    摘要： Methods for multiplex amplification of target nucleic acid sequences using a single pair of primers. Defined sequences are appended to the ends of multiple target sequences as part of the amplification reaction so that no steps in addition to amplification are required. The target sequences with the appended defined sequences need not be isolated prior to amplification. In one embodiment for coamplification of two target sequences, a sequence corresponding to a terminal segment of the first target sequence is appended to one end of the second target sequence and a sequence corresponding to a terminal segment of the second target sequence is appended to one end of the first target sequence. Amplification of the two targets then requires only a single pair of primers. Alternatively, a single defined sequence may be appended to the 5' and 3' ends of any number of selected targets. All such modified target sequences may then be amplified using a single pair of primers which hybridize to the defined end-sequences.

    摘要： Methods for detecting, immobilizing or localizing primer extension products of a Strand Displacement Amplification reaction which are coupled to, and an indication of, amplification of the target sequence. The primer extension products are secondary, target-specific DNA products generated concurrently with SDA of the target sequence and can therefore be used to detect and/or measure target sequence amplification in real-time. In general, the secondary amplification products are not amplifiable and remain inert in the SDA reaction after they are formed without interfering with amplification of the target sequence. The secondary amplification products may be designed or modified to contain special features to facilitate their detection, immobilization or localization.

    摘要： Primers and methods for adapter-mediated multiplex amplification of the IS6110 insertion element of Mycobacterium tuberculosis (M.tb) and the 16S ribosomal gene of Mycobacterium tuberculosis, useful for simultaneously detecting and/or identifying species of the M. tuberculosis complex and other clinically relevant Mycobacterium species. Multiplex Strand Displacement Amplification (SDA) is used in a single amplification reaction which is capable of simultaneously identifying M. tuberculosis and providing a screen for substantially all of the clinically relevant species of Mycobacteria. Also disclosed are methods for adapter-mediated multiplex amplification of multiple target sequences and a single internal control sequence for determination of sample efficacy or quantitation of the targets. In a preferred embodiment, an internal control sequence is included in the amplification reaction and coamplified with the IS6110 and 16S target sequences as an indication of sample amplification activity or to quantitate the initial amount of target sequences in the sample.

    摘要： Presented herein are methods and compositions for generating sequence-specific, secondary amplification products during Loop-mediated Isothermal Amplification (LAMP). Conventional LAMP produces a preponderance of high molecular weight DNA structures concatenated into self-complementary hairpins, which are not amenable to detection by routine probe-based hybridization methods, making multiplex detection of two or more targets or sequence variants in closed-tube formats extremely difficult. Provided herein, for example, are methods for generating secondary LAMP products bearing a fragment of the original target sequence embedded within low-molecular weight products that are devoid of competitive hairpin structures, the lack of which enhances probe-based detection of target sequences. These secondary products can, for example, be produced in real-time, during the LAMP process, and can provide the option of detecting multiple target sequences within a single tube using, e.g., a homogenous, real-time fluorescence format.
