Custom Peptide Services


Custom Peptide Overview


Rockland Immunochemicals custom peptide synthesis service provides synthetic peptides that include a broad range of labels, modifications, scales, purities and delivery time options.  Synthetic peptides are commonly used as the epitope presented to the immune system.   Presentation of the peptide epitope generates a very specific antibody response that targets the unique peptide sequence.   This is very useful when generating highly specific antibodies.  Peptides immunogens can be used for generation of both monoclonal and polyclonal antibodies, are excellent as control reagents for certain immunoassays and for targeting post-transitional modifications.

Peptide synthesis is easy with Rockland.  Clients can design their own peptide, or clients can utilize our peptide consulting service available with antibody generation projects.  Peptide synthesis may include any of the following peptide modifications:



Available Peptide Modifications



Amidation       PEGylation
Acetylation (Ac)   Special Amino Acid
Phosphorylation       Formylation (For)
Biotin   BSA, KLH, OVA Conjugation
Disulfide Bridge   Enatiomers
Tags   Dyes (FITC etc.)
Mono-, di- or trimethylated lysine   Spacers
13C/15N Isotopes    



Custom conjugation of peptides to a carrier protein (i.e. KLH or Ovalbumin) for antibody generation is available using Rockland's custom conjugation service.



Epitope Mapping

Rockland offers nested or overlapping peptide generation as a custom service.  Ask about out epitope mapping service.



The Rockland Custom Peptide Synthesis Advantage

Rockland manufactures and validates peptides for academic and biopharma clients.  The peptides are analyzed for their physical characteristics including the peptide solubility and uniqueness.  Peptides can be ordered in several levels of purity from 80% to over 95% pure.  Rigorous quality control testing including mass spectroscopy sequence validation and TFA removal ensures that the final polypeptide product meets or exceeds Rockland’s standards for robust performance in antibody development or if used in immunoassays.  Rockland has demonstrated success in generation of peptides and antibodies for high specificity, detection of post translational modifications such as phosphorylation and epigenetic markers like acetylation and methylation.
