| 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. |
| Application: | Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support. |
| 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. Antimicrobial Spectrum: This product acts against both gram-negative and gram-positive bacteria. |
| Disclaimer: | This product is stable in solution at 37°C for 3 days. Stock solutions should be stored at 2-8°C. |
