Clodronate Liposomes是由海外某研究所開發,利用巨噬細胞的內吞機制,將膜不通透性的氯膦酸(clodronate)帶入細胞內。在巨噬細胞溶酶體磷酸酶的作用下,釋放溶解在脂質體水相中的氯膦酸,并累積在細胞內。當其達到一定濃度時可以誘導巨噬細胞進入凋亡過程,從而達到清除巨噬細胞的功能。
Clodronate Liposomes適用于多種注射方式,如靜脈注射、腹腔注射、皮下注射、鼻內注射等。注射量與小鼠的體重、注射周期、注射方式以及實驗目的有關。

客戶實測:

圖1 使用翌圣 巨噬細胞清除劑,清除腦周巨噬細胞,結果顯示,實驗組的腦周巨噬細胞教對照組下降至約20%。
產品4 ℃保存。冰袋運輸。不能凍存!保質期6個月。
Q:做肝臟巨噬細胞清除需要灌流,還有流式有沒有什么建議?
A:沒有灌注,流式毫無意義,因為巨噬細胞沒有分到,怎么看差異。流式建議檢測F4/80和CD11b。推薦尾靜脈注射,24h后取肝臟,做免疫組化。免疫組化不用灌流。
Q:體內巨噬細胞清除劑空白脂質體對照這個是單室脂質體還是多室脂質體?
A: 多室的。
Q: 巨噬細胞清除劑的濃度是多少?
A: 5 mg/mL。
Q: Clodronate Liposomes 體內巨噬細胞清除劑這個產品的脂質體粒徑是多大?
A: 150 nm~3um。
Q:收到 Clodronate liposomes 后該如何保存 操作?
A:收到氯磷酸脂質體后,如果不能馬上使用,需放置在4℃冰箱。禁止凍存!使用時作為原液使用, 不能進行稀釋。脂質體很容易發生沉淀,建議使用之前輕輕混勻,另外4℃的氯磷酸脂質體不能馬上使用,需要恢復到室溫才能進行注射。
Q:Clodronate liposomes 能否用于體外巨噬細胞清除?
A:產品可以用于體外巨噬細胞的清除,但是這種方法比較適合體內實驗。主要是由于在體外培養過程中,從死亡細胞釋放的氯磷酸或者是從脂質體中“滲漏”出來氯磷酸,會一直存在于培養基中,但是在體內,氯磷酸的半衰期很短,很快就會被腎臟清除。雖然游離的氯磷酸不會進入細胞也不會進入脂質體,但是一旦他們在培養基中積累就會慢慢地進入細胞中。
Q:在靜脈注射 Clodronate liposomes 后動物很快就死亡了,是什么原因?
A:一方面有可能是動物注射了不均一的脂質體懸液。建議在使用之前輕輕搖晃混勻。脂質體在體外一段時間后會發生沉降。如果在很長一段時間內需要一次注射多只動物,那么脂質體便會在注射器中發生沉淀,形成不均一懸液,這樣一來,第一只注射的計量與最后一只注射的計量就會發生明顯的變化。另外一方面有可能是脂質體剛從冰箱取出后,沒有恢復到室溫。
Q:對于清除不同器官或是組織內的巨噬細胞應該注射什么位置,注射劑量多少,注射時間和周期如何確定?
A:這個要涉及到具體的實驗方案設計,建議客戶自行設計實驗方案,我們可以提供給他一些參考文獻或是自行尋找符合自己實驗目的的文獻進行參考。
Q:動物在注射 Clodronate liposomes 后幾天就死亡了?
A:這個可能是操作過程中受到細菌的污染,體內清除巨噬細胞后會增加例如病毒粒子 細菌或者酵母感染的幾率。
Q:靜脈注射 Clodronate liposomes 后大鼠脾臟/肝臟中的 ED1+細胞并沒有完全消失?
A:大鼠中成熟的巨噬細胞呈現ED1和ED2雙陽性,但是有一些沒有吞噬功能的或者吞噬作用小的前體細胞也是 ED1+,但是呈現ED2-。因此,所有 ED2+的細胞都可以被完全清除,但是ED1+的細胞卻只能被部分清除,清除的比率取決于前體/成熟巨噬細胞的比例。
Q:Clodronate liposomes 沒有達到期望的效果?
A:氯磷酸脂質體都是大批量的生產,每批次都會對氯磷酸的濃度以及一些可能的污染物進行檢測,確保無誤后才會銷售給客戶。另外,脂質體容易收到極端溫度的影響。正確的運輸和儲存方式是4~8℃,懸液既不能被凍存,也不能被加熱超過30℃。自收到貨物起,需要在3個月內使用完,不然有可能會影響使用的效果。
Q:在靜脈注射時,能不能增加注射的體積?
A:靜脈注射時需要依據動物的體重,不能超過0.1mL/10mg,但是進行腹腔注射可以適當的增加注射的體積。皮下注射需要根據注射位點的容量進行決定。
Q: 巨噬細胞清除劑,運輸的過程中產品凍上了,還能使用嗎?
A:不能使用。
Q: 巨噬細胞清除劑是陰離子嗎?
A: 是的,陰離子的。
Q: 巨噬細胞清除劑,說明書上5 mg/mL是指藥物的濃度嗎?
A: 是的,是指藥物的濃度。
