Preparation Of Peptide-KLH Conjugates For Immunization

.(6) For the -SH coupling, warm the other aliquot of KLH to room temp. Add 1/9 th volume of Iodoacetic acid N-hydroxysuccinimide ester at 100mg/ml in DMSO. Make the DMSO stock fresh, and protect the iodoacetamide reagent from light. We make our own IAA-NHS ester

that are not clear, using DMSO instead of glycerol for the first polymerization step appears to increase the labeling stoichiometry by ~25% for C2CF-SNHS ester. For labeling with rhodamine (tetramethylrhodamine NHS ester) and X-rhodamine, we generally use glycerol
