electroelution combined with recuperation on hydroxyapatite is an
efficient method. This experiment is carried out on acrylamide gel
polymerized into tubes. First of all, prepare a tube containing a gel
filling about the third of the total volume; then add 0.5 ml of
hydroxyapatite washed by the buffer of electrophoresis (SDS, Na P...); cut
the gel containing the band you intend to elute, into small pieces, and
put these pieces onto hydroxyapatite. fter electrophoresis, recuperate
hydroxyapatite and elute the protein using 0.5M NaP, SDS 0.2%, DTT.
