一、什么是CelCradle生物反應(yīng)器
CelCradle生物反應(yīng)器根據(jù)潮汐漲落原理設(shè)計(jì)而成,其中波紋管的壓縮和解壓可使細(xì)胞不斷接觸培養(yǎng)基的營(yíng)養(yǎng)與空氣,提供了一個(gè)低細(xì)胞撕裂、無泡沫、高氧氣飽和度以及高營(yíng)養(yǎng)濃度的細(xì)胞培養(yǎng)環(huán)境。
CelCradle是用于高密度細(xì)胞培養(yǎng)的一款易于使用的經(jīng)濟(jì)型臺(tái)式生物反應(yīng)器,既可以高密度培養(yǎng)細(xì)胞,也可以收集細(xì)胞分泌產(chǎn)物。
二、CelCradle潮汐式工作原理
通過CelCradle細(xì)胞培養(yǎng)瓶底部的波紋管壓縮和解壓,細(xì)胞間歇的暴露在空氣和培養(yǎng)基中,使細(xì)胞充分與培養(yǎng)基和氧氣接觸,和滾瓶的原理類似。
三、CelCradle生物反應(yīng)器產(chǎn)品特點(diǎn)
•大面積高密度貼壁細(xì)胞培養(yǎng)空間
•預(yù)先滅菌、隨時(shí)可用
•一次性使用CelCradle培養(yǎng)瓶,操作簡(jiǎn)單
•低剪切力、低細(xì)胞撕裂、無泡沫以及無氧氣限制高營(yíng)養(yǎng)的細(xì)胞培養(yǎng)環(huán)境
•兼容大多數(shù)無血清培養(yǎng)基
•全細(xì)胞、細(xì)胞組分或細(xì)胞產(chǎn)物的培養(yǎng)和采集功能
四、為什么選擇CelCradle生物反應(yīng)器
1. 簡(jiǎn)便易用的設(shè)計(jì),一次性使用可以節(jié)約空間和人力資源
CelCradle生物反應(yīng)器是一款隨時(shí)可用的一次性生物反應(yīng)系統(tǒng),無需啟動(dòng)時(shí)間及復(fù)雜的學(xué)習(xí)過程.
CelCradle生物反應(yīng)器可放置在6立方英尺CO2培養(yǎng)箱內(nèi),并且可同時(shí)運(yùn)行4個(gè)細(xì)胞培養(yǎng)瓶。 一個(gè)標(biāo)準(zhǔn)CelCradle細(xì)胞培養(yǎng)瓶帶有5.5g BioNoc II載體,可提供15000平方厘米的細(xì)胞培養(yǎng)總面積,培養(yǎng)細(xì)胞數(shù)可達(dá)到4~5 x 109/瓶,相當(dāng)于18至20個(gè)滾動(dòng)式細(xì)胞培養(yǎng)瓶的培養(yǎng)量。
可以通過增加CelCradle培養(yǎng)瓶數(shù)或者使用同為潮汐原理的TideCell生物反應(yīng)器實(shí)現(xiàn)細(xì)胞規(guī)模的擴(kuò)大化生產(chǎn),從而簡(jiǎn)化了培養(yǎng)系統(tǒng)規(guī)模擴(kuò)大的過程以及節(jié)省了開發(fā)過程中所需的支出。
2. 高細(xì)胞產(chǎn)量,特殊的B_H功能促進(jìn)蛋白表達(dá)
一臺(tái)CelCradle生物反應(yīng)器可取代數(shù)百個(gè)培養(yǎng)皿、傳統(tǒng)細(xì)胞培養(yǎng)瓶以及多組細(xì)胞培養(yǎng)滾瓶等等,從而大大縮減生產(chǎn)成本。
該系統(tǒng)不僅可實(shí)現(xiàn)較高的細(xì)胞產(chǎn)量,且這種特殊的B_H功能(增加底部保持時(shí)間)不僅限制了細(xì)胞的過度生長(zhǎng)而且增加了超過3倍的蛋白表達(dá),同時(shí)還可實(shí)現(xiàn)更高的蛋白濃度并在培養(yǎng)過程中節(jié)省培養(yǎng)基。
五、應(yīng)用領(lǐng)域
•哺乳動(dòng)物和昆蟲細(xì)胞培養(yǎng)
•蛋白質(zhì)和病毒生產(chǎn)
•單克隆抗體生產(chǎn)
•蛋白質(zhì)組研究
•藥物研發(fā)
•藥物代謝動(dòng)力學(xué)研究
•基因和細(xì)胞治療研究
