Prepare the following reaction mix: DNA sample (30 μl) • Water (45 μl) • T4 DNA ligase buffer with 10mM ATP (10 μl) • dNTP mix (4 μl) • T4 DNA polymerase (5 μl) • Klenow DNA polymerase (1 μl) • T4 PNK (5 μl) The total volume should be 100 μl. 2. Incubate in the thermal cycler for 30 minutes at 20ºC.

One of the most critical aspects of optimal library preparation is the quality of the DNA to be sequenced. The DNA must first be effectively and consistently sheared into the appropriate fragment size (depending on the sequencing platform) to enable sensitive and reliable NGS results.

DNA shearing is an experimental process used to prepare DNA for analysis or other processing by the use of mechanical instruments to randomly cleave DNA. DNA is sheared to the desired fragment range. For instance, physical shearing can be done by probe sonication and nebulization.

After a certain length, it becomes difficult to identify the actual base or nucleotide. This is because the quality of the base is inversely proportional to the length of the DNA strand. Subdividing longer DNA sequences into smaller fragments before sequencing provides clearer results.

The first step of DNA sequencing in the NGS technology is DNA fragmentation. Samples of purified DNA are sheared into short fragments, using either mechanical methods (e.g., ultrasonication shearing and nebulization) or enzymatic digestion2.

In general, the core steps in preparing RNA or DNA for NGS analysis are: (i) fragmenting and/or sizing the target sequences to a desired length, (ii) converting target to double-stranded DNA, (iii) attaching oligonucleotide adapters to the ends of target fragments, and (iv) quantitating the final library product for ...

The library preparation process involves converting a genomic DNA sample (or cDNA sample) into a library of fragments which can then be sequenced on an NGS instrument. Breakthrough technology in our library prep helps you get to answers in less time.
