The invention discloses application of serum alpha-non-
red blood cell ghost
protein 1 in preparation of drugs for diagnosing heart light chain
amyloidosis diseases, and belongs to the technical field of biological medicines. The serum SPTAN1
protein is used for preparing the
medicine for diagnosing the heart light-chain
amyloidosis disease, the
medicine is limited to be an
enzyme linked immunosorbent
assay kit, and the kit comprises an
antibody of the SPTAN1
protein and further comprises a pre-coated plate, a standard substance, a
coating buffer solution, a sample
diluent, a confining liquid,
horse radish peroxidase, an eluent and a color developing agent. The concentration of the SPTAN1 protein in the serum is measured through an
enzyme linked immunosorbent
assay kit, and early diagnosis of the heart AL
amyloidosis disease is carried out. The invention provides a novel, efficient and sensitive biomarker, namely the serum SPTAN1 protein, early diagnosis of heart AL amyloidosis is realized by detecting the concentration of the SPTAN1 protein in serum, and the serum SPTAN1 protein has an important clinical application prospect.
