cross-reactivity of the ubiquitin antisera for tau protein , neurofilament proteins , and high molecular weight microtubule-associated proteins ( maps ) were ruled out by ( i ) the inability of the ubiquitin antisera to stain these proteins in immunoblotting experiments and ( ii ) the inability of tau , neurofilament , and map preparations , when preincubated with the ubiquitin antisera , to inhibit the selective neurofibrillar staining observed .
