Biological Activity

Apramycin Sulfate is an aminoglycoside antibiotic that targets the decoding A-site of bacterial 16S ribosomal RNA. By binding to the deep groove of the 16S rRNA, it disrupts translational fidelity, interferes with translocation, and potently inhibits bacterial protein synthesis. Consequently, this target engagement suppresses bacterial cell growth and exerts broad-spectrum antibacterial activity against various Gram-negative and Gram-positive bacterial strains.

FAQ
Q: Why does a DMSO stock precipitate in media/saline?
A: It is caused by unheated aqueous media (supersaturation), local solvent shock, or incorrect mixing sequence.
How to fix it?
  • Preheat media/saline to 37°C.
  • Mix rapidly (pipette/vortex) upon addition.
  • For complex mixes, always add the aqueous phase last.
  • Re-dissolve minor precipitates with a 37°C water bath and sonication (≤30 min).
