the 70S ribosomal subunit, inhibiting translocation and eliciting miscoding.

Mode of Resistance: Aminoglycoside-modifying enzymes (including acetyltransferase, phosphotransferase, nucleotidyltransferase) can alter this antibiotic, preventing its interaction with ribosomes.

Antimicrobial Spectrum: Kanamycin sulfate is effective against gram-negative and gram-postiive bacteria, and mycoplasma.

Preparation Note

Kanamycin sulfate is soluble in water at 50 mg/mL, yielding a clear solution. It is practically insoluble in alcohol, acetone, chloroform, ether and ethyl acetate. A 1% solution in water has a pH of 6.5 to 8.5. Sterile solutions can be prepared by a sterile filtration, through a .2μm filter.

Other Notes

Keep container tightly closed in a dry and well-ventilated place.
