We offer a collection of pre-made, high-quality recombinant antibodies that represent the highest standards of quality and purity for your research use.  All our recombinant antibody products are expressed in mammalian cells under animal component-free condition, purified to the highest quality possible, and formulated into the carrier-free buffer compatible with downstream in vitro and in vivo bioassays. We also provide a suite of custom solutions for your antibody R&D, including our one-stop shop "Gene-to-Antibody" bundled services, starting from antigen preparation, hybridoma monoclonal antibody discovery, antibody humanization and engineering to custom-scale antibody production. 

You can browse our recombinant antibody products by applying different filters listed on the right, such as "Molecule Class", "Gene Family", and "Pathway/Disease" for their targeting antigens, or featured product list below.  Alternatively you can search to retrieve antibodies against your antigen of interest by its encoding gene symbol or synonym.  If you cannot find your antibody or need a different quantity/format/variant, we can generate it as a custom service project.  We will construct and express your antibody with custom choice of species, isotype, subclass, or fragment.  You can simply provide us with the DNA/amino acid sequences, we will deliver to you ready-to-use antibodies. To learn more and request a quote, please go to our "Antibody Services".
