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).

Biology
Primer Melting Temperature Calculator
Estimate the melting temperature (Tm) of a PCR primer from its GC content and length using the simplified Wallace-rule approximation. Useful for quickly designing and checking primers before running PCR.
