Coppersensor 1
Based on 32 publication(s) in Google Scholar
Coppersensor-1 (CS1) is a membrane-permeable fluorescent dye. Coppersensor-1 has a picomolar affinity for Cu+ with high selectivity over competing cellular metalions. Coppersensor-1 as a probe, can selective and sensitive detection of copper(I) ions (Cu+) in biological samples, including live cells. Coppersensor-1 can be used for the research of imaging of severe diseases such as cancer, cardiovascular disorders and neurogenerative diseases.

Guide (Following is our recommended protocol. This protocol only provides a guideline, and should be modified according to your specific needs)[1][2].
Cell Labeling::
1. Prepare a reagent stock solution for imaging: Prepare a 1 mM CS1 stock solution in DMSO.
2. One day before imaging, cells are passaged and plated on 18-mm glass coverslips coated with poly-L-lysine (50 μg/mL). Adherent cells for imaging are grown to 50-80% confluency.
3. Remove cells from incubator, and transfer one coverslip into a 35-mm Petri dish containing 3 mL PBS buffer.
4. To the Petri dish, add 15 μL of a 1 mM CS1 stock solution to give a final dye concentration of 5 μM. Mix thoroughly.
5. Incubate for 5-20 min in the dark at 25 or 37°C.
6. Imageing in standard confocal microscope with 543 nm excitation.
(CS1 can be imaged using any type of fluorescence microscope, including epifluorescence, confocal and multiphoton)
