Long ssDNA Preparation Kit for 1.5kb, Commercial Entities
Cat. No. DS615 C Store RT,-20°C Size 1 kit
Description
The Long ssDNA(Long Single Strand DNA) Preparation Kits (LsODN Preparation Kits) provide a simple and easy method for generation of a long ssDNA (within 1,500 base or within 3,000 base). A long ssDNA prepared by this kit has defined sequence and length as it does not include inside mutation and terminal deletion caused by PCR, exonuclease side reaction, not high-fidelity reverse transcriptase reaction or not high-fidelity synthetic oligonucleotides.
The procedure is almost same as the method to obtain dsDNA fragments. The DNA of interest is cloned into a plasmid. The resulting plasmid harboring the DNA is digested with a pair of two nicking endonucleases or a combination of a nicking endonuclease and a restriction enzyme. The nicked plasmid is denatured by mixing with Denaturing Gel-Loading Buffer and then subjected to agarose gel electrophoresis. The band corresponding to a long ssDNA is excised and extracted with our kit (#DS640) specially designed for this kit.

Features
A long ssDNA (within 1,500 base or within 3,000 base) can be prepared.
A long ssDNA has defined sequence and length.
Simple principle and easy procedure.

Principle
The DNA of interest is cloned into a plasmid using a pair of two nicking endonuclease sites or a combination of a nicking endonuclease site and a restriction enzyme site.
The resulting plasmid harboring the DNA is digested with a pair of two nicking endonucleases or a combination of a nicking endonuclease and a restriction enzyme.
The nicked plasmid is denatured and then subjected to agarose gel electrophoresis.
The band corresponding to a long ssDNA is excised and extracted.

Data
Fig. Long ssDNAs prepared by this kit
A 1.5 kb DNA fragment of interest was cloned between the Nt.BspQI and the Nb.BsrDI sites of pLSODN-1. Similarly, a 3.0 kb DNA fragment of interest was cloned between the Nt.BspQI and the Nb.BsrDI sites of pLSODN-3. The resulting plasmids were digested with Nt.BspQI and Nb.BsrD. The double nicked plasmid was mixed with Denaturing Gel-loading Buffer and heated, then loaded to conventional non-denaturing agarose gel electrophoresis. The band corresponding to a long ssDNA was excised and extracted.
