The Human 5-Alpha Reductase (5AR) ELISA Kit enables quantitative measurement of 5α‑reductase protein levels, providing essential insights into androgen metabolism and related pathologies. In humans, three isoenzymes exist (SRD5A1, SRD5A2, and SRD5A3), with SRD5A1 and SRD5A2 primarily responsible for the NADPH‑dependent reduction of testosterone to the more potent androgen, dihydrotestosterone (DHT). Because DHT is a critical activator of the androgen receptor, this human 5‑alpha reductase ELISA kit is widely applied in prostate disease research to investigate the pathogenesis of benign prostatic hyperplasia (BPH) and prostate cancer, and to evaluate the pharmacodynamics of 5AR inhibitors such as finasteride and dutasteride in androgen‑dependent conditions. The kit is equally valuable in androgenetic alopecia and dermatological research for studying the mechanisms behind hair follicle miniaturization and excessive sebum production in acne, as well as for assessing the efficacy of hair‑loss treatments and cosmetic interventions. Furthermore, it supports endocrinology and developmental biology studies by enabling the analysis of steroid hormone biosynthesis and metabolic pathways, including the investigation of inherited disorders of sexual development caused by loss‑of‑function mutations in SRD5A2. With its straightforward protocol and high sensitivity, this human 5AR ELISA kit is a robust research tool for laboratories focused on androgen biology, endocrinology, and dermatology.

Technical Specifications & Assay Principle
Principle: This kit employs a validated one-step sandwich ELISA. 5α-Reductase present in the sample is captured between an immobilized antibody and an enzyme-conjugated detection antibody. Subsequent reaction with TMB substrate produces a color change measurable at 450 nm, proportional to the enzyme concentration.
Performance Specifications:
- Sensitivity: < 1.0 ng/mL.
- Detection Range: 1.0 – 200 ng/mL.
- Accuracy (Linearity): Correlation Coefficient R ≥ 0.9900.
- Precision: Intra- & Inter-assay CV < 15%.
- Specificity: Minimal cross-reactivity.
- Storage: 2-8°C; 6-month shelf life.
Sample Preparation: For cell and tissue samples, use appropriate lysis buffers. Clarify all samples by centrifugation (3000×g for 10 mins) and store at -20°C in aliquots. Serum may require specific dilution per protocol.
Streamlined Assay Workflow
- Addition: Add 50 µL of standards or prepared samples to the pre-coated wells.
- Detection & Incubation: Add 100 µL of the HRP-conjugated Detection Antibody. Incubate at 37°C for 60 minutes.
- Wash: Aspirate and wash the plate 5 times thoroughly.
- Development: Add 50 µL each of Substrate A and B. Incubate at 37°C for 15 minutes in the dark.
- Measurement: Add 50 µL Stop Solution. Measure absorbance at 450 nm within 15 minutes.
