Question

Determinig concentration of protein from molecular weight

Answer 1

If the MW ( Molecular Weight ) of theprotein is 40 KD, then the molar concentration for this protein product is 200 (µg/mL)/ 40 (KD) = 5 µM. Frommolar concentration to massconcentration: The simple formula is: ( µg/mL ) = ( µM ) * ( MW in KD) , ( ng/mL ) = ( nM ) * ( MW in KD) , ( pg/mL ) = ( pM ) * ( MW in KD) .
