Name:
'_exptl_crystal_grow_comp.details'

Definition:

   A description of any special aspects of the solution component.
   When the solution component is the one that contains the
   macromolecule, this could be the specification of the buffer in
   which the macromolecule was stored. When the solution component
   is a buffer component, this could be the methods (or formula)
   used to achieve a desired pH.

Examples:

'in 3 mM NaAzide' 
;                                 The protein solution was in a buffer
                                  containing 25 mM NaCl, 100 mM NaMES/MES
                                  buffer, pH 7.5, 3 mM NaAzide
;
 
;                                 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.
