Area of Science:

  • Reproductive Biology
  • Enzymology
  • Biochemistry

Background:

  • Acrosin is a crucial enzyme found in sperm.
  • Efficient purification methods are needed for studying acrosin's function.

Purpose of the Study:

  • To establish a reliable procedure for purifying chicken acrosin.
  • To optimize extraction and purification techniques for chicken acrosin.

Main Methods:

  • Spermatozoal lysis using a French pressure cell.
  • Extraction with 6 M urea.
  • Purification via gel filtration, chromatofocusing, and affinity chromatography.

Main Results:

  • Achieved a 19-fold purification of chicken acrosin with 28% recovery.
  • Identified two major protein bands with proteolytic activity using native electrophoresis.
  • Successfully obtained milligram quantities of purified chicken acrosin.

Conclusions:

  • The described methods provide a viable procedure for chicken acrosin purification.
  • This technique enables the procurement of sufficient acrosin for further research.
  • Optimized extraction and purification enhance the availability of this important enzyme.
