说明

制霉菌素是一种多烯类抗生素。
化学结构:多烯
制霉菌素被用作真菌膜(麦角固醇结合)成孔剂,并在脂质双层中创建基于制霉菌素/麦角固醇的离子通道。其用途包括防止细胞培养物污染,诱导表达TLR2的THP1细胞分泌白介素(IL)-1、IL-8和肿瘤坏死因子α。本产品推荐用于50 mg/L的细胞培养应用。

一般描述

Nystatin is a polyene antibiotic.
Chemical structure: polyene
 

应用

Nystatin is used as a fungal membrane (ergosterol binding) pore forming agent and to create nystatin/ergosterol based ion channels in lipid bilayers. Its uses include preventing cell culture contamination and inducing interleukin (IL)-1, IL-8, and tumor necrosis factor α secretion in TLR2-expressing THP1 cells. This product is recommended for use in cell culture applications at 50 mg/L.
 

生化/生理作用

作用机制:制霉菌素通过与真菌细胞膜中的麦角甾醇结合,增加膜的渗透性和产生基于制霉菌素/麦角甾醇的离子通道起作用。 它还可作为脂筏抑制剂和膜相关胆固醇。

抗菌谱:制霉菌素可对抗真菌、酵母和霉菌。
 

注意

Nystatin in tissue culture media is stable at 37°C for three days. It is also stable in moderately alkaline media. Solutions and aqueous suspensions begin to lose activity soon after preparation, with heat, light, and oxygen accelerating the decomposition. Aqueous suspensions are stable for 10 minutes when heating to 100°C at pH 7.
 

制备说明

Nystatin is soluble at 28°C in methanol (11.2 mg/mL), ethanol (1.2 mg/mL), carbon tetrachloride (1.23 mg/mL), chloroform (0.48 mg/mL), benzene (0.28 mg/mL), and ethylene glycol (8.75 mg/mL). It is also soluble in DMSO at 5 mg/mL and freely soluble in DMF and formamide. It is not recommended to autoclave or sterile filter solutions of Nystatin. Prepare 50 mg/mL stock suspensions in water and store at -20°C.
 

其他说明

Keep container tightly closed in a dry and well-ventilated place.Store under inert gas. Air and light sensitive.
