Coppersensor 1

CAS No. : 874748-20-6

MCE 国际站：Coppersensor 1

产品活性：Coppersensor-1 (CS1) 是一种膜透性荧光染料。Coppersensor-1 对 Cu⁺ 具有亲和力，其亲和力在皮摩尔范围，对竞争细胞金属离子具有很高的选择性。Coppersensor-1 作为探针，可以选择性、灵敏地检测包括活细胞在内的生物样品中的铜 (I) 离子 (Cu⁺)。Coppersensor-1 可用于癌症、心血管疾病、神经系统疾病等严重疾病的成像研究。

研究领域：Others

作用靶点：Fluorescent Dye

In Vitro: Guidelines (Following is our recommended protocol. This protocol only provides a guideline, and should be modified according to your specific needs).
A. Preparation of reagent stock solutions for imaging:
1. Prepare a 1 mM stock solution of CS1 (MW 630 g/moL) in DMSO by dissolving 0.63 mg of solid CS1 per milliliter of DMSO solvent.
2. Prepare a 10 mM stock solution of CuCl₂ (MW 134 g/moL) by dissolving 1.34 mg of solid CuCl₂ per milliliter of Millipore water solvent.
B. CS1 labeling of live cells:
1. Imaging experiments with cells will require 1-2 d with cells in culture. Incubate the cells according to your normal protocol.
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.
(Higher concentrations of dye may result in high levels of background fluorescence)
5. Incubate for 5-20 min in the dark at 25 or 37℃.
C. Imaging the CS1-labeled cells:
1. Imageing in standard confocal microscope with 543 nm excitation.
(CS1 can be imaged using any type of fluorescence microscope, including epifluorescence, confocal and multiphoton)
