Human lipocalin 6 (hLCN6) is a member of the lipocalin family, which is a group of structurally conserved hydrophobic ligand binding proteins, and widely distributed in animal, plant, and bacteria. Specific expression of hLCN6 in the epididymis and localization of this protein on the surface of spermatozoa suggest a role played by hLCN6, which may function as a transporter to carry ligands in the epididymal channel. However, the role of hLCN6 in sperm maturation has been largely unknown due to the lack of effective antibodies. In this study, we report the prokaryotic expression, purification, and refolding of recombinant hLCN6. Purified hLCN6 protein was used to generate monoclonal antibody (mAb) against this protein using conventional hybridoma techniques. The sensitivity and specificity of the anti-hLCN6 mAb were determined based on their activities in enzyme-linked immunosorbent assay and Western blotting analysis using various human tissues. The results showed that the antibody induced by recombinant hLCN6 protein had high sensitivity and specificity. Taken together, the recombinant hLCN6 protein and mAb against this protein obtained from our study provided useful tools for further exploration of the biological functions and molecular mechanism, as well as pathological significance of LCN6 in human.
