Hi, You can make it :) There are a number of good ways to do so, but my favorite one is to order Cys-Arg dipeptide and then use iodoacetamide-agarose resin (very cheap) to load up the peptide. This method allows you to quantify the loading, if you care to know how much you immobilized and also it's extremely robust and specific.
