| Abstract: | Spermadhesins are a family of secretory proteins expressed in the male genital tract of pig, horse and bull. Their function and structure have been widely studied, especially those isolated from boar. However, there are no data concerning spermadhesins isolated from buck. Buck seminal plasma was collected and subjected to ion exchange chromatography on DEAE-Sephacel column followed by chromatography in a C18 column coupled to a HPLC system. The purification of the protein was determined by SDS-PAGE and MALDI-TOF analysis exhibiting a molecular mass of 12.5 KDa and showed to be structurally homologous to spermadhesins from boar and stallion. |
