We established the Mez' DNA at your purported "1/500" of a grain of salt weighing 5.82 g /cubic gram, was 29200 picograms, which meets your self-reported criterion of being >100 picograms.
Being low copy number, Stef's lab were only able to perform one DNA test on it, and it was a definitively strong DNA profile of Mez, which the prosecution, defense and judges all agreed on (15 allelles; basic legal minimum being 10).
There is no question it is Mez', was on the knife blade of a kitchen knife that had been scrubbed so clean, only about five traces of organic matter could be found, and which the defense expert DNA scientists witnessed Stef performing, as is their legal right and expectation.
There are no two ways about it, the test was valid, came up with a highly significant result and is absolutely positively Mez' DNA profile beyond any doubt at all.
So assuming we are considering the sample from the blade of the knife.
Q. What was the quantity of DNA found when sample 36b was quantified?
A. None detected
So no DNA was detected in sample 36b when it was subject to DNA quantification. None. How many other samples with no detectable DNA were put through for typing?
Q. When questioned in court how much DNA did Steffanoni say was found?
A. A few hundred picograms.
Q. Was this true?
A. No Stefanoni gave false testimony
Q. How did Stefanoni testify the DNA was quantified?
A. Real time PCR
Q. Was this true?
A. No Stefanoni gave false testimony
