说明

应用

SQ-NHS contains a reactive N-hydroxysuccinimide group, which allows for coupling with amino groups. When conjugated with proteins, SQ-NHS demonstrates a high quantum yield with an absorption maximum at 640 nm and a nanosecond lifetime. Additionally, in the physiological pH range (6-9), the absorbance, emission, and lifetime of SQ-NHS are pH-independent. It is water insoluble .
