While our Ab and Hsp27—Ab mixtures data not shown. This result suggests that the large Ab—Hsp20 intermediate formed is non-toxic. In addition, the data indicate that Ab did not form a toxic oli- gomer prior to formation of the Ab—Hsp20 complex. Summary Taken together, a number of conclusions can be drawn from our results. First, Congo red binding does not corre- late well with toxicity Fig. Representative electron micrograph of Ab with Hsp The sample While many small heat shock proteins alter Ab aggrega- containing lM Ab and 0.
