产品说明

一般描述

Chemical structure: macrolide

包装

5, 25, 100 g in poly bottle

应用

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.

生化/生理作用

作用机制: 红霉素通过在转肽步骤中抑制延伸起作用,特别是通过结合细菌70S rRNA复合物的50S亚单位来抑制氨酰从A位点到P位点的易位。

抗菌谱:该产品可以抗革兰氏阴性和革兰氏阳性细菌。

注意

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

制备说明

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.
