Figure 2From: In vivo multiplex quantitative analysis of 3 forms of alpha melanocyte stimulating hormone in pituitary of prolyl endopeptidase deficient miceIn vitro time course of PREP activity on α-MSH 1–13 . The increase of α-MSH1–12 (pink line) fits a linear regression with R2 = 0.9370 (black line). The ratio of α-MSH1–13/α-MSH1–12 decreases in a corresponding fashion (blue line).Back to article page
