Purifying a protein from whole saliva is not a good idea, as the bacteria
in the mouth are likely to alter the structure.  You should look into
methods for collecting duct saliva.  For example, parotid saliva can be
easily collectd with a suction cup apparatus.  Parotid saliva has a
viscosity similar to that of water.

It is also possible to collect submadibular saliva, but this requires the
fabrication of  specific collectors for each donor.  This material is also
quite viscous.
