Moreover, antiserum of the cytosol fraction was found to cross-react with the human sperm antigen indicated presence of a common sperm surface antigenicity between these two diversified species. These findings might support and / or hypothesize about the origin and diversification of the vertebrate molecules from its ancestral form (s) from the invertebrates, and basic physiological functions of these ancestral biomolecules including some of the cellular structures plausibly remain the same regardless their structural changes even after evolution. http://precedings.nature.com/documents/3386/version/1 Wed, 01 Jul 2009 19:19:27 UTC Natural Biomolecules from Marine Snail Telescopium telescopium and structure of its sperm: A Phylogenetic Study hdl:10101/npre.2009.3386.1 2009-07-01 Uttam Datta Nature Precedings 2009-07-01T19:19:27Z Manuscript Evolutionary Biology http://creativecommons.org/licenses/by/3.0/ http://precedings.nature.com/documents/3377/version/1 Electrolyte free mediums prepared with soybean lecithin-glycerol,Coenzyme Q10–glycerol and soybean lecithin-Coenzyme Q10-glycerol were inoculated separately into ligated cauda epididymides, equilibrated 2 h at 5 degree centigrade, wrapped with aluminium foils along with testis and freezed at -10 degree centigrade.Spermatozoan characters were evaluated 7 and 21 days after thawing at 38.5 degree centigrade in a water bath for 5 min. Spermatozoan characters were diminished gradually and significantly (P http://precedings.nature.com/documents/3377/version/1 Fri, 26 Jun 2009 19:49:49 UTC Development of a new method to preserve caprine cauda epididymal spermatozoa in-situ at -10 degrees Centigrade hdl:10101/npre.2009.3377.1 2009-06-26 Uttam Datta Nature Precedings 2009-06-26T19:49:49Z Manuscript Biotechnology http://creativecommons.org/licenses/by/3.0/
