Maths in Biology
Biomaths an Android application which contains the functions in thse pages can be found
here
on the Android Market Place / Google Play.
Purpose of these pages
These pages allow you to perform simple calculations that are common enough for
me to write this, but rare enough for everyone to forget how to do it.
Making solutions
This page helps you calculate how much to add to make a solution of the right molarity
Mass calculation
This page helps you calculate how much of a solution you can make given an amount of the compound and the desired molarity
Volume calculation
This page helps you calculate the maximum concentration of a solution you can make for a given mass and volume
Molarity calculation
This page helps you calculate how much of a stock solution you need to use to make a working solution of a certain concentration
Stock solution calculation
DNA concentrations
This page converts ODs in to nucleic acid concentrations for long sequences
OD > concentration
This page converts ODs of small single stranded primers to concentrations
OD > primer concentration
This page calculates the amount of protein in a nucleic acid solution
Protein in a nucleic acid solution
Centrifugation calculations
This page converts RPM to G force and G force to RPM for a given rotor radius
Centrifugation calculations
Radioactivity
This page calculates the current activity of a radioactive compound given is inital activity, time since the activity date and the isotopes half life.
Radio isotope decay
This page calculates the molarity of a solution given is specific activity per ml and its activity per millimole.
Radioactivity to molarity
