designed to detect the transformation events. The
primers MF-1 (5'-TGTGTACTTCAACTGTCTGC
TTAGC-3') and MR-2 (5'-CCCATCTTCTATCCAA
TCTAACCTC-3') were screened to detect the
specificity,
while
the
primers
MF-3
(5'-GAGGTTAGATTGGATAG AAGATGGG-3') and
MR-5 (5'-ATTCAAGAACTCCTT GGAGGTTGT-3')
were screened to verify the cotton genome. PCR
Reaction system was set as: 5 μL 5 × Go
Taq
buffer, 2 μL
dNTP (2.5 mmol/L) each primer 0.5 μL (10 μmol/L),
0.13 μL Go
Taq
(5 U/μL), 1μL Templates (50 ng/μL),
adding ultra-purified water up to total 25 μL. PCR
amplification
procedures
were
as
follows,
Pre-denaturation at 94 for 5min then 35 amplifying
cycles with 94 for 30s, 60
for 30 s, 72
for 30
s),
finally extension at 72 for 7 min.
3.6.2 Sensitivity test
The GM sample DNA solutions with the concentrations
in weight percentage as 10.00% 1.00% 0.50% 0.10%
0.05% and 0% were prepared by using 100 ng/μL
genetically modified cotton samples DNA and 100 ng/μL
non-transgenic cotton DNA to conduct PCR
amplification with the transformation event-specific
primers; the sensitivity of the test-specific primers were
determined by 2.0% agarose gel electrophoresis. PCR
reaction system was as follows, 5 μL 5 × Go
Taq
buffer, 2 μL
dNTP (2.5 mmol/L), each primer 0.5 μL (10 μmol/L),
0.13 μL GoTaq (5U/μL), 1 μL Templates (100 ng/μL),
adding ultra-purified water up to total 25 μL. PCR
amplification
procedures
were
as
follows:
Pre-denaturation at 94 for 5
min then 35 amplifying
cycles with 94 for 30
s, 60 for 30 s, 72
