I am performing an IP in which I am using a Protein G-bound IgG1 antibody to bind to my antigen of interest, a glycoprotein enriched in cell culture supernatant. Once I have performed the antigen binding to the Protein G-bound antibody, I want to try its elution with potassium thiocyanate 3.5 M. However, I do not have enough sample and my elution volume will be only about 50 ul. How can I get rid of the Potassium thiocyanate from this elution volume before running them on SDS PAGE?
