摘要:
The present invention relates to gene and peptide sequences of a diabetes-specific endogenous retrovirus which is derived from type 1 diabetes patients. In particular, the present invention relates to a whole genome of the diabetes-specific variant of endogenous retrovirus (ERV-9) purified from pancreatic tissues of type 1 diabetes (insulin-dependent diabetes mellitus [IDDM]) patients and its genes and peptide and their sequences, which can be used as a diagnosing reagent for type 1 diabetes and as an immunogen. The diabetes-specific retrovirus expressed exclusively in pancreatic beta cells was purified from deceased type 1 diabetes patients. Subsequently, the retroviral gene sequences were determined, and by analyzing the amino acid sequence of the peptide deduced from the gene, 21 domains of the peptide having hydrophilicity and immuno-dominancy were identified. Therefore, the variant gene of the endogenous retrovirus and the peptide deduced from the gene can be effectively used as a diagnosing reagent of autoimmune-antibody for type 1 diabetes and as a vaccine for the variant ERV-9 related diseases.

The present invention relates to a dried composition for hot-start PCR, more precisely a dried composition for hot-start PCR with improved stability and long-term storagability which is characteristically prepared by the steps of preparing a reaction mixture by mixing an aqueous solution containing reaction buffer, MgCl2, 4 types of dNTPs, DNA polymerase with pyrophosphate and pyrophosphatase in a reaction tube; and drying the reaction mixture prepared above, a preparation method of the same and a method for amplifying nucleic acid using the same. The dried composition for hot-start PCR is added with pyrophosphate and pyrophosphatase together before drying, so that it can have improved stability and long-term storagability as well as convenience in use, compared with the conventional compositions for hot-start PCR. Therefore, this composition can be effectively used for hot-start PCR, multiplex PCR or real-time quantitative PCR.

摘要:
A method for isolating a nucleic acid from a biological sample includes applying particulate matter to promote co-aggregation and co-precipitation of insoluble aggregate by directly adding to the biological sample, adding to the biological sample in admixture with a cell lysis buffer, adding to the biological sample treated with a cell lysis buffer, adding to cell lysates in admixture with a buffer for forming denatured protein aggregate; or adding to cell lysates comprising the formed denatured protein aggregate. The particulate matter is selected from the group consisting of a material formed from an element of Ag, Fe, Ti, Al, Sn, Si, Cu, Mo, Ni, W or Zn, an oxide, a carbide, a nitride, a boride and a silicide thereof, and a mixture thereof, a polymer selected from PMMA (Poly Methyl MethAcrylate), polyethylene or polyurethane; and a mixture thereof. The insoluble aggregate comprises denatured protein aggregate and cell debris.

Provided are an apparatus for integrated real-time nucleic acid analysis and a method for detecting target a nucleic acid using the same, and more particularly an integrated real-time nucleic acid analysis for simultaneously performing qualitative analysis or quantitative analysis on genes from various kinds of plural biological samples and a method for detecting target a nucleic acid using the same. The apparatus for integrated real-time nucleic acid analysis and the method for detecting target a nucleic acid using the same according to the present invention, perform tests of various targets required from various samples through a single step promptly and accurately, and thus, can be efficiently used by hospitals or the like needing to rapidly diagnose diseases.
摘要:
Disclosed are a method for isolating a nucleic acid using particulate matter and a composition therefor. The method comprises essentially the steps of adding a lysis buffer and a neutralization buffer to a biological sample sequentially, and centrifuging cell lysates for at least 10 minutes to separate a solution comprising the nucleic acid and insoluble aggregate comprising denatured protein aggregate and cell debris. The particulate matter is added to and participates in co-aggregation and co-precipitation of denatured protein aggregate and cell debris, and co-aggregates and co-precipitates denatured protein aggregate and cell debris within a much shortened time, thereby to shorten the time and to increase the yield for the isolation of a nucleic acid, compared with conventional methods.
