WebFor those of you not familiar with the term "Daltons", this is just another way of referring to molecular weight. Most of the protein had a molecular weight of 10,000 (i.e., 10,000 grams per mole) so it would not pass through these membranes. In contrast, the salt (sodium chloride) had a molecular weight of 58.5 Daltons (if not dissociated).
