SY-21

SY-21 is a fluorescent dye that belongs to the SYBR family of dyes, designed primarily for use in nucleic acid detection. It is particularly effective for DNA and RNA staining due to its high affinity for nucleic acids, emitting a strong green fluorescence upon binding. SY-21 is commonly used in applications such as quantitative PCR (qPCR), gel electrophoresis, and fluorescence microscopy.

This dye is valued for its strong fluorescence signal, low background noise, and excellent sensitivity, making it ideal for accurate and reproducible detection of nucleic acids in a variety of genetic analysis and biological research applications.
