    Does anyone know if I can reverse denaturation by urea (7M)?

    I am working with lactoferrin and over my protocol for expression in vitro I have been used urea (7M) buffer for denaturation, however, I would like to proceed an assay with my lactoferrin and it should be intact. Can I reverse denaturation by urea of my lactoferrin? I appreciate any idea.
