包含熒光分子貼附在心臟的短DNA序列能夠作為探針，檢測基因變異的DNA序列片斷。

探針中熒光分子位于中央?yún)^(qū)域，比其他探針具有更大的優(yōu)勢，因?yàn)槠渌结樞盘柣瘜W(xué)位于DNA探針的末端。

這些新型探針叫做HyBeacon，是由LGC公司(South West London, UK)研制開發(fā)的，該公司是一家領(lǐng)先的英國分析診斷產(chǎn)品和服務(wù)供應(yīng)商。
 
DNA Probes Have Medical and Forensic Applications
 
Short DNA sequences that contain a fluorescent molecule attached within the heart of the sequence can act as probes to detect sections of DNA sequence with a genetic variation.

The central location of the fluorescent molecule within the probe has considerable advantages over probes that have their signaling chemistry placed at the end of the DNA probe.

These new probes, called HyBeacon, were developed by LGC, a leading UK provider of analytic and diagnostic products and services (South West London, UK).
