One of the most critical factors that determine the success or failure of an ELISA experiment is the incubation process. As a solid-phase immunoassay, ELISA involves antigen-antibody binding reactions on a solid surface. For the antigens or antibodies in the liquid phase to bind completely to their corresponding partners on the solid phase, the reaction must occur under controlled temperature and time conditions. Shanghai Jinma Biotechnology Co., Ltd. emphasizes that proper attention to the incubation step is essential when using ELISA kits.
The incubation time is inversely related to temperature—higher temperatures generally require shorter incubation times. The most common incubation temperatures used are 37°C and room temperature (20–25°C), followed by 43°C and 2–8°C. Some operators may alter the recommended incubation time or temperature based on personal preference, which can lead to inaccurate results. It's important to follow the manufacturer's instructions, as different ELISA kits may have specific requirements. Changing these parameters without justification can significantly affect the reliability of your data.
For incubation, ELISA instruments typically come with a dedicated heating block or water bath system. When using an incubator, place the ELISA plate inside a humidified chamber. A wet cloth should be placed at the bottom of the box to maintain moisture, and the plate should be positioned on top of it. Avoid stacking plates to ensure even temperature distribution across all wells. If conducting experiments at room temperature, make sure the ambient temperature stays within the specified range. Strict control over both time and temperature is crucial for consistent and reproducible results.
Shanghai Jinma Bioassay Kits use high-quality raw materials imported from reliable sources. They include a specially formulated diluent that ensures low intra- and inter-assay variability (less than 10%). These kits undergo rigorous cross-reactivity, interference, and stability testing to guarantee performance. With high sensitivity and accuracy, they deliver excellent results for various applications such as cytokine, chemokine, growth factor, and immunoglobulin detection. ELISA is widely used in research and diagnostic settings due to its ability to provide precise quantitative and qualitative data while maintaining cost-effectiveness.
By following best practices and using reliable reagents, researchers can maximize the performance of their ELISA experiments. Always refer to the kit's instructions and maintain strict control over experimental conditions to ensure accurate and meaningful outcomes.
