Feline Total Thyroxine Quantitative Kit (Fluorescent Immunochromatography Assay of Rare Earth Nanocrystals)（fTT4）
Purpose of Detection
T4 is the main product of thyroid secretion, and the hypothalamic-anterior pituitary-thyroid regulatory system is not complete The missing pieces. It increases basal metabolic rate and plays an important role in the development of all body cells. T4 is stored in thyroid follicles with thyroglobulin and is secreted and released under the regulation of TSH. serum More than 99% of T4 in T4 exist in the form of binding to other proteins. Testing for total T4 in a blood sample can tell if you have abnormal thyroid function.
Detection principle
fTT4 in serum/plasma was quantitatively detected by fluorescence immunochromatography. Basic principle: Fiber nitrate T and C lines were drawn on the dimensional membrane respectively, and T lines were coated with antibody a that specifically recognized fTT4 antigen. The combination pad is sprayed with Another fluorescent nanomaterial labeled antibody b that specifically recognizes fTT4, fTT4 in the sample is first associated with the nanomaterial Labeled antibody b binds to a complex, and then goes topically. The complex competes with T-line antigen A, none Method of capture; In contrast, when fTT4 is not present in the sample, antibody b binds to antigen a when stimulated by light irradiation When, the nanomaterials emit fluorescence signal, and the strength of the signal is inversely proportional to the concentration of fTT4 in the sample.
