4 results about "Membranous nephropathy" patented technology

The application discloses a urine small extracellular vesicle PLA2R1 membrane protein detection method for distinguishing membranous nephropathy, and belongs to the technical field of biomedical detection. The detection method comprises the following steps: preparing an anti-CD63 antibody surface fixed plasmonic metasurface sensing chip to directly capture small extracellular vesicles in urine; preparing an anti-PLA2R1 antibody modified biofunctionalized gold nanoparticle complex to specifically combine with the PLA2R1 membrane protein on the surface of the small extracellular vesicles; detecting the reflection spectrum of the chip after antibody fixation and gold nanoparticle combination through a spectrometer with an integrated optical fiber probe; calculating the resonance wavelength shift amount; measuring the expression level of the PLA2R1 membrane protein; and realizing accurate distinction of healthy people, membranous nephropathy gray area and confirmed patients. The non-invasive detection method is simple in operation and rapid in detection, the sensitivity and the specificity are improved by means of the gold nanoparticle signal amplification effect, and is suitable for large-scale clinical screening and early diagnosis.

The application relates to the technical field of disease diagnosis, and particularly relates to application of CEACAM21 as a serum marker in diagnosis of membranous nephropathy. Based on the marker, risk stratification and treatment decision of the membranous nephropathy can be carried out, and the application has significant clinical significance.
