FM4-64 (SynaptoRedTM C2) is a styryl dye that stains stably but does not fluoresce in aqueous solution.FM4-64 does not passively diffuse into the plasma membrane bilayer and must be actively transported across the membrane.FM4-64 can be used to study cytotoxicity, cytosolization, and vesicular transport.Cephalexin monohydroxylin monohydroxylin (Cephalexin monohydroxylin) can be used to study cytotoxicity and vesicular transport.

Cell Research | Instructions for use I. Solution preparation 1. Stock solution: Dissolve FM4-64 in DMSO or sterile water to prepare a high concentration stock solution (usually 1–5 mM). 2. Working solution: Dilute the stock solution to the working concentration (usually 1–10 µM) according to the experimental needs, using an appropriate buffer (such as PBS or serum-free medium). Notes: 1) FM4-64 is a membrane-affinity dye, but it cannot penetrate into cells, so it is suitable for labeling cell membranes or vesicle membranes. 2) The dye will degrade under light, so try to avoid light during operation. II. Operation steps 1. Cell experiment 1) Cell preparation: Culture cells to an appropriate density. Wash cells with serum-free medium or PBS before staining to remove residual substances. Staining steps: 2) Add the working solution directly to the cell culture medium and mix gently. 3) Incubate at an appropriate temperature (e.g., 37°C) for 5–30 minutes, which needs to be optimized based on the experiment. 4) Washing: Wash the cells multiple times with an appropriate buffer (e.g., PBS) to remove unbound dye. Optionally, use cold PBS to terminate staining and reduce background signal. 5) Imaging: Observe the sample using a fluorescence microscope. Excitation wavelength: ~515–540 nm. Emission wavelength: ~640–700 nm (red fluorescence signal). 2. Tissue experiments 1) Tissue preparation: Fix and permeabilize tissue sections (if necessary) to enhance dye penetration. 2) Staining steps: Add working solution to tissue sections and incubate for 10–30 minutes. 3) Washing: Wash tissue sections with PBS to remove excess dye. 4) Imaging: Also observe the red fluorescence signal using a fluorescence microscope. |
