WebCalculate the RNA concentration using Beer's law. Beer's law states that A = εcl, where A is the absorbance, ε is the molar absorptivity (which varies depending on the molecule), c is the concentration, and l is the path length of the cuvette (usually 1 cm). For RNA, ε = 40 µg/mL·cm. Rearranging the equation, we get c = A/εl. http://biotools.nubic.northwestern.edu/OligoCalc.html
NEBioCalculator
WebDNA calculations to convert µg to pmol for double-stranded and single-stranded DNA, convert micrograms of DNA to pmol ends, calculate vector:insert molar ratio and convert OD260 readings to µg/ml. Also calculate molarity of solutions, perform molar conversions, calculate dilutions and perform other calculations common in molecular biology labs. WebFormula. concentration (ug/ml) = OD 260 x conversion factor. conversion factors: 1 OD 260 Unit = 50 μg/ml for dsDNA. 1 OD 260 Unit = 40 μg/ml ssRNA. 1 OD 260 Unit = 33 μg/ml ssDNA. ss oligo concentration (ug/ml) = OD 260 x MW x 1000 / ε 260. where MW = molecular weight of oligo (non-phosphorylated) and ε 260 = extinction coefficient of ... buechler law office
