PubMed Commons is an experimental system of commenting on PubMed abstracts, introduced in October 2013. Comments are displayed on the abstract page, but during the initial closed pilot, only registered users can read or post comments. Any researcher who is listed as an author of an article indexed by PubMed is entitled to participate in the pilot. If you would like to participate and need an invitation, please email, giving the PubMed ID of an article on which you are an author. For more information, see the PubMed Commons FAQ.

Some minor errours in Methods part

We noticed some minor errours of the units described in the last two sentences of the third paragraph under Methods part of this manuscript. The units described in the sentences, "ml", "mM", and "uC" should read as "μl", "μM", and "°C" respectively. The full two sentences, therefore, should read as "In brief, the PCR mixture was prepared in a 20 μl volume with GC PCR buffer I, 0.5 U Ex Taq, 200 μM each of four dNTPs, 0.5 μM each of the primer set and 10 ng template DNA. PCR was carried out for all loci under the following conditions: initial denaturation at 94 °C for 5 minutes, and then 35 cycles of 94 °C for 30 seconds, 63 °C for 30 seconds and 72 °C for 3 minutes, followed by a final extension at 72 °C for 7 minutes [8]."
We do apologize to readers for any misunderstanding caused by these errours.
