The 1-Step™ ABTS Substrate Solution is a water-soluble HRP (Horseradish Peroxidase) substrate used in ELISA assays to produce a green end product. This substrate is ideal for applications where lower sensitivity is acceptable or to avoid high background signal caused by more sensitive substrates like OPD or TMB.
Key Features:
- Water-Soluble Substrate:
- Produces a green-colored end product upon reaction with HRP.
- Absorbance peaks at 410 nm and 650 nm.
- Controlled Sensitivity:
- Less sensitive than TMB or OPD, reducing background noise in ELISA assays.
- Slower color development (approximately 20 minutes) provides more control.
- Ease of Use:
- Ready-to-use, no additional preparation required.
- Available in solution or as ABTS Substrate Tablets for added convenience.
- Non-Toxic Alternative:
- Provides a safer option for laboratory workflows compared to other substrates.
