OPD as a Substrate in ELISA
The OPD (o-phenylenediamine dihydrochloride) substrate is commonly used in ELISA for colorimetric detection. In this kit, OPD reacts with the enzyme-linked secondary antibody to produce a yellow-orange product, which can be measured at 450 nm using a microplate reader.
Advantages of OPD:
- High sensitivity for low-abundance targets.
- Stable and reproducible colorimetric signal.
- Easy handling and compatibility with standard ELISA protocols.

Step-by-Step Procedure for the ELISA Kit
- Coating: The microplate is pre-coated with chick type II collagen.
- Sample Addition: Mouse serum or test samples are added to the wells, allowing antibodies to bind to the antigen.
- Secondary Antibody: A conjugated secondary antibody is added to detect the bound IgG1.
- Substrate Reaction: OPD substrate is added to produce a measurable colorimetric change.
- Detection: Results are read using a microplate reader at 450 nm.

Storage and Stability
The kit components should be stored at 2–8°C and are stable until the expiration date printed on the label. Avoid repeated freeze-thaw cycles to maintain reagent integrity. For storage and handling guidelines, consult the World Health Organization (WHO).
Advantages of Using the Kit
- Efficiency: Minimal hands-on time with quick turnaround for results.
- Accuracy: High specificity for IgG1 subclass ensures reliable data.
- Versatility: Suitable for various research applications, including arthritis and cartilage biology.
Frequently Asked Questions (FAQs)
- Can the kit be used for other species?
- No, this kit is designed specifically for detecting mouse antibodies against chick type II collagen.
- What is the dynamic range of detection?
- The kit typically provides a dynamic range of 1–100 ng/mL, but this may vary depending on experimental conditions.
- Is OPD the only substrate option?
- While OPD is the preferred substrate for its sensitivity, other substrates like TMB (3,3′,5,5′-Tetramethylbenzidine) can also be used depending on assay requirements.
