CountBright Plus 绝对计数微珠是一种经校准的 ∼4 µm 微珠悬浮液，其中封装了可在多种紫外-红外波长范围内激发并可在 385-860 nm 的发射范围内发出明亮荧光的染料。如果流式细胞仪无法提供绝对细胞计数，可使用绝对计数磁珠来帮助确定计数。绝对细胞计数指的是原始样品中的细胞浓度。

•微珠适用于大多数细胞类型，包括人全裂解血，易于使用
•>95% 的单峰可提高准确度
• 紫外-红外激光器激发可扩大发射范围 (385–860 nm)

常见问题解答 (FAQ)

With the CountBright Plus Absolute Counting Beads/CountBright Absolute Counting Beads, instead of a tight cluster of beads on the scatter plot, I am seeing the beads cover a broad area. What is causing this?

Prior to taking an aliquot, make certain to thoroughly mix the beads. This may also be caused if the beads were ever frozen or the stock solution has any microbial contamination.
