• May 18, 2026 Nanodrop 230 260 other salts. The 230/260 ratio is the ratio of absorbance at 230 nm to absorbance at 260 nm. A pure nucleic acid sample will have a relatively high 260 nm absorbance and a low 230 nm absorbance, resulting in a favorable 230/260 ratio. A high 230/260 ratio indicates significant contamination, poten By Miss Sonia Bergstrom

Some Nanodrop software packages allow for inputting the specific protein sequence to obtain a more accurate concentration calculation. Purity assessment for proteins can also be done by comparing the A280/A260 ratio; high nucleic a By Vaughn Cruickshank
