Comparison of Mpl expression in platelets from normal adult controls, newborns, and TAR syndrome patients.

Western blots were scanned, and the intensity of each lane was measured by pixel quantitation using the MacBas v2.2 software. Mpl levels were normalized to GPIIb expression and compared. Results are expressed in arbitrary units resulting from the ratio of the Mpl to GPIIb band. Four patients with a TAR syndrome, 4 adult controls, and 4 newborns were studied.
