Troubleshooting ELISA can often feel like navigating a maze of perplexing issues. A slight deviation in protocol or reagent handling can dramatically impact the validity and reliability of your results. This section will delve into common pitfalls encountered during ELISA experiments, providing actionable solutions to help you achieve accurate and reproducible data.
One frequently occurring problem is non-specific binding, that can lead to false positive signals. To mitigate this, ensure that all reagents are completely diluted in appropriate buffers, and optimize blocking steps by using a high quality blocking agent such as bovine serum albumin (BSA) or casein.
Another common issue is poor signal-to-noise ratio, causing to weak or undetectable signals. This can be addressed by optimizing the amount of primary and secondary antibodies, and ensuring sufficient incubation times for each step.
Furthermore, temperature fluctuations during the assay process can significantly impact antibody binding and enzyme activity. Maintain a consistent temperature throughout the experiment, ideally at room temperature or as specified by the manufacturer's instructions.
