Protein molecular weight calculator kDa

The rule of thumb for conversion of microgram amounts into picomole amounts at different protein molecular weights and peptide molecular weights is:

1000/Mw of protein in kDa = pmol/ug

You can use the table below for a quick conversion of your protein, depending on its size:
