Figure 2

A, Gel of Sprague-Dawley urines from increasing age (right to left) showing, in the 14-20 kDa region, transition from an initial pair of bands to a group of four in which two attributed to α2u-globulin become dominant (see also Figure 3). A band attributed to an albumin, by analogy with that in Figure 4B indicated (arrow), in the 45-66 kDa region apparently increased with age. B, Gel of Wistar urines from increasing age (right to left) showing a pattern analogous to that in Sprague-Dawley rats (Figure 4A). A band indicated by the arrow was identified from tryptic digest data as an albumin.
