thanks. no DMSO is used in our system. All in PBS or water buffer. the solubility of the peptide is very good. Also, the Biotin-conjugated IgG has the same phenotype, but we can see an obvious bell shaped curve, for the peptide it is a exponential growth curve, making the interpretion intriguing...
I guess: 1. Parital Biotinylation. Non-Biotinylated peptides is coated preferentially . 2. Reduced exposure of epitopes when coated at high concentration.
Thanks. I agree your 2nd guess makes every senes, but the question is possible? And The biotin-conjugation shall be good. So, 1st point shall be not possible. BTW, do you think it is some observation signficant and interesting?

Just a guess, Is it possible: These peptides are dimers or oligomers at high concentration, which can't bind the targeted protein. At low concentration, the oligomers dissociate to monomer, which can bind.
