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.

    In Vitro

    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)

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
