Alpaca Polyclonal Antibody Production Service

KMD Bioscience has a mature antibody production platform with advanced and improved antibody engineering technology. You can enjoy comprehensive polyclonal antibody production services, including peptide or protein antigen synthesis, animal immunization, antibody purification and QC control test. Polyclonal antibodies can also be raised against a customer supplied antigen. Our scientific team has been practicing in polyclonal antibody development for years, with upgraded antibody technology, KMD Bioscience can develop high-quality polyclonal antibodies and guarantee positive binding to antigen in ELISA assay.

Alpaca antibodies can withstand elevated temperatures and a wide pH range, which makes them of great interest for basic research and therapeutic applications. Customizable alpaca polyclonal antibody production services are available to serve your specific research goals. KMD Bioscience can also provide antigen design, peptide synthesis, gene expression, antibody purification, identification and antibody labeling services with our independent and advanced antibody engineering platform.  


Alpaca Monoclonal Antibody Production:


Unlike human Igs-consists of two heavy chains and two light chains, llamas, as all members of the camelid family, produce antibodies with an original scaffold only made of heavy chains (IgG2 and IgG3), called heavy Chain Antibody(hcAb), thus promoting binding to structural motifs unreachable before in protein targets, such as viral and enzymatic proteins. The hcAb contains a single variable domain (VHH) and two constant domains (CH2 and CH3). According to the report, cloned and isolated VHHs possess unique properties that enable them to excel in conventional therapeutic antibodies and their smaller antigen-binding fragments in cancer targeting and therapy. VHHs express low immunogenicity, are highly robust and easy to manufacture and have the ability to recognize hidden or uncommon epitopes. The advantages of hcAb are significant: stability maintained even at 60°C, high tolerance to extremes in pH and temperature, and well-expressed in microorganisms such as bacteria and yeast.
