Background

Human aromatic L-amino acid decarboxylase (hDDC) is an enzyme that plays a crucial role in neurotransmitter biosynthesis by catalyzing the decarboxylation of L-3,4-dihydroxyphenylalanine (DOPA) to dopamine and L-5-hydroxytryptophan to serotonin. This enzymatic activity is a pivotal step in the synthesis of two key neurotransmitters, dopamine and serotonin, both of which are essential for the central nervous system's regulation of mood, behavior, and motor functions. The conversion of DOPA to dopamine by hDDC is particularly significant in the dopaminergic pathways, influencing motor control and emotional processes. The parallel conversion of L-5-hydroxytryptophan to serotonin underscores hDDC's role in serotoninergic pathways, crucial for mood and emotional regulation. It has to emphasize hDDC's specific contributions to neurotransmitter synthesis, highlighting its importance in maintaining the delicate balance of signaling molecules critical for neurological functions.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

  • Reconstitution Calculator

  • Dilution Calculator

  • Specific Activity Calculator

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
× = ×
C1   V1   C2   V2

The specific activity calculator equation

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
