Figure 2. MUP and total urinary protein output.

(a) Total urinary protein output corrected for urine dilution, (b) creatinine as a measure of urine dilution, and (c) uncorrected urinary protein concentration for male and female adults of musculus and domesticus from contact (C) or allopatric (A) origin. (d) A representative set of samples resolved by reducing SDS-PAGE, with standard molecular weight markers indicated on the left of the gel. Sample sizes: domesticus male contact (n = 22), male allopatric (n = 13), female contact (n = 26), female allopatric (n = 8); musculus male contact (n = 18), male allopatric (n = 13), female contact (n = 31), female allopatric (n = 12).
