Fig. 1. A2RE11, zipcode and AURE bind different groups of proteins. Coomassie-blue-stained SDS/polyacrylamide gel showing rat brain proteins that bound to magnetic particles bearing immobilized MBP mRNA trafficking sequence (A2RE11), ß-actin mRNA 5' zipcode (5'ZIP), the AU-rich response element (AURE) or a non-specific RNA sequence (NS1). This figure was created from an image of a single gel by deletion of every second track, which contained irrelevant samples. The positions of standard proteins are shown on the left, with molecular masses in kDa.
