Hi there,
I have made a DNA library for MiSeq using truseq pcr-free dna HT kit (550bp insert). The problem is that at the end of library preparation and pooling, I need at least 2nM of library for denaturation. But I have only 1nM left in 10 ul. So I can not concentrate it more. (quantified by Kapa universal library quantification kit).
My question is that can I modify the protocol by denaturing in following condition
2 μl of 0.5 N NaOH + 8 μl 1 nM DNA library
instead of recommended
5 μl of 0.2 N NaOH + 5 μl 1 nM DNA library
Then I would have 800pM after denaturation and with a final dilution
of 10ul of above + 990ul of HT1
I can possibly load @ 8 pM which is decent.
By this way I wouldn't be exceeding 1mN NaOH in the final solution which is strictly recommended by Illumina but I'm still doubt full. Please let me know if I am right if any body has done/know similar approach.
Motivation: similar modifications in following paper and also some SeqAnswers posts
Improved Protocols for Illumina Sequencing
on page 18.2.22 says that in denaturation step, care should be taken not to exceed 1mM in final solution.
