  • Title: Lectin histochemistry of rabbit nephron.
    Author: Castagnaro M.
    Journal: Biol Struct Morphog; ; 3(1):20-6. PubMed ID: 2091802.
    Abstract:
    In order to investigate the usefulness of lectin histochemistry to detail nephronal segmentation we used 12 different biotinylated lectins (Con-A, DBA, GS-I, LCA, PNA, PWN, RCA-I, RCA-II, SWGA, SBA, UEA-I, and WGA) and Avidin-Biotin-Peroxidase (ABC) system on formalin-fixed and paraffin-embedded rabbit kidney sections. Each lectin, except UEA-I which did not stain any nephron structure, shows a different staining pattern along the nephron. Con-A, LCA, and RCA-I display a diffuse staining, while BS-I, RCA-II, SWGA, PWN, DBA, SBA and PNA are selective markers for specific nephron tracts. Furthermore, it is possible, according to the WGA binding pattern, to differentiate the convoluted part of the proximal tubule into two parts, named Segment A and Segment B. Lectin histochemistry on formalin-fixed and paraffin-embedded rabbit kidney sections displays a specific binding pattern along the rabbit nephron and shows interesting morphofunctional correlations.
