Multilayer an integral element, for the detection of albumin.

摘要

PURPOSE:To decrease the errors by disturbance of globulin and other proteins by incorporating the compsn. consisting of an indicator which discolors by bonding to the albumin dispersed in a hydrophilic polymer or mixture composed of said polymer and hydrophobic polymer and pH buffers in a porous expansion layer. CONSTITUTION:An aq. soln. consisting of 58g ternary copolymer of acrylaminde- N-vinyl-2-pyrrolidone-methallyl alcohol, 70mg p-nonylphenoxy polyglycidol and 2g aq. 30% formaldehyde soln. is coated on a colorless transparent polyethylene terephthalate PET film having 180mum thickness and is crosslinked and cured by drying for 48hr at 70 deg.C to form a water absorptive layer. Water is supplied to the surface of the water absorptive layer to wet the layer; thereafter, the layer is cleaned and a knit fabric consisting of spun PET yarn imparted with a hydrophilic property is press-laminated on such water absorptive layer, by which the porous expansion layer is obtd.
