proBDNF Positive Control for Western Blot (#PCP-B257), is a recombinant, highly purified proBDNF protein in a ready-to-use single reagent format. This makes it a good positive control by loading it alongside the experimental lysates or samples in a SDS-PAGE. This product enables to check whether the primary and secondary antibodies are working as expected and also visualize a reference of the expected molecular weight of the target protein.
