Anti-TH (phospho S19) Antibody - Identical to Abcam (ab194785)

This rabbit polyclonal antibody from Antibodies.com targets Tyrosine Hydroxylase (TH) only when phosphorylated at Serine 19, a modification linked to rapid enzyme activation in catecholaminergic neurons and adrenal chromaffin cells. Conjugated to nothing and supplied fully unconjugated, it slots straight into custom immunofluorescence workflows, including tyramide signal amplification protocols where a free primary is essential. Raised in Rabbit and purified as polyclonal IgG, the reagent is provided at 50 µl per vial and is validated for IF on Human and Rat tissue, making it a practical choice for mapping stress- or drug-induced changes in dopaminergic and noradrenergic pathways. The reagent carries the Abcam-compatible catalogue ab194785, which simplifies side-by-side benchmarking against existing lab stocks. Store refrigerated between shipments, protect from light, and avoid repeated freeze-thaw cycles to preserve phospho-specific binding activity.
