Adsorption effects of the doping relevant peptides Insulin Lispro, Synachten, TB-500 and GHRP 5

Adsorption effects of the doping relevant peptides Insulin Lispro, Synachten, TB-500 and GHRP 5
The tendency of peptides to adsorb to surfaces can raise a concern in variety of analytical fields where the qualitative/quantitative measurement of low concentration analytes (ng/mL-pg/mL) is required. To demonstrate the importance of using the optimal glassware/plasticware, four doping relevant model peptides (GHRP 5, TB-500, Insulin Lispro, Synachten) were chosen and their recovery from various surfaces were evaluated. Our experiments showed that choosing expensive consumables with low-bind characteristics is not beneficial in all cases. A careful selection of the consumables based on the evaluation of the physico/chemical features of the peptide is recommended.
