材料表面細(xì)胞活性怎么衡量
|
||||
|
各位兄弟姐妹們, (之前發(fā)信問了幾個牛人同學(xué),都沒有回,無意冒犯,但是這個問題還比較急,現(xiàn)在卡著我,所以又發(fā)帖來咨詢一下)請教一下關(guān)于生物細(xì)胞試驗的一個問題,(非生物專業(yè),只在網(wǎng)上搜索過MTT相關(guān)內(nèi)容)望不吝賜教。 我的目標(biāo)是觀測一種材料表面形態(tài)對細(xì)胞的影響。 初步設(shè)計的試驗方案是在實驗組和對照組材料上面分別培養(yǎng)細(xì)胞,一定時間后(24h,48h,72h)對比兩邊細(xì)胞的差異。 現(xiàn)在的問題是 由于不是生物專業(yè),不知道用什么方法來 對比兩組細(xì)胞,甚至不知道培養(yǎng)何種細(xì)胞比較好。 我目前的想法是 1. 用電鏡直接觀看細(xì)胞形態(tài)變化 /粘附 2. 測量活細(xì)胞密度(不知道怎么測) 3. MTT 分析細(xì)胞活性 否麻煩大家給點建議 |

Are u using multipotent cells like hMSCs? if yes, you could try high-content imaging (see the proliferation) and immunofluorescence Staining (see the expression of alkaline phosphatase (ALP), a marker for early osteogenic differentiation) |

ATP analysis could be used to measured the loss in viability because a decrease in ATP production can be linked to a decrease in cell number. Specifically, ATP could be quantified by measuring the light produced through ATP's reaction with a naturally occurring firefly enzyme-Luciferase using a luminometer. The amount of light produced corresponds proportionally to the amount of live cells present in the sample. |

Thank you sir. So the name of this sort of analysis is ' the ATP analysis‘? Are these reactions you mentioned? luciferin + ATP → luciferyl adenylate + PPi luciferyl adenylate + O2 → oxyluciferin + AMP + light But, are these reaction happening in every type of cell like fibroblasts and epithelials, which are likely to be used in my experiments according to articles in this field. |
