Correlation of KRT19 expression and human RNA content in PDX cohort. The correlation between KRT19 expression relative to human references ACTB (in a) or OAZ1 (in b) and the human reference content relative to murine Actb was graphed. Each PDX blood sample gene expression levels were graphed as a scatterplot. Human reference gene Ct values were normalized on the murine Actb gene. Human KRT19 Ct values were normalized on human reference gene. The linear regression fit lines and Spearman’s rho correlation coefficients are reported
