At the pre-trial she said the DNA on the knife was in the order of a few hundred picrograms and her report said Real Time PCR for samples A-C. (not it wasn't)
DOMANDA – Ma secondo lei era nell’ordine di qualche nanogrammo o quasi al picogrammo?
RISPOSTA – Sì, era nell’ordine di qualche centinaio di picogrammi, questo sì, sulla quantità totale.

Since from the Real Time quantification (never carried out!) she obtained a concentration of “a few hundred picograms of DNA” (GUP, page 178) she took steps to further concentrate the extract in order to obtain a final volume of 10 μl which she would have used for the PCR reaction

At the trial she testified before the defense even got access to her lab work and said she couldn't remember how much DNA was on the knife she was claiming is the murder weapon.<modsnip>
DEFENSE – Attorney Ghirga
QUESTION – One last question precisely in relation to how much emerged, the DNA extraction on the knife, you I believe, had said that you don’t remember how much DNA you extracted from the blade, from the scratches.
ANSWER – No.
QUESTION – Is it possible to check the extraction log?
ANSWER – Yes, one can check.
QUESTION – Is it a number that can be acquired?
ANSWER – Yes.
QUESTION – One can obtain the extraction in the extraction log as you say.
ANSWER – Yes.
QUESTION – But you do not remember, correct, how much DNA you extracted…
ANSWER – One can obtain the true extraction amount from that S.A.L., that one yes.
QUESTION – But you do not remember now?
ANSWER – No, here, no..
QUESTION – Can one acquire this data?
ANSWER – Yes, the data of the extraction, yes.
QUESTION – While you confirm then how much was… how much was the elution and the collection of DNA to do…
ANSWER – Yes, it was concentrated in the first sweep, then it was quantified, and then after that it was re-concentrated to 10 microlitres.
QUESTION – Now, being interested in the exact quantity of DNA extracted from the scratches we can obtain it, let’s say in the court files, is that so?
ANSWER – Yes.
DEFENSE – Attorney Ghirga – Thank you
