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. 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.
