日期:2021-05-17 13:58:05

高靈敏度生物(wu)發光(guang)(guang)成像(xiang)系(xi)(xi)統(tong)——PhenoAIxpert ES是國際上植(zhi)物(wu)表型(xing)成像(xiang)系(xi)(xi)統(tong)商業化鼻(bi)祖德(de)國LemnaTec公司推出的適(shi)用(yong)于(yu)實驗室的植(zhi)物(wu)表型(xing)測量設備。生物(wu)發光(guang)(guang)作為(wei)一(yi)種報告手段(duan)廣(guang)泛應(ying)用(yong)于(yu)基因活性、分子(zi)相(xiang)互作用(yong)或植(zhi)物(wu)與微生物(wu)相(xiang)互作用(yong)等研究領域。高靈敏度生物(wu)發光(guang)(guang)成像(xiang)系(xi)(xi)統(tong)PhenoAIxpert ES是檢測生物(wu)發光(guang)(guang)效(xiao)應(ying)的先進成像(xiang)解(jie)決方案。

本系統采用(yong)(yong)頂(ding)部可(ke)見光(guang)與(yu)高靈敏度(du)主動(dong)冷卻生(sheng)物(wu)(wu)(wu)發光(guang)成(cheng)像鏡頭相(xiang)結合,能(neng)夠從頂(ding)部獲(huo)取小(xiao)(xiao)型(xing)植(zhi)物(wu)(wu)(wu)的(de)(de)生(sheng)物(wu)(wu)(wu)發光(guang)及表型(xing)信息。PhenoAIxpert ES可(ke)對(dui)小(xiao)(xiao)盆植(zhi)株、用(yong)(yong)多(duo)孔板培養的(de)(de)植(zhi)物(wu)(wu)(wu)、多(duo)孔板里的(de)(de)葉圓片或植(zhi)物(wu)(wu)(wu)組織、植(zhi)物(wu)(wu)(wu)的(de)(de)種(zhong)子(zi)(zi)進行(xing)表型(xing)成(cheng)像測(ce)量;同時也可(ke)以對(dui)昆蟲、小(xiao)(xiao)型(xing)動(dong)物(wu)(wu)(wu)或蟲卵對(dui)植(zhi)物(wu)(wu)(wu)的(de)(de)侵害進行(xing)研(yan)究。適用(yong)(yong)于植(zhi)物(wu)(wu)(wu)生(sheng)理(li)(li)(li)學(xue)(xue)(xue)、農業科學(xue)(xue)(xue)、植(zhi)物(wu)(wu)(wu)病(bing)(bing)理(li)(li)(li)學(xue)(xue)(xue)、病(bing)(bing)蟲害防治研(yan)究、遺(yi)傳育種(zhong)、突變株篩選、植(zhi)物(wu)(wu)(wu)形態建模、種(zhong)子(zi)(zi)生(sheng)理(li)(li)(li)學(xue)(xue)(xue)、種(zhong)子(zi)(zi)病(bing)(bing)理(li)(li)(li)學(xue)(xue)(xue)、植(zhi)物(wu)(wu)(wu)脅(xie)迫生(sheng)理(li)(li)(li)學(xue)(xue)(xue)、毒理(li)(li)(li)學(xue)(xue)(xue)等研(yan)究領域。
