 為什么儲存在冰箱中的胎牛血清會出現(xiàn)沉淀?

GIBICO的胎牛血清沒有預(yù)老化，儲存在2-8℃時，血清中的各種蛋白和脂蛋白（如冷凝集素、纖維蛋白原、玻粘連蛋白等）可能聚集而形成沉淀或可見的混濁。這應(yīng)該不會影響血清的質(zhì)量。推薦在-20℃儲存胎牛血清，避免反復(fù)凍融。

建議血清應(yīng)保存在-5℃至-2O℃。然而，若存放于4℃時，請勿超過一個月。若您一次無法用完一瓶，建議您無菌分裝血清至恰當(dāng)?shù)臏缇萜鲀?nèi)，再放回冷凍。

 如何解凍血清才不會使產(chǎn)品質(zhì)量受損?

建議您將血清從冷凍箱取出后，先置于2～8℃冰箱使之融解，然后在室溫下使之全融。但必須注意的是，融解過程中必須規(guī)則地?fù)u晃均勻。

 血清解凍后發(fā)現(xiàn)有絮狀沉淀物出現(xiàn)，該如何處理?

血清中沉淀物的出現(xiàn)有許多種原因，但zui普遍的原因是由于血清中脂蛋白的變性所造成，而血纖維蛋白（形成凝血的蛋白之一）在血清解凍后，也會存在于血清中，亦是造成沉淀物的主要原因之一。但這些絮狀沉淀物，并不影響血清本身的質(zhì)量。若欲去除這些絮狀沉淀物，可以將血清分裝至無菌離心管內(nèi)，以400g稍微離心，上清液即可接著加入培養(yǎng)基內(nèi)一起過濾。我們不建議您以過濾的方法去除這些絮狀沉淀物，因為它可能會阻塞您的過濾膜。IBCO原裝*南美墨西哥源胎牛血清，貨號10437-028，公司只備貨*貨號，所售血清*來源，有售后，用戶可通過產(chǎn)品批號登陸Life查詢真?zhèn)渭跋螺d質(zhì)量證書。
