英文摘要 | homogeneous dna hybridization assay based on the luminescence resonance energy transfer (lret) from a new luminescence terbium chelate, n,n,n-1,n-1-[2,6-bis(3'-aminomethyl-1'-pyrazolyl)-4-phenylpyridine]tetrakis(acetic acid) (bpta)-tb3+ (lambda(ex) = 325 nm and lambda(em) = 545 nm) to an organic dye, cy3 (a,. = 548 nm and a,. = 565 nm), has been developed. in the system, two dna probes whose sequences are complementary to the two different consecutive sequences of a target dna are used; one of the probes is labeled with the tb3+ chelate at the t-end, and the other is with cy3 at the 5'-end. labeling of the tb3+ chelate is accomplished via the linkage of a biotin-labeled dna probe with the tb3+ chelate-labeled streptavidin. strong sensitized emission of cy3 was observed upon excitation of the tb3+ chelate at 325 run, when the two probe dnas were hybridized with the target dna. the sensitivity of the assay was very high compared with those of the previous homogeneous-format assays using the conventional organic dyes; the detection limit of the present assay is about 30 pm of the target dna strand. |
