产品描述 Description

Glycogen is a polysaccharide which serves as a form of energy storage in animals and fungi [1]. It is mainly found in the liver and muscle tissues as a secondary long-term energy storage molecule[2]. Glycogen is well-studied in research on cellular metabolism[3], diabetes[4], and athletic performance[5]. In addition, Glycogen is also used as a carrier to help the precipitation and recovery of small amounts of DNA and RNA during nucleic acid extraction, improving the yield and purity of the extracted nucleic acids[6][7].

Glycogen (糖原)是一种多糖,在动物和细菌中作为重要的能量储存分子[1]。它主要存在于肝脏和肌肉组织中,起到次级长期能量储存分子的作用[2]。糖原在细胞代谢[3]、糖尿病[4]和运动表现[5]等领域中被广泛研究。此外,糖原还被用作载体,帮助在核酸提取过程中沉淀和回收少量的DNA和RNA,从而提高提取核酸的产量和纯度[6][7]

实验参考方法 Experimental Reference Method

使用糖原进行核酸沉淀的实验方案
1. 将糖原溶解在无核酸酶的无菌水中,完全溶解后使用无菌无酶的0.22µm滤器过滤除菌,制备浓度为20µg/µL的储存液。储存液分装后冻存在-20℃或-80℃
2. 计算核酸溶液的体积。如果溶液中盐浓度较高,用TE缓冲液(pH 7.0)稀释并充分混合。如果盐浓度较低,可以加入0.1倍体积的3M醋酸钠增加盐浓度。
3. 添加Glycogen至最终浓度为0.05-1µg/µL,以促进核酸沉淀并最大化回收量。
4. 加入2.5-3.0倍体积的预冷乙醇(或1倍体积的异丙醇)并充分混合。将混合之后的溶液在-20°C下保存1小时至过夜,使核酸沉淀。在4°C条件下12,000-15,000g离心10分钟。小心移除上清液,避免扰动核酸沉淀。
5. 用0.5-1mL冷的70%乙醇洗涤沉淀核酸。短暂涡旋之后在4°C以12,000-15,000g再次离心5分钟。 移除上清液,并将沉淀在空气中干燥5-10分钟,以去除残留乙醇。
6. 将核酸沉淀重悬于适量的无核酸酶水或TE缓冲液中,轻轻混合以确保核酸完全溶解。
本方案仅作为实验方案参考,应根据您的具体实验需求进行修改。
