Abstract: An apparatus for holding a test tube in which insulated isothermal polymerase chain reaction is performed includes a heat sink and a tube rack. The heat sink has a main body with a through hole for insertion of the test tube. The through hole has a relatively big diameter section and a relatively small diameter section located below the relatively big diameter section. The tube rack is mounted on the heat sink for insertion of the test tube. The apparatus can ensure that the temperature at the liquid level of the reaction mixture is lower than the temperature suitable for conducting the primer annealing step in the polymerase chain reaction process.

Abstract: An apparatus for generating fluorescence comprises a blue LED emitting a light beam, a filter and a fluorescent material. The filter is arranged in front of the light beam emitted by the blue LED, receives the light beam, and converts the light beam into a filtered light beam having wavelengths of 465-505 nm. The fluorescent material is arranged in one side of the filter, which is opposite to the blue LED, to receive the filtered light beam. The fluorescent material is excited by the filtered light beam to emit fluorescence. The filter is applied to control the wavelength and spectral range of the filtered light beam to achieve the best fluorescence exciting efficiency and prevent from the overlap of the wavelength ranges of the filtered light beam and the fluorescence.

Abstract: An apparatus for holding a test tube in which insulated isothermal polymerase chain reaction is performed includes a heat insulating mount and a heating member. The heat insulating mount has a main body provided with a receiving space for receiving a bottom of the test tube, a lateral channel communicated between the receiving space and an ambient environment, and an upper channel communicated between the receiving space and the ambient environment for insertion of the test tube. The heating member is inserted into the lateral channel for stopping at the bottom of the test tube. The apparatus can minimize the influence caused by the high temperature generated from the heat source on the heat dissipation of the reaction mixture in middle and upper sections of the test tube. The apparatus is suitable for the fluorescent detection of PCR reaction.

Abstract: A method for reverse transcription polymerase chain reaction comprises steps: preparing a capillary, and adding a reverse transcription enzyme into the capillary; and performing a lyophilization process on the RT enzyme contained by the capillary to fabricate the RT enzyme into a lyophilized RT reagent in the capillary. Therefore, a buffer solution, an RNA sample, a polymerase and a primer solution can be added into the capillary to re-dissolve the lyophilized RT reagent and enable a reverse transcription reaction and a polymerase chain reaction of the RNA sample to directly take place inside the capillary, so as to promote convenience and efficiency of experiment.

Abstract: A reaction mixture for a polymerase chain reaction (PCR) includes water, DNA polymerase, deoxyribonucleoside triphosphates (dNTPs), tris(hydroxymethyl)aminomethane hydrochloride (Tris-HCl), potassium chloride, magnesium chloride, dithiothreitol (DDT), and an additive agent. The reaction mixture is capable of enhancing the sensitivity and specificity of PCR and increasing the yield of correct nucleic acid sequence copies when being used in PCR.

Abstract: The present invention is about a mycobacterium smegmatis vaccine, a split product of mycobacterium smegmatis. This vaccine has made good use of the adjuvant function of bacterial cellwall and antigenic specificity of tropina which can stimulate the production of cytokine and consists of many immunologically competent CpG fragments of bacteria DNA. Such vaccine is prepared by treating newly-cultured thalli with a physical quassation technique. This vaccine is capable of enhancing normal immune function against TB, promoting the recovery of normal immune function in TB patients with hypofunction, and depressing the immunological responses in TB patients with hyperfunction. It is especially effective in the prevention and treatment of MTB carriers.
