Biology
DNA Concentration Calculator
Estimate double-stranded DNA concentration from absorbance at 260 nm using the standard 50 μg/ml per A260 conversion. The default UV-spectroscopy method used in every molecular-biology lab for quick nucleic-acid quantification.

Biology
PCR Efficiency Calculator
Compute the amplification efficiency of a qPCR reaction from the slope of a standard curve fitting Cq values against the log of template concentration. A slope of −3.32 yields 100% efficiency (true doubling per cycle).
