65kDa
65kDa denotes a molecular mass of approximately 65,000 daltons and is commonly used to describe the size of proteins or protein complexes. The label is a practical convention in biochemistry and molecular biology, helping researchers communicate about the approximate heft of a polypeptide rather than its exact mass.
Molecular weight in this range is typically estimated from electrophoretic mobility in SDS-PAGE or gel filtration
The 65 kDa figure also relates to the typical number of amino acids in a protein. With
In naming and literature, “65 kDa” often appears as a descriptor in place of a precise mass,
