SKE品牌的AutoFee是一個(gè)由pH監(jiān)測(cè)驅(qū)動(dòng)的自動(dòng)培養(yǎng)基交換系統(tǒng)。這款產(chǎn)品的設(shè)計(jì)理念是適用于任何生物反應(yīng)器或培養(yǎng)器。

背景
體外細(xì)胞培養(yǎng)的pH監(jiān)測(cè)可提供細(xì)胞代謝過(guò)程的有用信息,對(duì)于確保組織工程過(guò)程的再現(xiàn)性和標(biāo)準(zhǔn)化起著重要作用,進(jìn)而將研究級(jí)別的生產(chǎn)模型轉(zhuǎn)化成臨床應(yīng)用級(jí)別的制造規(guī)模。
當(dāng)培養(yǎng)基在周期性的批次培養(yǎng)中交換時(shí),pH,代謝產(chǎn)物濃度和信號(hào)分子的突變會(huì)嚴(yán)重阻礙培養(yǎng)系統(tǒng)的恒定控制。

AutoFeed is an automatic medium exchanger driven by pH monitoring, designed to easy fit any bioreactor or culture chamber. AutoFeed minimises labour intensive operator handling, reduces contamination risks during manual medium exchange processes and preserves the homeostasis of culture milieu.
For the successful implementation of stem cell culture in bioreactor systems several critical parameters need to be addressed. These include physicochemical variables such as pH, dissolved oxygen, temperature and biochemical input, including the levels of key nutrients and metabolites, or growth factors: Autofeed provide fresh medium through a medium recirculator and mantain a suitable level of key nutrients in the culture. Like others SKE products, the system is highly configurable, customizable and adaptable for almost every bioreactor.
