The DNA concentration range of 3.5~15 μM is investigated in various experiments for Oligonucleotide structural analysis such as PAGE, Tm, CD etc is much higher than that in physiological conditions. What is the significance of this assay?
Almost all molecular genetic techniques are designed to bring the final result into a region where it can be measured by the user. They are not designed to mimic physiological conditions and almost all would not work at physiological conditions. pcr ,for example, gets quite hot every cycle and could not work without the dna being made single stranded
I agree with you sir, but when you are analyzing the structure of the oligonucleotide sequence which has some biological relevance, then the DNA concentration and other solution conditions matter.
