## Hi Jeff

The stain containing "amylase and a mixture of dna from 3 additional =nknown individuals" may be of special interest.. Amylase is an enzyme =hat breaks down starch in saliva. Unlike DNA, it would be =ndetectable after a heavy cleaning since it depends on the quantity of =esidue. If so, it might mean that the fellation involving 3 people =ther than DSK was very recent (even though presidential suite in not =ented out all the time).

" A tube test may also be carried out if amylase is detected (using the =hadebas° Forensic Press test) in an area that exhibits other =taining such as semen, blood or heavy vaginal deposits. The Tube test =s used in two ways; qualitative and quantitative. The qualitative test =elies in the observable colour difference between the positive test =nd a blank whereas the quantitative test makes use of absorbance =pectrophotometry to exactly measure the ?-amylase activity."
