The present invention relates to the detection of a target nucleic acid sequence by a PTOCE (PTO Cleavage and Extension) assay. The present invention detects a target nucleic acid sequence in which the PTO (Probing and Tagging Oligonucleotide) hybridized with the target nucleic acid sequence is cleaved to release a fragment and the fragment is hybridized with the CTO (Capturing and Templating Oligonucleotide) to form an extended duplex, followed by detecting the presence of the extended duplex. The extended duplex provides signals (generation, increase, extinguishment or decrease of signals) from labels indicating the presence of the extended duplex and has adjustable Tm value, which are well adoptable for detection of the presence of the target nucleic acid sequence.

The invention relates to an eight-unit T/R (transmitting/receiving) basic module with a function of S-band multi-beam transceiving duplexing, applicable to large-scaled multi-beam active phased-array radar, especially S-band unified carrier measurement and control communication systems, and belongs to the technical field of microwave and millimeter wave communications. The module runs under the band of 2.0-2.3GHz and comprises an eight-circuit T/R unit, two one-to-eight power dividers, four combiners and a digital control unit. The module runs under the S-band; a double-channel high-suppression duplexer is used to suppress leakage of transmitted signals, a sideband interval of the transmitting band and the receiving band is only 80MHz for a transceiving duplexing system, and the transmitted signals can be prevented from jamming a preamplifier of a receiving branch even when output power of transmitted beams is up to +20dBm (1W).

Conjugates between a minor groove binding molecule, such as the trimer of 1,2-dihydro-(3H)-pyrrolo[3,2-e]indole-7-carboxylate (CDPI₃), and an oligonucleotide form unusually stable hybrids with complementary target sequences, in which the tethered CDPI₃ group resides in the minor groove of the duplex. These conjugates can be used as probes and primers. Due to their unusually high binding affinity, conjugates as short as 8-mers can be used as amplification primers with high specificity and efficiency. MGB conjugation also increases the discriminatory power of short oligonucleotides, providing enhanced detection of nucleotide sequence mismatches by short oligonucleotides. The MGB-conjugated probes and primers described herein facilitate various analytic and diagnostic procedures, such as amplification reactions, PCR, detection of single-nucleotide polymorphisms, gene hunting, differential display, fluorescence energy transfer, hydrolyzable probe assays and others; by allowing the use of shorter oligonucleotides, which have higher specificity and better discriminatory power.
