Optimizing Your ELISA: The Role of ABTS Sensitivity and Signal
In the intricate world of ELISA (Enzyme-Linked Immunosorbent Assay), achieving a strong and reliable signal is paramount for accurate detection and quantification. ABTS (2,2'-Azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt) plays a pivotal role in this process as a highly sensitive chromogenic substrate for peroxidase enzymes. Its unique properties allow researchers to achieve excellent detection limits in their immunoassays.
The sensitivity of ABTS stems from its ability to efficiently form a colored product in the presence of a peroxidase enzyme and its substrate, hydrogen peroxide. The resulting soluble green cation has a high molar extinction coefficient, meaning even small amounts of enzyme activity can generate a measurable optical signal. This makes ABTS a preferred choice when detecting low concentrations of analytes or when working with samples that might have high background noise.
Researchers often look to buy ABTS to leverage its signal-generating capabilities. The green color produced by ABTS is easily quantifiable using a spectrophotometer at 405 nm, providing a clear and stable signal that can be monitored over time for kinetic studies or at a fixed endpoint for standard ELISA protocols.
When sourcing ABTS, it is essential to partner with a reputable supplier. NINGBO INNO PHARMCHEM CO.,LTD. is a trusted source for high-purity ABTS, ensuring consistent performance in your ELISA experiments. Understanding the price of ABTS from reliable manufacturers like NINGBO INNO PHARMCHEM CO.,LTD. will help in planning your experimental costs effectively. Purchasing ABTS from a reliable supplier guarantees that you are using a substrate that meets stringent quality standards.
To optimize the use of ABTS in your ELISA, consider factors such as substrate concentration, pH of the buffer system, and reaction incubation time. Proper handling and storage, typically at 4°C and protected from light, will maintain the substrate's activity. By understanding the nuances of ABTS and sourcing it from quality providers like NINGBO INNO PHARMCHEM CO.,LTD., researchers can significantly enhance the sensitivity and reliability of their ELISA assays.
