Background Information

TH(Tyrosine 3-monooxygenase) converts L-tyrosine to L-3,4-dihydroxyphenylalanine (L-DOPA), the essential and rate-limiting step to formation of dopamine and other catecholamines. TH plays an important role in the physiology of adrenergic neurons and can be used as a marker for dopaminergic and noradrenergic neurons. This protein has 6 isoforms produced by alternative splicing with the MW from 44 kDa to 58 kDa.

This antibody is good for western blot. The dilution at 1/1000 was too strong but at 1/2000 it works perfectly.

  • Applications: Western Blot
  • Primary Antibody Dilution: 1/2000
  • Cell Tissue Type: Rat brain
