一种抗肽基脯氨酰基顺反异构酶D-IgG抗体的检测试剂盒

By developing an anti-peptidyl prolyl cis-trans isomerase D-IgG antibody detection kit, we have filled the gap in antibody detection for autoimmune nephrotic syndrome, achieved non-invasive etiological detection, simplified the operation, reduced the risk of cross-infection, and provided a basis for early diagnosis.

AI Technical Summary

Technical Problem

The lack of existing technologies for detecting antibodies against peptidyl-prolyl cis-trans isomerase D-IgG makes it difficult to determine the etiology of autoimmune nephrotic syndrome, affecting early diagnosis and treatment.

Method used

A detection kit for anti-peptidyl-prolyl cis-trans isomerase D-IgG antibody was developed. The antibody in serum was detected by immune reaction with the peptidyl-prolyl cis-trans isomerase D antigen protein. Qualitative and quantitative analysis was performed using a solid-phase carrier and labeled antibody.

Benefits of technology

It enables non-invasive detection of autoimmune nephrotic syndrome, clarifies the etiology, reduces patient suffering and economic burden, provides a simple method for large-scale screening, and reduces the probability of cross-infection.

Abstract

本发明提供一种抗肽基脯氨酰基顺反异构酶D‑IgG抗体的检测试剂盒。通过被检测血清样本与靶抗原peptidyl‑prolyl cis‑trans isomerase D(肽基脯氨酰基顺反异构酶D)多肽或其结合片段相接触,发生免疫反应,形成抗原抗体复合物,通过对形成的抗原抗体复合物进行抗肽基脯氨酰基顺反异构酶D‑IgG自身抗体的检测。本发明首次在儿童肾病综合征中鉴定了针对抗肽基脯氨酰基顺反异构酶D‑IgG抗体,并针对该抗体提供了检测试剂盒。为国内外针对与抗肽基脯氨酰基顺反异构酶D‑IgG抗体有关的自身免疫性肾病综合征的鉴别提供一种较好的检测方法。
