10-phenyl-10H,10′H-spiro[acridine-9,9′-anthracen]-10′-one (ACRSA) is one of the few spiro compounds known to exhibit efficient thermally activated delayed fluorescence (TADF). Its bichromophoric structure consists of a weakly-coupled acridine moiety as an electron-donating unit and an anthracenone moiety as an electro-accepting group. These are covalently linked by a spiro-junction in such a way that the respective π systems are orthogonal.
ACRSA is also known as an aromatic ketone-derived green emitter with a relatively small ΔEST of 0.03 eV.

它最初由在德国生物学家罗伯特·科赫手下工作的细菌学家朱利斯·理查德·佩特里(1852-1921)于1887年设计,故又称为“佩特里皿”。
====================
其实就是常见的圆形的上下盖培养皿,你可以看看它的英文,就叫做petri dish,直译过来就叫做——佩特里小碟子——也就是皮氏培养皿

第二,三段为原创手打……第一段为摘抄
如题~
已经基本养好了贴壁的原代细胞了,准备鉴定了,看到好多都在说细胞爬片的问题,我可以不做爬片直接在皿里操作吗?具体需要注意些什么呢?感谢各位大神
ps:大皿和6孔板里细胞密度、培养条件等等都几乎一样。
我看园子里有人提过类似的问题,但还没人给出答案,希望有经验或有想法的战友帮忙分析分析啊~谢谢!
想问下各位大神,本人用皿养的PC-9GR细胞突然有大片飘起,也并没有成团状飘起,求解决方法?
所谓上皿式指的是称量盘在支架上面;而称量盘吊挂在支架下面的为下皿式。
目前使用较为广泛的是上皿式电子天平。
实验需要请问有没有养THP-1细胞的同仁?能否寄一皿我,我在广州南方医科大学,不胜感激!
同学说传代必须是一皿传多皿,一皿传一皿就不算传代~求高手指点~~
传代后5天,依然没有长满,怕影响活力,想传代和冻存,不知这样是否可以??
