運輸和保存
干冰運輸及復(fù)蘇好存活細胞
(1)1mL凍存管包裝干冰運輸,收到后-80度冰箱保存過夜后轉(zhuǎn)入液氮或直接復(fù)蘇,若發(fā)現(xiàn)干冰已揮發(fā)干凈、凍存管瓶蓋脫落、破損及細胞有污染,請立即與我們聯(lián)系。
(2)T25瓶復(fù)蘇的存活細胞常溫發(fā)貨,收到后按照細胞接收后的處理方法操作。
細胞接收后的處理
1)收到細胞后,75%酒精消毒瓶壁將T25瓶置于37℃培養(yǎng)箱放置約2-3h,若發(fā)現(xiàn)培養(yǎng)瓶破損、有液溢出及細胞有污染,請拍照后及時聯(lián)系我們。
2)請在4或5X顯微鏡下確認細胞狀態(tài),同時給剛收到的細胞拍照(10×,20×)各2-3張以及培養(yǎng)瓶外觀照片一張留存,作為售后時收到時細胞狀態(tài)的依據(jù)。
3)貼壁細胞:細胞在37℃培養(yǎng)箱中放置2-3h,顯微鏡下觀察細胞的生長和貼壁情況,有些貼壁細胞在快遞運送過程中會因振動脫落和脫落后成團的情況。若鏡下觀察細胞的生長密度若在60%以下,可去除培養(yǎng)瓶中灌液培養(yǎng)基(若有未貼壁的細胞需要離心回收,重懸打入到原培養(yǎng)瓶中),加入新配制的完全培養(yǎng)基6-8mL,放到細胞培養(yǎng)箱中繼續(xù)培養(yǎng)。若細胞生長密度達70%-80%以上,可以對細胞進行傳代處理。傳代過程中,若因運輸振動脫落的細胞需要離心回收。
4)備注:運輸用的培養(yǎng)基(灌液培養(yǎng)基)不能再用來培養(yǎng)細胞,請換用按照說明書細胞培養(yǎng)條件新配制的完全培養(yǎng)基來培養(yǎng)細胞。 收到細胞后第一次傳代建議T25培養(yǎng)瓶1:2傳代 。
一.培養(yǎng)基及培養(yǎng)凍存條件準備
1) 準備IMDM培養(yǎng)基;優(yōu)質(zhì)胎牛血清,20%;雙抗1%。培養(yǎng)過程中建議使用0.5ug/ml濃度puro維持。
Capan-1 細胞ATCC官網(wǎng)有關(guān)細胞的說明:
Capan-1 cells typically recover very slowly from cryopreservation, and may need more than a week before the cells attach well and grow sufficiently to be subcultured. Unfortunately this is normal for this cell line. It is normal for cultures of Capan-1 to have many cells which remain in suspension, these cells are viable and should be retained by gentle centrifugation and added back to the adherent population (in the same flask). Do not separate the populations (or discard floating cells) because the culture will become too dilute. Patience is the key to culturing these cells. HTB-79 cells grow as adherent patches with an epithelial-like morphology. Cells on the edges of a patch are somewhat elongated, while cells in the center of the patch are cuboidal and small. Growth will be patchy initially and the cells are very small with epithelial-like morphology. Theese cultures only become 80-90% confluent and will begin to detach at that confluence. There are also normally empty spaces in the culture vessels.
2) 培養(yǎng)條件: 氣相:空氣,95%;二氧化碳,5%。 溫度:37攝氏度,培養(yǎng)箱濕度為70%-80%。
3) 凍存液:90%血清,10%DMSO,現(xiàn)用現(xiàn)配。
