Nucleic Acid Concentration from OD260 Calculator

Calculator to give the concentration of DNA, RNA, and oligonucleotides based on spectrophotometer readings at OD260.

This calculator uses the extinction coefficients for dsDNA (50), ssDNA (40), RNA (40) or the approximate extinction coefficient for single stranded oligonucleotides (33)  to calculate the nucleic acid concentration from the Optical Density (OD260) reading taken with a spectrophototometer.
