Recovery of genomic dna from remnant extracted seed samples
This disclosure concerns the isolation of nucleic acids (e.g., genomic dna) from plant seed material that has been defatted. In some embodiments, such nucleic acids are of sufficient quality and abundance that they may be used in an amplification-based genetic analysis technique; for example and without limitation, to make selections in a plant breeding program..

Primers with modified phosphate and base in allele-specific pcr
The present invention includes a method of allele-specific amplification, utilizing an allele-specific oligonucleotide, at least partially complementary to more than one variant of the target sequence, but having at least one selective nucleotide complementary to only one variant of the target sequence and incorporating both a nucleotide with a base covalently modified at the exocyclic amino group and a modified phosphate.. .

Lateral flow detection of target sequences
Provided is a sensitive method to specifically detect nucleic acid sequences using a combination of dna replication based signal amplification (e.g., pcr) and lateral flow analyte detection. The disclosed method uses a dual-labeled dna probe complementary to a region of the target dna sequence.

High-sensitivity magnetic resonance imaging nano-contrast agent based on an anionic polymer and cationic polymer ion complex, and a production method therefor
The present invention provides a magnetic resonance imaging nano-contrast agent based on a nanoparticle composite including iron oxide-based nanoparticles encapsulated in a self-assembled composite of anionic poly-gamma-glutamic acid (γpga) and cationic chitosan. The iron oxide-based nanoparticles encapsulated in the composite interact with each other to produce a synergistic effect on the amplification of magnetic resonance signals, and thus have an relatively excellent contrast effect compared to when they exist as single particles..
