Custom Antibodies

Your Idea, Our Laboratory

Let GeneTex become your personal custom antibody production facility. We have produced over 35,000 polyclonal antibodies. Use our experience and expertise to help advance your research.


Featured characteristics

1.   Proprietary bioinformatics database identifies the ideal target epitope and optimizes synthesis, solubility and antigenicity
2.   Efficient production of high quality antigens using prokaryotic expression or peptide conjugation
3.   Enhanced cocktail immunization technique produces high-titer antiserum
4.   Highly specific antigen affinity purification


Flow Chart


Target Protein Analysis:
