While the total molecular weight of aldolase is reported to be 160 kDa, this enzyme has not been tested for use as a molecular weight marker. Suitability would have to be determined by the end users.

What is the molecular weight (MW) of the product?
1 answer-
The molecular weight of aldolase from rabbit muscle is 161,000 daltons, and it is a tetramer composed of subunits of 40,000 daltons. This information is detailed in the research article: "The molecular weight of rabbit muscle aldolase and the properties of the subunits in acid solution" by Sia, C.L., and Horecker, B.L., published in the Arch. Biochem. Biophys. journal, volume 123, issue 1, pages 186-194 in 1968.
