Assay Principle:>

The DetectX hours. Please read the complete kit insert for more information before performing this assay. Use our provided allopregnanolone standard to generate a standard curve for the assay.

Protocol Summary:

• Add standards or diluted samples to the provided transparent microtiter plate coated with goat anti-mouse IgG antibody.
• Introduce the allopregnanolone peroxidase conjugate and allopregnanolone mouse monoclonal antibody to initiate the immunological reaction.
• Incubate the plate covered, shaking at room temperature for 2 hours. The reaction varies inversely with the allopregnanolone concentration in the sample.
• After incubation, remove excess conjugate and add the TMB substrate. The substrate reacts with the bound conjugate to produce a detectable signal.
• Measure the signal intensity at 450nm with a plate reader and calculate allopregnanolone concentration using the standard curve.

Background:

Allopregnanolone, also known as 3α-hydroxy-5α-pregnan-20-one, THP, or THPROG, is a significant neurosteroid in blood and brain tissues. It is a metabolite of progesterone and a powerful modulator of GABAA receptors, exhibiting notable anxiolytic and anticonvulsant properties. Allopregnanolone biosynthesis involves converting progesterone into 5α-dihydro progesterone by 5α-reductase type I, followed by conversion into allopregnanolone by 3α-hydroxysteroid oxidoreductase isoenzymes.

Allopregnanolone’s impact extends to neurological health, with links to conditions like anxiety and depression, particularly when its synthesis is inhibited by drugs such as finasteride and dutasteride. Its role in neurogenesis is also significant, with studies showing potential in reversing neuron deficits and cognitive impairments in Alzheimer;s importance in both physiological and pathological contexts, particularly in neurology and mental health.
