make an Antibody against a Peptides
If your peptide is synthesized with a terminal cysteine residue (i.e., a free sulfhydryl group, -SH), you can use any maleimide-activated carrier protein to create an immunogen. One-step chemical reactions are easy with Pierce Sulfo-SMCC Pre-Activated Carrier Proteins (Figure 1). If your hapten does not have a sulfhydryl group, you can use EDC chemistry (Figure 2) to couple amines (lysine) or carboxylic acids (glutamic, aspartic acid or 5′-phosphate) to the carrier protein.
