Figure 4: Peptain-1 is the preferred chaperone peptide for the antibody binding.
Peptain-1 and the chaperone peptides of other small heat shock proteins were tested by a competitive ELISA (A) and Western blotting (B, left panel) as described in Methods. The gel run in parallel was stained with Coomassie blue (B, right panel). M=molecular weight markers, 1= peptain-1, 2=αA-crystallin, 3=Hsp20, and 4=Hsp27.
