Choose Your Performance Tier for Optimal Results
We offer two optimized formats to suit your specific research requirements. Purchase any tier and gain access to our complimentary expert testing service.
| Feature | Tier 1: Standard 5AR ELISA Kit | Tier 2: High-Sensitivity 5AR ELISA Kit |
|---|---|---|
| Core Technology | Optimized one-step sandwich ELISA with proprietary dilution buffer. | Biotinylated recombinant mAb (>95% pure) + Streptavidin-HRP (≥500 U/mg). |
| Key Advantage | Cost-Effective & Robust. Utilizes a simultaneous antigen-antibody incubation and a specialized diluent engineered to reduce interference from hemoglobin and lipids, ensuring stable, low-background performance. | Ultimate Precision & Sensitivity. The biotin-streptavidin signal amplification system directly overcomes matrix effects, delivering superior signal-to-noise for the most challenging samples or low-abundance targets. |
| Ideal For | Routine quantification in standard research models where sample material is not limiting. | Applications demanding the highest sensitivity, such as low-volume or low-expression samples. |

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.
