It will save you a lot of time, effort, and probably money to have the peptide synthesized by a company that specializes in custom peptide synthesis. There are many such companies, so you can shop around for a good price.
Peptide synthesis is the process of making short sequences of polypeptides by adding one amino acid at a time. This process is useful for creating specific sequences that represent epitopes of certain protein domains that may or may not be modified by moieties, such as phosphate groups.
Peptides are synthesized by coupling the carboxyl group or C-terminus of one amino acid to the amino group or N-terminus of another. ... Chemical peptide synthesis starts at the C-terminal end of the peptide and ends at the N-terminus. This is the opposite of protein biosynthesis, which starts at the N-terminal end.
