preparation example Construction

[0056] Please refer to Figure 5 , Figure 5 It is a schematic flow diagram of an embodiment of a method for preparing an immunological reagent for multiple detection in the present invention, wherein the method includes steps:

[0057]S510, providing a preset type of first immunoconjugate, which is respectively used to detect different analytes.

[0058] In step S510, the type of the first immunoconjugate corresponds to the type of the detection index, that is, corresponds to the number of items requiring joint inspection. Wherein, the first immunoconjugates of preset types can respectively bind to corresponding antigens, and corresponding indicators have been detected.

[0059] S520. Add first fluorescent markers to each of the first immune conjugates, so that the first fluorescent markers respectively label each of the first immune conjugates.

[0060] In step S520, in order to make different kinds of first immunoconjugates have different fluorescence intensities, each o...

Abstract

The invention discloses a multi-detection immune reagent, a preparation method, a kit, a system and application thereof; the immune reagent comprises a plurality of first immune compositions, and eachfirst immune composition comprises: a solid phase carrier; the first immune conjugate that is used for carrying out specific immune reaction; the first fluorescent marker that is connected to the first immune conjugate, wherein each of the first immune compositions has a different fluorescence intensity. By means of the mode, dependence of the multiple detection process on the types and performance of the magnetic beads can be reduced, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of immune detection, in particular to a multiple detection immune reagent and its preparation method, kit, system and application. Background technique [0002] With the continuous development of immunoassay technology, multiplex immunoassay technology has become a research hotspot because it can effectively improve the detection efficiency. The so-called multiple detection technology is to add a sample to the detection device to obtain the detection results of multiple analytes at the same time. [0003] At present, for multiple immunoassay techniques, immunoconjugates for detecting different analytes are usually coupled to coded microspheres with different fluorescent types or fluorescence intensities, and by classifying the fluorescent types or intensities on the coded microspheres, it can be determined Test results for different analytes. However, the high price of such encoded microspheres greatly lim...
