ATTO 620
ATTO 620 属于红色光谱区域的新一代荧光标记物。 Characteristic features of the label are strong absorption, temperature dependent fluorescence, and high thermal and photo-stability.
In common with most ATTO-TEC-labels, absorption and fluorescence are independent of pH, at least in the range of pH 2 to 11, used in typical applications. ATTO 620 是一种cationic dye. After coupling to a substrate the label carries a net electrical charge of +1
The label is moderately 亲水性. Its fluorescence is excited most efficiently in the range 600 - 630 nm.
