Description
Technical field
The utility model relates to immune detection, is specifically related to active immunity reaction checking device.
Background technology
Luminescence/fluoroimmunoassay technology is because of its high sensitivity, and good stability, and randomness operation in automation equipment, occupy core status, therefore instead of radiating immuning analysis technology rapidly in modern clinic immunological detection method.Immunologic function test reagent and use instrument must be highly merge, and competence exertion optimum performance, reaches best testing result.
The major measure of current optimization and accelerated reaction has: promote temperature to 37 DEG C, extends the reaction time, reactor concussion mixing, rotation mixing etc.Its objective is lifting molecular motion velocities, impel reactant fully to contact, to shorten the time that immune response reaches balance, thus ensure sufficiently high sensitivity.
Detect in analytical instrument work in active immunity, each step to be conducive to most the mode operation of detection reaction, all should to realize detection reaction and maximizes and optimization, to realize best Detection results.
