Dopa Decarboxylase/DDC Antibody [Unconjugated]

Western blot shows lysates of mouse kidney tissue, PC-12 rat adrenal pheochromocytoma cell line, and human kidney tissue. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human/Mouse/Rat Dopa Decarboxylase/DDC Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3564) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). A specific band was detected for Dopa Decarboxylase/DDC at approximately 54 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Dopa Decarboxylase/DDC was detected in immersion fixed IMR-32 human neuroblastoma cell line using Goat Anti-Human/Mouse/Rat Dopa Decarboxylase/DDC Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3564) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; Catalog # NL001) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm.

Dopa Decarboxylase/DDC was detected in immersion fixed paraffin-embedded sections of human brain (substantia nigra) using Goat Anti-Human/Mouse/Rat Dopa Decarboxylase/DDC Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3564) at 1 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue). Specific staining was localized to neuronal cytoplasm.

Dopa Decarboxylase/DDC was detected in perfusion fixed frozen sections of mouse brain using Goat Anti-Human/Mouse/Rat Dopa Decarboxylase/DDC Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3564) at 5 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue). Specific staining was localized to neuronal cytoplasm.

DOPA decarboxylase is expressed non-uniformly in the CNS vasculature.(A–F) Coronal section of a P7 C57BL/6 brain stained for either GS lectin (green) to mark blood vessels or DOPA decarboxylase (DDC; magenta). Rightmost column shows merged images. Images are from the same brain section and correspond to cortex (A and B), striatum (C and D), and basal forebrain (E and F). DDC immunoreactivity is observed in blood vessels and in axon terminals, and in the latter it appears as distinct puncta in the cortex or more concentrated staining in the striatum. Yellow arrows in (C) indicate a large vein. Str, striatum; Ctx, cortex; AC, anterior commissure; Scale bar: 50 um.

Background

Dopa decarboxylase (DDC), also known as aromatic amino acid decarboxylase, is a group II decarboxylase (1). The enzyme catalyzes the decarboxylation of aromatic L-amino acids to produce the corresponding amines. DDC produces the neurotransmitters dopamine and serotonin from L-Dopa and L-5-hydroxytryptophan, respectively. The inhibition of DDC could be used for the treatment of schizophrenia and Parkinson's disease (2).
