Product Information Related Products Related Paper COA Technical Q&A

Quin-2 is able to bind calcium ions tightly; it is similar to EGTA and binds calcium more tightly than magnesium. Its combination with calcium causes dramatic changes in UV absorption and fluorescence. When combined with calcium, the fluorescence wavelength is longer than that without calcium. When excited by two different wavelengths of light, the ratio of fluorescence intensity of the two different wavelengths tells the concentration ratio relationship of the bonded free calcium ions. The concentration of free Quin-2 can be determined, so the concentration of free calcium ions can also be accurately calculated. Quin-2 can be injected into cells to detect moment-to-moment changes in the concentration of calcium ions in the cells. Quin-2 AM is cell permeable and can be used to study living cells.
