摘要:
A precise measurement of the immunological receptor diversity present in a sample is obtained by sequence analysis. Samples of interest are generally complex, comprising more than 102, 103, 104, 105, 106, 107, 108, 109, 1010, 1011, 1012 or more different sequences for a receptor of interest. Immunological receptors of interest include immunoglobulins, T cell antigen receptors, and major histocompatibility receptors. The specific composition of immunological receptor sequence variations in the sample can be recorded and output. The composition is useful for predictive, diagnostic and therapeutic methods relating to the immune capabilities and history of an individual. Such predictions and diagnoses are used to guide clinical decisions.

The present invention provides a method for detecting a chicken Beard trait. Copy number variations of three DNA fragments were found to be present in the chromosomes of bearded chicken number 27, in the physical locations 1702269-1721521 bp, 4470331-4503417 bp, 3578409-3592890 bp; 3 molecular markers were determined, and 3 pairs of primers were designed for said molecular markers; the method of PCR is used for testing the chicken genome to be tested for the described 3 molecular markers; if the three target fragments of the PCR amplification reaction are 3200 bp, 501 bp, and 411 bp, then the detection result is positive; otherwise, the result is negative.

Disclosed are nucleic acid molecules from the genome of Dirofilaria spp. nematodes that contain single nucleotide polymorphisms related to reduced responsiveness of the nematodes to macrocyclic lactones. In one example, the species of Dirofilaria is Dirofilaria immitis (the agent of heartworm in animals). Also disclosed are methods for determining the responsiveness of Dirofilaria spp. nematodes to macrocyclic lactones, methods for selecting a treatment to treat an animal infected with a Dirofilaria spp. nematode, and kits for determining the responsiveness of Dirofilaria spp. nematodes to macrocyclic lactones.

A molecular marker miRNA for sheep breeding. The target gene of the miRNA is FABP6, and the miRNA inhibits the expression of the gene FABP6 in the adipose tissue of sheep.
摘要:
The present invention provides screening kits, compositions, and diagnostic methods for determining whether a subject has a predisposition to, or likelihood of having, a substance use disorder by determining a nucleic acid methylation profile from a biological sample from the subject, wherein a given profile indicates that the subject has a predisposition to a substance use disorder.
摘要:
The present invention provides method of classifying a subject into a necrotizing meningoencephalitis (NME) disease risk group. The method may include assessing the presence of one or more marker (e.g., SNPs or risk loci) in a sample from the subject. For example, detection of the presence of one or more markers that are associated with an increased risk of NME can indicate that the subject should be classified into a risk group.
摘要:
The present invention relates to methods of genotyping for selecting an animal with a desired trait such as the level of monounsaturated fats in muscle tissue, the types and/or ratio of different monounsaturated fats in muscle tissue, marbling, carcass weight, meat quality, speed of finishing, feedlot efficiency and/or consumer preference. In particular the invention relates to methods of selecting an animal with a desired trait by analyzing the M-RIP, NT5M and/or TCAP genes for one or more polymorphisms.
摘要:
The present invention relates to the discovery that the T1R receptors assemble to form functional taste receptors. Particularly, it has been discovered that co-expression of T1R1 and T1R3 results in a taste receptor that responds to umami taste stimuli, including monosodium glutamate. Also, it has been discovered that co-expression of the T1R2 and T1R3 receptors results in a taste receptor that responds to sweet taste stimuli including naturally occurring and artificial sweeteners.Also the present invention relates to the use of hetero-oligomeric taste receptors comprising T1R1/T1R3 and T1R2/T1R3 in assays to identify compounds that respectively respond to umami taste stimuli and sweet taste stimuli.
