Category Description

               Data items in the EXPTL_CRYSTAL_GROW_COMP category record
               details about the components of the solutions that were 'mixed'
               (by whatever means) to produce the crystal.

               In general, solution 1 is the solution that contains the
               molecule to be crystallized and solution 2 is the solution
               that contains the precipitant. However, the number of solutions
               required to describe the crystallization protocol is not limited
               to 2.

               Details of the crystallization protocol should be given in
               _exptl_crystal_grow_comp.details using the solutions
               described in EXPTL_CRYSTAL_GROW_COMP.

Category Example

     1 1  1  'HIV-1 protease'  '0.002 ml'  '6 mg/ml'
    ; The protein solution was in a buffer containing 25 mM NaCl,
      100 mM NaMES/ MES buffer, pH 7.5, 3 mM NaAzide
     1 2 2 'NaCl'         '0.200 ml'  '4    M' 'in 3 mM NaAzide'
     1 3 2 'Acetic Acid'  '0.047 ml'  '100 mM' 'in 3 mM NaAzide'
     1 4 2 'Na Acetate'   '0.053 ml'  '100 mM'
    ; in 3 mM NaAzide. Buffer components were mixed to produce a
      pH of 4.7 according to a ratio calculated from the pKa. The
      actual pH of solution 2 was not measured.
     1 5 2 'water'        '0.700 ml'   'neat'  'in 3 mM NaAzide'
