Experimental Data

Antibodies produced using PolyExpress™ have ELISA titers as high as polyclonal antibodies produced using a traditional protocol.

ELISA analysis of purified antibody generated by either PolyExpress™ protocol or traditional protocol.

ELISA analysis of purified antibody generated by PolyExpress™ Antibody Service.
PolyExpress™ generated an antibody with ELISA titer> 1: 256,000 which is higher than guaranteed.

Polyclonal Antibody Services Recommendations

For polyclonal antibodies targeting poorly defined epitopes we recommend protein antigens. Protein antigens provide the immune system the complete profile of exposed epitopes in the same conformational context the antibody will ultimately recognize the antigen such as FACS, sandwich ELISA, or receptor blocking for example. If financial constraints prevent selection of protein antigen packages, we recommend using the maximum amount of peptide antigens with our Gold package. Read More »

Capitalizing on our time-tested experience and proprietary technologies, GenScript offers guaranteed custom polyclonal antibody services with proven success rates.

	Our OptimumAntigen Design Tool combines the industry's most advanced algorithms with GenScript's professional expertise resulting in: Strong Antigenicity Avoidance of non-surface epitopes Specify desirable cross-reactivity Elimination of re-synthesis delays with a built-in peptide tutorial for synthesis and solubility Choose the best antigen conjugation and presentation options for your desired assay(s) A guaranteed immune response
	Our PolyExpress Gold package increases success rate by using more than one antigen peptide for each protein
	A proprietary immunization adjuvant elicits a stronger and faster cellular immune response with longer immune sustainability, making the production of high-titer, high affinity custom antibodies possible. *High Immunoaffinity   *Increase response   *Diminished toxicity
