CruzFluor sm™2马来酰亚胺

CruzFluor™sm 2（CFLsm2）系列具有类似于荧光素和AlexaFluor®488（AlexaFluor®是Invitrogen的商标）的光谱特性。与荧光素相比，CFLsm2家族具有更强的荧光和更高的光稳定性。此外，它们的荧光在3到11之间不受pH限制。这些特性使这种新染料家族成为荧光素的替代品。与用FITC或FAM标记的肽和核苷酸相比，CFLsm2标记的肽和核苷酸具有更强的荧光性和更高的光稳定性。与我们的CruzQuench™2（CQ2）配合使用，可以开发出多种FRET肽和核苷酸来检测蛋白酶

CruzFluor™ sm 2 (CFLsm2) family has the spectral properties similar to those of fluoresceins and Alexa Fluor® 488 (Alexa Fluor® is the trademark of Invitrogen). Compared to fluoresceins CFLsm2 family has much stronger fluorescence and higher photostability. Additionally their fluorescence is pH-independent from pH 3 to 11. These characteristics make this new dye family a superior alternative to fluoresceins. CFLsm2-labeled peptides and nucleotides exhibit much stronger fluorescence and higher photostability than the ones labeled with FITC or FAM. In pairing with our CruzQuench™ 2 (CQ2), a variety of FRET peptides and nucleotides can be developed for detecting proteases and molecular beacons with enhanced sensitivity and stability. In addition, CFLsm2 has spectral properties, pH dependence and photostability similar to Alexa Fluor® 488, making them excellent replacement to the expensive Alexa Fluor® 488.
