427kilodalton
427 kilodalton (kDa) is a unit of molecular mass used in biochemistry and molecular biology to describe the size of proteins and other macromolecules. A dalton (Da) is defined as one twelfth of the mass of a carbon-12 atom, and one kilodalton equals 1,000 Da. Thus, 427 kDa corresponds to 427,000 daltons.
In terms of protein size, a 427 kDa molecule could be a large single polypeptide or a
Mass determination methods include mass spectrometry (electrospray or MALDI), analytical ultracentrifugation, and light scattering coupled with
In practice, the figure 427 kDa is used to express the approximate size of sizeable proteins, enzymes,
