Fura 2 pentapotassium salt

半岛bd体育手机客户端 说明

一般描述

Fura 2 pentapotassium salt (fura-2) is a fluorescent ratiometric Ca²⁺dye. Fura 2 pentapotassium salt (fura-2) helps to estimate the level of cytosolic Ca(²⁺) by determining the emission found at 510 nm after alternating excitation at 340 nm and 380 nm (F340/F380 ratio). Hence, it is considered as the standard for quantitative intracellular calcium measurements.

应用

Cell impermeable fluorescent probe for Ca²⁺.
