The Bacteria Counting Kit accurately enumerates bacteria by flow cytometry. The kit includes the SYTO™ BC dye, which is also available separately (Cat No. S34855), a high-affinity nucleic acid stain that easily penetrates both gram-negative and gram-positive bacteria, producing an exceptionally bright green-fluorescent signal. The kit also includes a calibrated suspension of polystyrene microspheres. Signals from both the stained bacteria and the beads are easily detected in the green fluorescence channel and can be distinguished on a plot of forward scatter versus fluorescence. The density of the bacteria in the sample can be determined from the ratio of bacterial signals to microsphere signals in the cytogram.

Any physiological buffer between pH 7.0–8.0, including PBS, can be used to dilute the SYTO dyes for the staining solution.

常见问题解答 (FAQ)

使用Live/Dead BacLight细菌活力和计数试剂盒进行流式细胞术实验时,部分细胞好像同时出现红绿两种信号,这些细胞是已经死亡、仍在存活还是即将死亡?

试剂盒中的绿色染料是细胞通透性核酸染色剂,会标记所有细胞。红色染料不能渗透进细胞,只能对膜受损的细胞(死细胞)进行染色。因此,任何具有红色信号的细胞会被认为是死亡的。您的细胞可能会出现有些只有红色信号,有些有红色和绿色信号,有些只有绿色信号的现象。有时红色染料会置换绿色染料。在任何情况下,红色细胞都是死亡的。

另外,绿色染料可能漏进红色通道。进行单色染色,同时在绿色和红色滤光片下检查确定漏光程度。为了避免这种漏光的情况,请使用低浓度的染料;如果可能的话,使用窄带通滤光片。

如何通过流式细胞术对细菌进行计数?

这里有几种办法。我们有两种荧光试剂盒可用于细菌计数:Live/Dead BacLight Bacterial Viability and Counting Kit(货号L34856);Bacteria Counting kit, for flow cytometry(货号B7277)。另一个选择是Flow Cytometry Sub-micron Particle Size Reference Kit(货号F13839)。

我可以在流式细胞仪上看到哪些细菌参数?

您可以用BacLight Green细菌染色剂(货号B35000)或BacLight Red细菌染色剂(货号B35001)等常规染色剂进行细菌染色。你们可以看到革兰氏特性(货号L7005),细胞存活率(货号L7007、L7012和L13152),细胞计数(货号L34856和B7277)和细胞活力。细胞活力可以通过膜电位法(货号B34950)或代谢法(货号B34954和B34956)测定。

我用计数微珠进行细胞计数,但在散点图上找不到微珠,该怎么办?

首先检查您的阈值,看它是否设置为前向散射。如果是的话,微珠可能被阈值排除。降低阙值设置后,应该就可以显示出您的微珠了。

我可通过流式细胞仪观察细菌和酵母么?

可以。流式细胞仪可用于:

•计数检测:用于流式细胞仪的细菌计数试剂盒(货号B7277)或LIVE/DEAD BacLight细菌活性和计数试剂盒(货号L34856)
•活性/活力检测:LIVE/DEAD BacLight 细菌活性试剂盒(货号 L13152)
•膜电位:BacLight细菌膜电位试剂盒(货号B34950)
•酵母活性/活力实验:用于流式细胞仪(货号L34952)的LIVE/DEAD FungaLight酵母活性试剂盒,FungaLight酵母CFDA, AM/碘化丙啶活力试剂盒(货号F34953)。
