说明

一般描述

Stock solutions should be filter sterilized and stored at 2-8 °C. Stable at 37 °C for 5 days.

Chemical structure: aminoglycoside

应用

Neomycin Trisulfate is produced by Streptomyces containing a minimum of 85% neomycin B. It has been used as a selection agent for prokaryotic cells transformed using the neo selectable marker gene, and to study ototoxic side effects of antibiotics, platelet-derived growth factor responses in certain fibroblasts, and extraction of Nuclear Phosphatidylinositol 4,5-Bisphosphate-Interacting Proteins. It is recommended for use in cell culture applications at 50 mg/L.

生化/生理作用

作用方式：该产品通过和30S以及50S亚基结合，引起错编，抑制蛋白质合成过程的起始和延长。 新霉素也可阻断电压敏感的Ca²⁺ 通道，而不会影响神经元中Na⁺/Ca²⁺逆向转运蛋白。

抗菌谱：新霉素能够作用于革兰氏阳性和阴性细菌。

注意

Stock solutions should be filter sterilized and stored at 2-8°C, and are stable at 37°C for 5 days. A 1 mg/mL neomycin solution in .1 M phosphate buffer, pH 8.0 should be used within 14 days when stored at 0-5°C. Solutions should be protected from light or moisture.

制备说明

Neomycin sulfate is soluble in H₂O at 50 mg/mL, yielding a clear solution.

其他说明

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