title: [Tissue specificity and expression of a human sperm protein's gene BSD-2.4].
abstract: OBJECTIVE
  To investigate the tissue specificity and expression in spermatogenic stage of BSD-2.4 cDNA which might be related with fertility and its sequence was received by GenBank.
  
  
  METHODS
  Dot blot, Northern blot, and in situ hybridization were used.
  
  
  RESULTS
  Northern blot analysis of sixteen human tissues showed that BSD-2.4 cDNA had one transcript only with testis. BSD-2.4 mRNA was detected in germ cells of human testis.
  
  
  CONCLUSIONS
  BSD-2.4 is a testis-specific protein. The cDNA was expressed throughout the stages of the spermatogenic cycle.
