在為期幾年的研究工作中,Bio-one公司在Lumazone的基礎(chǔ)上,結(jié)合實(shí)驗(yàn)室的特殊需求改造了原有的生物發(fā)光系統(tǒng),來(lái)適應(yīng)光周期研究對(duì)時(shí)間、光照/拍攝的長(zhǎng)時(shí)間工作流程和周期。

Bio-one北京團(tuán)隊(duì)一直關(guān)注于每個(gè)實(shí)驗(yàn)室實(shí)際應(yīng)用中的差異化要求,選擇適合的CCD和軟件適應(yīng)條件的變化。在本系統(tǒng)中,樣本需要長(zhǎng)時(shí)間在暗箱中完成周期性交替的遠(yuǎn)紅光照射和CCD的拍照,如何解決溫度控制是關(guān)鍵點(diǎn);液氮制冷的CCD可以不受環(huán)境高溫的影響,一直維持在正常的工作狀態(tài),極為敏感地捕捉到生物發(fā)光信號(hào)和強(qiáng)度變化。
