Abstract: The present invention relates to a method for detecting single nucleotide polymorphism (SNP) using a feature that the 5?-flap endonuclease (FEN) activity of DNA polymerase is inhibited when a probe complementarily binds to the end of a polymerase chain reaction (PCR) product. More specifically, the present invention relates to a novel method wherein it was verified that, when a probe used for a real-time PCR complementarily binds to the end site of a PCR product, the 5?-FEN activity of thermostable DNA polymerase to the probe is inhibited, and thus when such a feature is used to make a design such that an SNP site to be detected is located at the 5?-end site of the probe, the 5?-flap formation is induced according to the allele, thereby allowing effective SNP detection.

Abstract: The present invention relates to a method for separating and purifying a lactone compound with an unsaturated alkyl group from a lactone compound with a saturated alkyl group which is an analog thereof. More specifically, the present invention relates to a method for effectively separating a lactone compound with an unsaturated alkyl group such as FK506 at high purity by extraction with a silver ion (Ag+) solution without use of column chromatography.
