AI Technical Summary

Technical Problem

The lack of antibodies that specifically recognize fish Muc5b in current technologies has hindered the research progress on fish mucosal immune defense mechanisms and made it difficult to deeply understand their role in disease development.

Method used

Antigenic epitopes of turbot Muc5b were screened using bioinformatics analysis. After preparation and conjugation with a vector, New Zealand white rabbits were immunized to obtain turbot Muc5b-specific antibodies. Corresponding detection kits were developed, including antigen retrieval solution, blocking solution, labeled antibody and nuclear dye, for the identification and localization of Muc5b-positive mucinous cells.

Benefits of technology

An antibody that can specifically label Muc5b and positive mucus cells in the mucosal tissue of turbot has been successfully prepared, providing a key detection tool for assessing mucus cell density and distribution, evaluating the relationship between mucus secretion and fish health, and supporting research on fish mucosal immunity and disease diagnosis.

Abstract

本发明提供一种抗原表位多肽及其制备的牙鲆黏蛋白Muc5b特异性抗体,通过筛选获得牙鲆Muc5b蛋白的B细胞抗原表位,其氨基酸序列如NDKQRSKQCEDYQVV所示,将该表位与KLH载体蛋白偶联后免疫新西兰大白兔,制备得到兔抗牙鲆Muc5b特异性抗体。该抗体能够特异性识别牙鲆黏膜组织中的Muc5b蛋白及其阳性黏液细胞,为深入探究黏液细胞在牙鲆黏膜免疫应答过程中的功能机制提供了关键检测工具。
