SerumThawing&HeatInactivation
Serum Thawing & Heat Inactivation(Chris Cohick from JRH Biosciences catalogue)How to thaw serum:Serum that is stored at -10o C to -40o C is stable for extended periods of time. It is neither necessary or desirable to store serum at -70o C, as it does not prolong the shelf life of the product and will often damage the bottles. Particular care should be taken when thawing material for use to protect the integrity o......閱讀全文

血清[serum]質量決定因素和使用建議
一、關于血清使用的幾點建議： 1、血清必須貯存-20℃，如存放于4℃，請勿超過兩周，對于某些單位一次無法用完一瓶，可在無菌條件下將其40-45ml分裝于無菌50ml離心管中(或血清瓶中)，由于血清解凍時體積會增加10％，必須預留此膨脹體積的空間，否則易發生污染或容器凍裂的情形。 2、一

血清蛋白（serum－protein）瓊脂糖凝膠電泳
【原理】 瓊脂糖（agarose）是經過挑選，以質地較純的瓊脂（agar）作為原料而制成的。瓊脂在化學上是由瓊脂糖和瓊脂膠組成的復合物。瓊脂膠是一含有硫酸根和羥基的多糖，它具有離子交換性質，這種性質會給電泳及凝膠過濾以不良的影響。瓊脂糖是直鏈多糖，它由D－半乳糖和3,6－脫水－L－半乳糖的殘基交
