Do general synthetic Oligo DNAs have phosphate groups at the 5' and 3' ends?
No, Both the 5' and 3' ends are -OH groups. If phosphate groups are required, please specify this when ordering. In this case, a phosphorylation (PO4 modification) fee will be charged.
When analyzing synthetic Oligo DNA products using 3% Agarose gel electrophoresis, many bands are observed, Why?
Denaturing PAGE electrophoresis must be used for Oligo DNA. Oligo DNA is single-stranded and prone to forming complex secondary structures. Therefore, during Agarose gel electrophoresis, multiple bands often appear (and Agarose gel electrophoresis cannot be used for quantification).
