Abstract
The invention provides a test tube for immunoassay, which comprises a cover with sealing function and a water absorption functional part.
Description
Technical Field
The invention belongs to the field of medical examination, and particularly relates to improvement of a labeling immunoassay technology.
Background
In the current immunoassay experiment process, different reagents are added before immunoreaction, and after the experiment reaction is finished, a test tube used for the reaction and reaction liquid in the test tube need to be separated. The test tube is repeatedly cleaned, and finally, the liquid is sucked clean, and the immune reagent marked at the bottom of the test tube is measured. Some of them were centrifuged and the supernatant was extracted and then the pellet at the bottom of the tube was measured. The operation steps are complicated, the working strength is high, and the factors influencing the accuracy of the result are also high.
Disclosure of Invention
The invention aims to provide a test tube for immunoassay, wherein more than two kinds of immunological reagents are added in advance to the bottom area in the test tube, wherein the immunological reagents comprise a marking reagent which can be quantitatively measured from the outside of the test tube, the test tube is kept dry, the immunological reaction does not occur, the test tube is completely isolated from the outside after being covered with a cover (or a plug), and a functional area which can absorb water is arranged in the test tube close to the mouth and far away from the bottom. The test tube is now ready for use.
When an immunoassay experiment needs to be carried out, the cover is only required to be opened, a liquid sample to be measured is added to the bottom of the test tube, and then the cover is covered to keep the test tube in a sealing state and the mouth part is upward. The immune response formally begins when the previously added dry immunoreagent encounters the liquid sample.
After the immune reaction is finished, the test tube is just turned upside down, and the liquid in the test tube flows to the water-absorbing functional area to be fixed. The bottom of the test tube can now be measured.
The whole experimental process is simple and efficient, and the reliability of experimental results is high.
Drawings
The invention is further described below with reference to the accompanying drawings:
FIG. 1 is a schematic view of a test tube for immunoassay according to the present invention
1 is the water absorption functional area of the cover, 2 is the cover which is used for sealing the opening of the test tube, and 3 is the bottom of the test tube.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
Claims (4)
1. The invention discloses a test tube for immunoassay, which comprises a test tube body, a cover capable of sealing and an immunoreaction reagent, and is characterized in that a region which is closer to the opening part of the test tube relative to the bottom of the test tube is provided with a water absorption part, and liquid in the test tube can be fixed on the water absorption part so as to carry out optical measurement or radioactive ray measurement on the residual labeled immunoreaction reagent at the bottom of the test tube.
2. The sealing cap of claim 1 can be wrapped around the test tube port or can be inserted into the test tube port.
3. The water absorbing function portion according to claim 1 is located at a distal end with respect to the bottom of the test tube, and may be integrated with the cap or the test tube body.
4. The immunoreagent of claim 1, comprising an antigen, an antibody, a radioactive tracer, and an optical tracer.
