Recombinant antibody expression enables the production of defined antibody sequences in controlled host systems, offering high reproducibility, batch consistency, and scalability compared to traditional methods. By expressing antibodies from known gene sequences\u2014typically in mammalian cells such as HEK293 or CHO\u2014researchers can obtain antibodies with consistent structure, controlled isotype formats, and appropriate post-translational modifications.<\/p>\n\n

At AbTriva, we provide flexible recombinant antibody expression services to support projects ranging from sequence-to-protein production through to scale-up for functional studies. Our workflows are designed for researchers who require reliable expression of monoclonal antibodies, antibody fragments, or engineered formats, with options tailored to application needs and timelines.<\/p>\n\n

Expression Platforms<\/h2>\n\n

We offer multiple expression systems depending on the antibody format, yield requirements, and downstream application.<\/p>\n\n \n \n \n \n \n \n \n \n
Expression System<\/th>\n Best For<\/th>\n Key Advantages<\/th>\n <\/tr>\n <\/thead>\n
HEK293 Transient Expression<\/td>\n Rapid small- to mid-scale production<\/td>\n Fast turnaround, suitable for screening and early-stage studies<\/td>\n <\/tr>\n
CHO Transient Expression<\/td>\n Higher-yield expression with mammalian processing<\/td>\n Improved scalability, widely used for therapeutic candidates<\/td>\n <\/tr>\n
Stable CHO Cell Line Development<\/td>\n Long-term, large-scale production<\/td>\n Consistent expression, suitable for repeated or high-volume needs<\/td>\n <\/tr>\n
E. coli Expression (for fragments)<\/td>\n Antibody fragments (e.g., scFv, Fab)<\/td>\n Cost-effective, rapid expression (no glycosylation)<\/td>\n <\/tr>\n <\/tbody>\n <\/table>\n\n

System selection depends on antibody format and intended use.<\/p>\n

Mammalian systems are typically preferred for full-length IgG due to proper folding and glycosylation, while bacterial systems are suitable for certain engineered fragments.<\/p>\n\n

Supported Antibody Formats<\/h2>\n\n

We support expression of a range of recombinant antibody formats:<\/p>\n

    \n
  • Full-length IgG (various species and subclasses)<\/li>\n
  • Fab and scFv fragments<\/li>\n
  • Single-domain antibodies (e.g., VHH)<\/li>\n
  • Fc-fusion proteins<\/li>\n
  • Bispecific or engineered antibody formats (upon request)<\/li>\n <\/ul>\n

    If you have sequence information available, we can proceed directly to expression. For projects without sequences, upstream antibody discovery services can be integrated.<\/p>\n\n

    Applications & Use Cases<\/h2>\n\n

    Recombinant antibodies produced through our services are commonly used in:<\/p>\n

      \n
    • Western blot (WB)<\/li>\n
    • ELISA and immunoassay development<\/li>\n
    • Flow cytometry<\/li>\n
    • Immunohistochemistry (IHC)<\/li>\n
    • Functional assays (e.g., blocking or binding studies)<\/li>\n
    • Assay development and optimization<\/li>\n <\/ul>\n\n

      Application-specific validation is not performed by default for all assays.<\/b><\/p>\n

      Validation strategies can be defined based on your experimental requirements and incorporated into the workflow upon request.<\/p>\n\n
