Densitometric evaluation of the multimer pattern of recombinant vWF.

Recombinant WT vWF was compared with the product from the coexpression of WT and 2A/IIE vWF in the proportion of 1:39. Ultralarge multimers were absent (arrows), and there was a relative decrease in large multimers in the multimer pattern of the coexpressed vWF.
