IRDye QC-1 NHS Ester琥珀酰亚胺活化酯

IRDye QC-1 NHS Ester

IRDye QC-1 is the first non-fluorescent (dark) quencher compatible with a wide range of visible and near-infrared fluorophores (~500-800 nm). It has the widest available quenching range, so you do not need to carefully match the donor's fluorescence spectrum with the acceptor's absorbance. IRDye QC-1 quenches common fluorophores with >97% efficiency1.

IRDye QC-1 stokes shift and wavelength

Energy that is transferred from the donor (Dem) can be emitted at the acceptor's wavelength (Aem), quenching fluorescence.

For more information, see “Spectral Overlap of IRDye QC-1 Absorption with Common Donor Fluorophores” below.

IRDye QC-1 NHS ester can be used for FRET (fluorescence resonance energy transfer) applications such as protease assays. Recently, it has been paired with IRDye 800CW in optoacoustic studies.

　　IRDye QC-1 NHS 酯

　　IRDye QC-1 是一个与各种可见光和近红外荧光团(~500-800 nm)兼容的非荧光(暗)猝灭剂。 它具有宽的可用猝灭范围，因此您无需仔细匹配供体的荧光光谱与受体的吸光度。 IRDye QC-1 以 >97% 的效率淬灭常见的荧光团1。

　　IRDye QC-1 斯托克斯位移和波长

　　从供体 (Dem) 转移的能量可以以受体的波长 (Aem) 发射，从而淬灭荧光。

　　IRDye QC-1 NHS 酯可用于 FRET(荧光共振能量转移)应用，例如蛋白酶分析。 它已与 IRDye 800CW 配对用于光声研究。
