- Cell Population Doubling Time & Continuous Growth Rate
Calculate exponential doubling time and continuous growth rate from a rising cell count or concentration measured over a positive time interval.
- Cell Suspension Dilution: Concentration & Volume
Balance cell concentration and volume before and after dilution using conservation of cell count and compatible volume units.
- DNA Insert Mass from Vector Mass & Molar Ratio
Calculate insert DNA mass from vector mass, fragment lengths and a chosen insert-to-vector molar ratio, with bp/kb and mass unit choices.
- Exponential Bacterial Growth & Doubling Time
Relate initial and final populations, elapsed time, hourly fractional growth and doubling time during ideal exponential growth.
- Log Reduction, Surviving Count & Percent Reduction
Convert positive before-and-after counts into decimal-log and percentage reductions, including inverse count calculations.
- Observed Mutant Fraction of a Population
Calculate observed mutant frequency from mutant and total counts, or recover a count from the fraction.
- qPCR Standard-Curve Efficiency & Amplification Factor
Convert a negative standard-curve slope to amplification factor and apparent qPCR efficiency, or recover slope from the factor.
