ELISA Buffer
A number of buffers and solutions may be used for ELISA application. BioWORLD carries over 50 options of washing buffers to fit each specific sample’s individual requirements. Some are sold as ready-to-use solutions, while others are provided as 10X or 20X concentrations to be diluted and sterilized as desired. BSA solutions are ideal for blocking excess binding sites during the ELISA process.
