How many times has this happened to you? You're in a rush to get an experiment started. You make a mistake in calculating the molecular weight of your DNA/RNA or protein. It takes at least a day (if you're like me, sometimes more!) to figure out why the experiment didn't work.

Don't let this happen to you! With this app, you can quickly and accurately figure out the molecular weight of your macromolecule (DNA, RNA, or protein) from its length. For example, a 23nt single-stranded oligo is 0.008 ug/pmol (molecular weight = 7590 g/mol).

Alternatively, if you know the molecular weight, this app will give you the length of your macromolecule. For example, you can quickly discover that a 50kD protein is 455 amino acids.

If you make a calculation based on the wrong type of macromolecule, simply press the selector button until the correct type is displayed. The app remembers whether you last entered a length or weight and automatically recalculates the other fields.

Make your lab calculations on the fly, at your bench or your desk!
