One of the main objectives of the protocol presented was the maximization of this process for small
amounts of tissue, since one of the problems of genetic studies in molluscs is the scarcity of tissue. All
the data was clustered in five different groups of weights and the mean of concentration, DNA yield
and purity was quantified (Table 2). As can be observed in Table 2, the data demonstrates that the total
genomic DNA yield is optimal in intervals of [0–5] and [5–10] mg, respectively 6887.30 ± 613.72 and
3577.16 ± 490.42 ng·mg−1 (mean ± SE), meaning that with small quantities of tissue it was possible to
obtain the highest yields of genomic DNA representing a prominent feature of this protocol. Moreover,
the same company (i.e., the QuickGene 610) developed a new automatic DNA extraction system that
allows a ten-fold starting amount (compared with the QuickGene 810), so correspondingly bigger
amounts of DNA may be achieved. However, this system permits only the simultaneous handling of
six samples.
