產(chǎn)品簡介:
BODIPY 480/508-Cholesterol(簡稱:Bdp-Chol),CAS NO:878557-19-8,是一種具生物活性和細胞膜滲透性的膽固醇類似物,在C24位偶聯(lián)了一個BODIPY熒光基團。HeLa細胞中,Bdp-Chol與膽固醇標記物-脫氫麥角甾醇(Dehydroergosterol, DHE)共定位;BHK細胞中,Bdp-Chol 從質(zhì)膜運輸進入內(nèi)吞再循環(huán)小泡(ERC)。Bdp-Chol最大激發(fā)和發(fā)射波長分別是480nm和508nm,用于監(jiān)測細胞內(nèi)的固醇攝取和細胞器間固醇通量。

產(chǎn)品使用:
以下是針對細胞樣本的染色方法,僅作參考。用戶需根據(jù)實際染色樣本和染色條件來優(yōu)化。
1、儲存液的制備
將低溫保存的固體平衡至室溫至少20min,低速離心后,于無菌工作臺內(nèi)加入適量有機溶劑(比如:無水高質(zhì)量DMSO)配置成1mM儲存液,根據(jù)單次用量分裝,充入惰性氣體后,≤-20℃避光凍存。
2、工作液的制備
于正式實驗前,用PBS、HBSS、無血清培養(yǎng)基等稀釋儲存液,到所需的工作濃度,比如:0.1-1μM。最佳的工作濃度請參閱文獻或自行設(shè)置梯度濃度進行摸索。工作液必須現(xiàn)配現(xiàn)用。
應(yīng)用示例(來自文獻,僅做參考)
用BODIPY-Cholesterol進行染色,方法如下:BODIPY-Cholesterol溶于DMSO配置1mM儲存液,分裝到玻璃瓶內(nèi),充氮氣,置于-80℃凍存。精子懸液用BODIPY-Cholesterol(0.4 μM)標記,混勻后,37℃孵育10min。通過二步法不連續(xù)梯度等密度Percoll去除多余的染料。精子調(diào)整密度到1×106sperm/mL,孵育2h后進行流式評估。
Representative images of viable (A and B) and non-viable (C) BODIPY-cholesterol labelled boar spermatozoa following 2h in non-capacitating and capacitating conditions. Note that labelling is higher in the apical sperm head than that in the post-equatorial region (indicated with arrows), which is most obvious in sperm that have not undergone capacitation (A). Upon incubation with capacitating conditions, BODIPY-cholesterol fluorescence reduces across the whole sperm head (B), which visually demonstrates the loss of this cholesterol analogue from the plasma membrane during capacitation. In non-viable spermatozoa, as assessed with propidium iodide (PI), BODIPY-cholesterol fluorescence was more intense across the entire sperm head, particularly in the equatorial region (C; indicated with an arrow), demonstrating potential intracellular labelling. Scale bar=10μm.
注意事項:
1. 為了讓化合物更好的溶解,可通過37℃加熱或(和)超聲波水浴中震動片刻來處理。若實驗所需濃度過大甚至達產(chǎn)品溶解極限,請?zhí)砑又軇┲芑蜃孕姓{(diào)整濃度。
2. 為了您的安全和健康,請穿實驗服并戴一次性手套操作。
