摘要:
The present invention relates to primers for PCR amplification comprising abasic parts within the primer sequences and a method for PCR amplification using the same. More precisely, the present invention relates to primers capable of amplifying different templates and having abasic parts complementary to mutated site or polymorphic site of template DNA and a method for PCR amplification comprising the steps of mixing the composition for PCR amplification comprising the primers with nucleic acid template; and performing PCR with the mixture. The primers for PCR amplification of the present invention contain abasic parts not having specific coding information in their nucleotide sequences, so that they can amplify different templates having mutated sites at the same time.

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.

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.
