Highresolutionnegativestaining
High resolution negative staining(From Valentine et al, 1968. Biochemistry 7:2143-52)Rationale: For the highest resolution with negative staining, there should be little or no support film, but some support is necessary to hold the protein. In this method the proteins are supported by a carbon film and "embedded" in a film of uranyl acetate. The film is cast on mica, which provides the cleanest possibl......阅读全文

银染(silver－staining)操作规程
实验原理：在碱性条件下，用甲醛将蛋白带上的硝酸银（银离子）还原成金属银，以使银颗粒沉积在蛋白带上。染色的程度与蛋白中的一些特殊的基团有关，不含或者很少含半胱氨酸残基的蛋白质有时候呈负染。银染的详细机制还不是非常清楚。 试剂：乙醇、冰醋酸、乙酸钠、硫代硫酸钠、硝酸银、碳酸钠、甘氨酸或EDTA.Na
想更健康？别坐着，起来high！
对于大部分上班族、学生党来说，每天工作、学习都是坐着。有研究表明，在觉醒时间为14到15小时的一天里，我们有55％到75％的时间是坐着的。一般而言，连续静坐超过两小时，身体就会出现亚健康的信号。每天累积静坐8小时以上，多项疾病的风险都会明显升高。像葛大爷这样坐（瘫）着很舒服，但是同时你的身体却在
