SerumThawing&HeatInactivation
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 of the product and to prevent breakage of the bottles.Remove bottles from the freez......阅读全文

血清[serum]质量决定因素和使用建议
一、关于血清使用的几点建议： 1、血清必须贮存-20℃，如存放于4℃，请勿超过两周，对于某些单位一次无法用完一瓶，可在无菌条件下将其40-45ml分装于无菌50ml离心管中(或血清瓶中)，由于血清解冻时体积会增加10％，必须预留此膨胀体积的空间，否则易发生污染或容器冻裂的情形。 2、一

血清蛋白（serum－protein）琼脂糖凝胶电泳
【原理】 琼脂糖（agarose）是经过挑选，以质地较纯的琼脂（agar）作为原料而制成的。琼脂在化学上是由琼脂糖和琼脂胶组成的复合物。琼脂胶是一含有硫酸根和羟基的多糖，它具有离子交换性质，这种性质会给电泳及凝胶过滤以不良的影响。琼脂糖是直链多糖，它由D－半乳糖和3,6－脱水－L－半乳糖的残基交
