qPCR Copy Number
Convert a double-stranded DNA mass in nanograms to molecule count using length and the mean base pair mass of 650 daltons.
Description
Convert a double-stranded DNA mass in nanograms to molecule count using length and the mean base pair mass of 650 daltons.
qPCR Copy Number is a focused biology tool that convert a double-stranded DNA mass in nanograms to molecule count using length and the mean base pair mass of 650 daltons. It calculates locally from the values you enter and exposes the result without changing the source observations.1
When to use qPCR Copy Number
Use qPCR Copy Number when you need to convert a double-stranded DNA mass in nanograms to molecule count using length and the mean base pair mass of 650 daltons. Enter DNA mass and Template length using the definitions and units below so the result can be reproduced.
- DNA mass
- A finite measured or assumed value, expressed in ng.
- Template length
- An integer count or setting, expressed in bp.
How qPCR Copy Number calculates the result
The published tool contract uses this rule: Convert a double-stranded DNA mass in nanograms to molecule count using length and the mean base pair mass of 650 daltons.1
- Molecule count
- The calculated molecule count.
Limitations of qPCR Copy Number
The calculation does not propagate measurement uncertainty, sampling error, or biological and chemical variability.
Alternative or Complementary measurements
Retain the original DNA mass and Template length values and their units alongside the result. DNA Copy Number is useful when you instead need to calculate the number of DNA molecules from mass in nanograms and length in base pairs. Plasmid Copies Per Cell provides another view by helping you estimate plasmid copies per cell from plasmid and genomic DNA masses, correcting the mass ratio for their different molecule lengths.
