3. High-quality DNA synthesis is always available by our highly efficient synthesis conditions and strict QC.

1) Highly efficient synthesis conditions

< Result of our synthesis efficiency test >

18 bases dT crude Theoretical Value Measured Value
Target Yield 84.30% 82.10%
Synthesis Efficiency 99.00% 98.90%

2) Strict QC system

– Polyacrylamide gel electrophoresis (PAGE)

Our synthesized DNA is subject to QC by polyacrylamide gel electrophoresis.
Electrophoresis using polyacrylamide gel is performed for synthesized products to confirm the bands detected according to the purity of products by electrophoresis images as follows.
High quality of products is kept by detecting bands according to the purity and the base length.
Degenerated sequences may become highly conformational.
Some sequences other than degenerated ones may become conformational such as hairpin structure, and the position of band may be fluctuated or plural bands may appear for such sequences.
Modified DNA tends to migrate more slowly than unmodified DNA depend on molecular size of modification base etc., so the position of the band may be higher than expected.


LC-ESI mass spectrometry analysis

LC-ESI-MS check is applied to modified DNA, LC-ESI-MS Reverse-phase cartfidge purification, LC-ESI-MS HPLC purification, & PAGE purificaton products under 50 bases.
