说明

一般說明

Cell permeant ester form of FURA 2 (Cat. No. 344900). The active dye is rapidly released in the cell by cytoplasmic esterases. Fluorescent calcium chelator (K_d = 224 nM) that offers 30 times greater fluorescence intensity than QUIN 2 (Cat. No. 551826). Can be used as a probe in many cellular systems, including cardiac myocytes, vascular smooth muscle cells, and medullary collecting tubules. Spectral properties in the presence of low calcium concentrations (excitation max.: 362 nm, emission max.: 512 nm) differ from those during high calcium conditions (excitation max.: 335 nm, emission max.: 505 nm). Note: 1 set = 10 x 100 µg.

Cell-permeable ester form of FURA 2. Note: 1 set = 10 x 100 µg.

PLURONIC^® F-127, PROTEIN GRADE Detergent (Cat. No. 540025, available separately) is a mild, low-toxicity detergent that can aid in the solubilization of FURA 2/AM.
