SERVA Protein Assay Kits

Why different quantification methods?

Although there is a wide variety of protein assays available, none of the assays can be used without first considering their suitability for special applications. Each assay has its own advantages and limitations. Therefore, it is often necessary to obtain more than one type of protein assay for research applications.
