Figure 1: Expression of NGAL in the sera of normal donors and stroke patients. (A) A representative Western blot shows the expression NGAL in the sera of control (C), ischemic (I), and hemorrhagic (H) stroke patients. (B) The levels of NGAL in the sera of normal donors and stroke patients were measured by ELISA. Data were analyzed by a one-way ANOVA with Newman– Keuls post hoc tests. There was a significant induction of NGAL in hemorrhagic stroke patients (*P<0.05) compared with normal donors and ischemic stroke patients.
