Tools: OD260 Units of Nucleic Acid to Concentration

OD260 units =
Nucleic acid:	DNA RNA ssDNA Single-Stranded Oligo
Concentration =	µg/ml of nucleic acid

Formula: OD260  x  conversion factor  =  µg/ml of nucleic acid

1 OD260 Unit  =  50µg/ml for dsDNA 1 OD260 Unit  =  40µg/ml ssRNA 1 OD260 Unit  =  35µg/ml ssDNA 1 OD260 Unit  =  20µg/ml for single-stranded oligo
