The invention discloses a heart-type
fatty acid binding protein content detection kit and a preparation method thereof. The kit disclosed by the invention is formed by a
reagent I and a
reagent II which are mutually independent; the
reagent I comprises the following components of: a biological
buffering agent, a surfactant, a coagulation accelerator, a
preservative, a stabilizing agent, a blocking agent, a chelating agent and water; the reagent II comprises the following components of: latex grains covered by a heart-type
fatty acid binding protein antibody, a biological
buffering agent, a chelating agent, a surfactant, a
preservative, a suspending aid, a sealing agent, a stabilizing agent and water; and the grain diameters of the latex grains covered by the heart-type
fatty acid binding protein antibody are within 90-200nm. The detection kit disclosed by the invention has a series of advantages of good stability, strong specificity, high sensitivity, strong anti-interference capability on rheumatoid factors, good
linear range, simplicity and convenience for detection and operation and the like, and is good for large-scale popularization and application.
