Why Our Technology Stands Out
To ensure the highest data integrity, this kit employs an advanced detection system:
- High-Purity Biotinylated Antibody: Utilizes a recombinant monoclonal antibody with >95% purity, ensuring exceptional specificity and batch-to-batch consistency.
- Powerful Signal Amplification: Incorporates a high-activity Streptavidin-HRP complex (≥500 U/mg). This robust biotin-streptavidin interaction provides significant signal amplification.
- Minimized Matrix Interference: This combined system is engineered to directly circumvent sample matrix effects and background interference, resulting in cleaner signals, superior sensitivity (<1.0 nmol/L), and more accurate quantification in complex biological fluids.

Expert-Recommended Workflow
Sample Preparation:
Collect serum or plasma using standard procedures. For all samples, a 1:5 pre-dilution is required: mix 10 µL of sample with 40 µL of the provided Sample Diluent. Aliquot and store samples at -20°C to avoid freeze-thaw degradation.
Assay Procedure Summary:
- Add: Pipette 50 µL of standards or diluted samples into wells.
- Incubate: Add 100 µL of the prepared detection complex (Biotin-Ab + SA-HRP). Incubate at 37°C for 60 min.
- Wash: Perform 5 wash cycles using the prepared 1X Wash Buffer.
- Develop: Add 50 µL each of Substrate A and B. Incubate at 37°C for 15 min in the dark.
- Stop & Read: Add 50 µL Stop Solution. Measure absorbance at 450 nm within 15 minutes.
Calculation: Plot the standard curve and interpolate sample values. Multiply the result by the dilution factor (5) for final concentration.

Frequently Asked Questions (FAQ):
Q: Why is the biotin-streptavidin system superior for 2,3-DPG detection?
A: This system provides powerful signal amplification, drastically improving the signal-to-noise ratio. It is particularly effective at mitigating non-specific background common in complex matrices like hemolysates, leading to more precise and reliable low-concentration measurements.
Q: What is your lead time for bulk orders?
A: As the direct manufacturer, we maintain efficient inventory and production. Typical lead times are 5-10 business days, with expedited options available.
Q: Do you provide technical documentation for grants or publications?
A: Yes. We supply comprehensive validation data, performance certificates, and detailed protocols suitable for grant applications and methodological sections in publications.
Q: Can this kit be used for diagnostic purposes?
A: No. This product is sold for Research Use Only (RUO). It is not intended for use in clinical diagnostic procedures.
