【 摘 要 】

Background: The primo vascular system (PVS) has been difficult to detect due to its small diameter and translucent features of the threadlike network. Thus, contrast-enhancing dyes including Alcian blue, Trypan blue and Janus green B had to be used for finding and taking out PVS from rat and mouse. Objective: Generation of monoclonal antibodies (mAbs) against PVS of rat was intended to use as a detector for PVS and a biological tool for functional study of PVS. Materials and methods: Primo vessel (PV) and Primo node (PN) were isolated from organ surfaces of rat and then their proteins were isolated and injected into mouse as an immunogen. The classical traditional method was applied for production of mAbs against PVS. The various techniques, such as cell fusion, screening of hybridoma, ELISA, Western blotting (WB), immunofluorescence microscopy (IF), and limiting dilution, were used to generate mAbs against PVS. Results: Among 16 mAbs generated, 4 representative mAbs were characterized with their specificities in ELISA, WB, and IF. α-rPVS-m1-1 and α-rPVS-m4-6 had strong binding affinities to PVS in both ELISA and WB but did not show specificities in IF at all. On the contrary, α-rPVS-m3-2 and α-rPVS-m3-4 almost did not respond in WB but had strong binding affinities in ELISA and specificities in IF. Two mAbs stained predominantly at extra cellular matrix and cell membrane of PVS of rat in IF, and they were able to discriminate PVS from blood vessel (BV) and lymphatic vessel (LV). Conclusions: 4 representative mAbs against PVS of rat were characterized by ELISA, WB, and IF. α-rPVS-m3-2 and α-rPVS-m3-4, which had strong specificities in IF, can be used as a tool in discriminating PVS from other similar tissues and in elucidate biological function of PVS.
