Confirmed reactivity:PEB has been tested on a wide range of species and tissues from Higher plants, Mosses, Llichens, Algae, Diatoms, Dinoflagellates, Cyanobacteria. Extracts may be quantified using detergent (LDS) compatible methods, and have been shown to give highly reproducible and quantitative results in subsequent SDS PAGE gel electrophoresis, Western blotting, and Immunoprecipitation (IP). Most of Agrisera commercial antibodies are tested on plant or algal samples extracted with this buffer. An example can be found here.
