Co-migration of galectin-3-reactive and immunoreactive spots on 2D electroblots of seminal plasma. Clarified seminal plasma was subjected to 2D immunoblot and galectin-3 lectin blot analysis. Three distinct immunoreactvie spot patterns ~30 kDa/~pI 7, ~50 kDa/~pI 5, and ~40 kDa/~pI 5 were identified by galectin-3 lectin blot analysis. These three distinct galectin-3-reactive spot patterns comigrated with the immunoblot spot patterns for PSA, PAP, and ZAG at their expected apparent molecular weight and pI.
