  • Title: Monoclonal antibody to human sperm acrosomal protein.
    Author: Capková J, Geussová G, Peknicová J.
    Journal: Folia Biol (Praha); 2000; 46(1):55-7. PubMed ID: 10730883.
    Abstract:
    A new monoclonal antibody designated Hs-14 was generated after immunization of BALB/c mice with the acid extract of human sperm. In indirect immunofluorescence Hs-14 mAb binds to the acrosome of permeabilized sperm cells and consequently recognizes some intra-acrosomal protein. Western blotting analysis revealed that under non-reducing conditions the Hs-14 mAb detects a protein with a molecular mass of 220 kDa. Under reducing conditions the Hs-14 recognizes several peptide bands within the range from 55 kDa to 110 kDa. Beside human sperm the antibody positively reacts also with sperm of some other mammalian species. Using Hs-14 mAb it is possible to evaluate the acrosomal integrity of spermatozoa and to reveal sperm pathology.
