Abstract

A non-immunological method for the detection of PhoA fusion proteins on Western blots has been developed. Bands representing the alkaline phosphatase-active species of the fusion proteins are visualized after incubation with the colorimetric alkaline phosphatase substrates nitroblue tetrazolium and 5-bromo-4-chloro-3-indolyl phosphate. Blocking the filters in 3% gelatin in Tris buffered saline containing 0.05% Tween-20 prior to color development is essential, and reactions are enhanced by extending blocking and development times. Fusion proteins can be detected over a broad protein concentration range. This method is based upon the ability of the fusion proteins to renature and regain enzymatic activity after immobilization on nitrocellulose.
