Immunohistochemical Staining of Tyrosine Hydroxylase in Paraffin Embedded Rat Brain
Immunohistochemical analysis of a formalin fixed and paraffin embedded rat brain tissue section using Tyrosine Hydroxylase antibody at 1:5000 dilution.

Western Blot: Tyrosine Hydroxylase Antibody [NB300-109] - Specific knockdown of Hif1 alpha diminished phosphorylation of tyrosine hydroxylase & thereby reduced cellular dopamine content in PC12 cells. (A) Extrinsic hypoxia led to a time-dependent upregulation of Hif1 alpha & Hif2 alpha in PC12. (B) RNA interference using siRNA against Hif1 alpha repressed the expression of Hif1 alpha also under extrinsic hypoxia while Hif2 alpha remains unaffected. (C) Extrinsic hypoxia increased cellular dopamine content in PC12 control cells (transfection without siRNA). This effect was diminished by knockdown of Hif1 alpha. (D) Furthermore, phosphorylation of TH was decreased by knockdown of Hif1 alpha. Three independent experiments (n = 3–6). Mean ± SEM.
