  • Publication number: 20250092470
    Abstract: Provided herein are methods for detecting and discriminating bacteria and fungal species by nucleic acid amplification, then hybridization analysis on a microarray. Primer pairs are used to simultaneously amplify multiple ribosomal Hypervariable regions from the rDNA or rRNA in bacteria and/or fungi as a multiplex amplification reaction, wherein the resulting hypervariable region amplicon mix is analyzed by hybridization to nucleic acid probes that are complementary to unique sequence determinants within those amplified hypervariable regions. The combination of multiplex amplification and microarray hybridization is used for detection and differentiation of specific species within a microbial set relevant to human or animal health or environmental or agricultural analysis, based on simultaneous analysis of the sequence in two or more hypervariable regions, concurrently.

  • Publication number: 20240384359
    Abstract: Provided herein are methods for identifying antibiotic resistance in a subject in need thereof and for detecting drug resistance in a blood-borne pathogenic bacteria. The methods amplify RNA isolated from whole blood in a multiplexed, isothermal nucleic acid sequence-based amplification (NASBA) reaction using at least one isothermal primer pair with nucleotide sequences specific to a drug resistance marker and with a labeled detector probe binding site and a T7 promoter sequence. Amplicons are hybridized to drug resistance marker probes and to a labeled universal detector probe. A signal indicates drug resistance in the blood-borne pathogenic bacteria.

  • Patent number: 12054794
    Abstract: Provided herein is a method for detecting the presence of a COVID-19 virus RNA or other pathogenic respiratory viruses, such as an influenza virus, or other RNA of interest in a sample. Nucleic acids are obtained from the sample and are used as a template in a combined isothermal reverse transcription, RNAse H and isothermal amplification reaction to generate single stranded RNA amplicons containing sequences complementary to fluorescent labeled detector probes. The single-stranded RNA amplicons hybridize to the detector probe and to hybridization probes with sequences complementary to a sequence determinant in the COVID-19 or other virus RNAs. The microarray is imaged to detect fluorescent signals thereby identifying the virus.

  • Publication number: 20220298547
    Abstract: Provided herein are methods for isolating, detecting and analyzing a virus in a sample. Generally, the virus is isolated via centrifuging, incubating, aggregating, and lysing the sample to obtain a crude neutralized lysate. The crude neutralized lysate is analyzed and the virus(es) are detected by performing one of a first polymerase chain reaction (PCR) amplification followed by a second PCR amplification, by an isothermal amplification or by the reverse transcription reaction and the first polymerase chain reaction amplification together utilizing fluorescently labeled primer pairs and hybridizing the resultant fluorescent labeled amplicons to complementary nucleic acid probes.

  • Publication number: 20220136036
    Abstract: The invention relates to methods of treating diseases comprising administering to a subject a composition comprising the recombinant adeno-associated virus (rAAV). The rAAV is produced by a method comprising: obtaining a template DNA sequence containing a [ITR-cargo-ITR] DNA sequence motif; designing a PCR primer pair such that the 3? terminus of both the forward and reverse PCR primers overlap only about the last 2-8 bases of the A/A? ITR sequences and the 5? terminus of both the forward and reverse PCR primers extend into about 20-35 bases of the flanking sequences; performing PCR with cycling parameters comprising a combined annealing/extension step at a temperature greater than 70° C., thereby producing a plurality of amplicon polynucleotides containing the desired [ITR-cargo-ITR] DNA sequence motif; transfecting the amplicon polynucleotides containing the desired [ITR-cargo-ITR] DNA sequence motif into a packaging cell line; and purifying the lysed cells to collect a quantity of rAAV.

  • Publication number: 20220126258
    Abstract: A composition for measuring binding to HLA proteins has a substrate having a surface and a first array of HLA protein spots indirectly attached to the surface of the substrate. Each HLA protein within each spot is entrapped within a matrix that retains the native three-dimensional structure of the HLA protein while the HLA protein is indirectly attached to the surface. Also disclosed is a formulation to link protein to a solid support that has one or more proteins, a matrix, and one or more non-volatile water-soluble protein solvents, solutes, or combination thereof in an aqueous solution. The matrix is a cross-linked Oligo-dT network, a cross-linked Oligo-U network, a protein network having at least one protein, or a combination thereof.
