As mentioned on the product page, it is suitable for ELISA, so can it be used for detecting IL-6 levels in rat serum samples using ELISA? If yes, what percentage will be ideal for the assay, and how will the working concentration be prepared?
1 answer-
The suitability of this product for ELISA has not been tested in-house and is likely based on literature or customer feedback. Therefore, specific recommendations for its use in detecting IL-6 levels in rat serum samples using ELISA cannot be provided. It is advised to consult the literature or conduct empirical testing to determine the appropriate usage in this application.
