Chemical structure: macrolide

アプリケーション

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.

生物化学的／生理学的作用

作用機序：エリスロマイシンは、ペプチド転位ステップにおける伸長を阻害することで作用し、特に、細菌の70s rRNA複合体の50sサブユニットに結合することで、A-部位からP-部位へのアミノアシル転位を阻害します。

抗菌スペクトル：本製品は、グラム陰性細菌とグラム陽性細菌の両方に対して作用します。

包装

25g

注意

This product is stable in solution at 37°C for 3 days. Stock solutions should be stored at 2-8°C.

調製ノート

This product is soluble in water at 2 mg/mL, with a 0.067% solution in water yielding a pH of 8.0-10.5. It is also soluble in ethanol at 50 mg/mL, yielding a clear, colorless to faint yellow solution. It is freely soluble in alcohol, acetone, chloroform, acetonitrile and ethyl acetate but forms salts with acids. All solutions should be protected from light.

その他情報

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