生物活性

FM4-64, a membrane-selective red fluorescent dye, belongs to the FM family of styrylpyridinium dyes. FM4-64 is widely used to study endocytosis and exocytosis, vesicle trafficking and organelle organization in living animal.

体外研究

FM4-64 readily translocates to the nuclear envelope (NE) at physiological temperature where it exhibits enhanced fluorescence when excited at 620-650 nm in contrast to 480-520 nm excitation in the endocytic pathway and in the endoplasmic reticulum (ER). In vitro data indicated that the dye reveals an enrichment of negatively charged lipids, presumably due to local phospholipid synthesis. Dual-excitation imaging of FM4-64 in relation to lamina-associated polypeptide-1-green fluorescent protein during mitosis suggested that the disassembly of NE preserves microscale lipid complexes in the ER.
For studies onplant and fungal cells, FM4-64 is usually preferred to FM1-43 due to its superior brightness, greater contrast, higher photostability, and its red-shifted emission facilitating concomitantuse with the green fluorescent protein (GFP).

  • 1.

    请依序添加每种溶剂: 10% DMSO → 40% PEG300 → 5% Tween-80 → 45% saline

    Solubility: ≥ 1 mg/mL (1.65 mM); Clear solution

    此⽅案可获得 ≥ 1 mg/mL (1.65 mM,饱和度未知) 的澄清溶液。

    以 1 mL ⼯作液为例,取 100 μL 10.0 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中,混合均匀;向上述体系中加⼊ 50 μ L Tween-80,混合均匀;然后继续加⼊ 450 μL ⽣理盐⽔定容⾄ 1 mL。

    请依序添加每种溶剂: 10% DMSO→90%(20% SBE-β-CD in saline)

    Solubility: ≥ 1 mg/mL (1.65 mM); Clear solution

    此⽅案可获得 ≥ 1 mg/mL (1.65 mM,饱和度未知) 的澄清溶液

    以 1 mL ⼯作液为例,取 100 μL 10.0 mg/mL 的澄清 DMSO 储备液加到 900 μL 20% 的 SBE-β-CD ⽣理盐⽔⽔溶液中,混合均 匀。
