Fetal Bovine Serum Gold 胎牛血清（特级）
勾选需要的规格可一次提交；也可以逐个询价。货号会一并带入询价单。
Q: 请问我们的血清拿到之后还需要热灭活吗？
A: 本司产品出厂之前都经过了灭活处理，所以一般情况下，就不需要再操作一次灭活了。
Q: 解冻后血清中有悬浮物质/絮状沉淀，因怎样处理？
A: 血清中沉淀物的出现有许多种原因，但最普遍的原因是由于血清中脂蛋白的变性所造成,而血纤维蛋白(形成凝血的蛋白之一)在血清解冻后,也会存在于血清中,亦是造成沉淀物的主要原因之一。但这些絮状沉淀物,并不影响血清本身的质量。
去除这些絮状沉淀物,可以将血清分装至无菌离心管内,以400g稍微离心10-15mins去除沉淀。我们不建议以过滤的方法去除这些絮状物,因为它可能会阻塞您过滤膜。建议在使用血清的时候,注意正确的血清解冻步骤,并尽量避免灭活血清及长时间的将血清置于高温环境中。
Q：为什么本司血清看着比较黄，竞品公司血清比较红？
A: 血红蛋白的原因，血红蛋白含量比较高，血清就会比较红，血红蛋白含量较少，所以会比较黄，血清本质是黄的。
