CruzFluor sm™8，琥珀酰亚胺酯

CruzFluor™sm 8（CFLsm8）系列具有与IRDye 800相似的光谱特性。它们的荧光在pH值为3至11时不受pH值的影响。这些特性使这种新型染料家族对pH敏感的测定更加稳定。在某些情况下，CFLsm7标记的肽和核苷酸比IRDye 800标记的肽和核苷酸显示更强的荧光和更高的光稳定性。与我们的CruzQuench™8（CQ8）配对，可以开发出多种FRET肽和核苷酸来检测蛋白酶和分子信标。具有增强的灵敏度和稳定性。

CruzFluor™ sm 8 (CFLsm8) family has the spectral properties similar to those of IRDye 800. Their fluorescence is pH-independent from pH 3 to 11. These characteristics make this new dye family more robust to pH-sensitive assays. In some cases CFLsm7-labeled peptides and nucleotides exhibit stronger fluorescence and higher photostability than the ones labeled with IRDye 800. In pairing with our CruzQuench™ 8 (CQ8), a variety of FRET peptides and nucleotides can be developed for detecting proteases and molecular beacons with enhanced sensitivity and stability.
