Beschreibung

General description

Chemical structure: macrolide

Application

Erythromycin is an antibiotic produced by growth of certain strains of Streptomyces erythreus. This product is composed largely of erythromycin A with small amounts of erythromycins B and C and is recommended for concentration at 100 mg/L. Concentrations between 50 and 200 mg/L have also proven effective in controlling bacterial growth. Erythromycin has been used as a motilin receptor agonist, to block respiratory glycoconjugate secretion in human airways in vitro, and for selecting plasmid-cured and recombinant lactococcus lactis MG1363 strains. [1][2][3].

Biochem/physiol Actions

Mode of Action: Erythromycin acts by inhibiting elongation at the transpeptidation step, specifically aminoacyl translocation from the A-site to P-site by binding to the 50s subunit of the bacterial 70s rRNA complex.

Antimicrobial Spectrum: This product acts against both gram-negative and gram-positive bacteria.

Packaging

10 ml

Other Notes

Keep container tightly closed in a dry and well-ventilated place. Store under inert gas.

Disclaimer

This Erythromycin solution is concentrated at 1 mg/mL in H₂O and is stable in solution at 37°C for 3 days. Stock solutions should be stored at 2-8°C.
