The Y-P30 peptide is very stable and forms oligomers that migrate at a molecular weight between 10–15 kDa. (A) Oligomers are highly stable and resistant to SDS and reducing agents added for 2 h or overnight (ON). 10 μg synthetic peptide were loaded in each lane. (B) Storage of the peptide in solution for up to 14 days at room temperature in an Eppendorf tube on a lab bench does not lead to obvious degradation of the peptide multimer. 13,5 μg of the peptide were loaded in each lane.
