I precipitate serum albumin according to this article(A modified protein precipitation procedure for efficient removal of albumin from serum.)

. I wanted to assay albumin concentration by Bradford after which SDS PAGE GEL ELECTROPHORESIS was done. Therefore I resolubilized albumin precipitation with mixture of urea, tiourea, SDS (I do not have CHAPS therefore I use 10%SDS instead) and DDT, but the precipitates do not solubilize. Would you please guide me in this regard?
