This invention relates to the field of biodetection technology, disclosing a preservation solution, an
adiponectin detection kit, its preparation method, and its application. The preservation solution comprises
Tris,
trehalose, Tween 20,
sodium caseinate, PVP-10,
Proclin-300, TX-100, surfactant S13, and
glycine. This specific formulation effectively prevents
quantum dot aggregation and maintains
protein activity for a long time. The
adiponectin detection kit is based on
quantum dot
immunofluorescence chromatography technology and includes components such as a sample pad, a release pad, and a
nitrocellulose membrane. The release pad is simultaneously coated with
quantum dot-labeled antibodies and unlabeled detection line antibodies, and the
quantum dot-labeled antibodies are coupled in a
cascade manner of "
quantum dot-
streptavidin-biotinylated
antibody". This invention, through liquid
dialysis linking technology and a unique release pad
antibody premixing process, utilizes the
signal amplification effect of the
biotin system and the principle of homogeneous reaction, significantly improving the sensitivity, accuracy, and
reagent stability of the detection.
