Custom antibody production at ChinaPeptides is designed for research use. We coordinate antigen preparation, host immunization, bleed or hybridoma screening, and antibody purification.
Customers can supply protein antigens or request peptide antigen synthesis and conjugation as part of the same project. The screening antigen should be stated at kickoff so that we do not immunize with one conjugate and screen only against the carrier.
Timelines depend on host and format. A polyclonal peptide program is typically shorter than a monoclonal campaign. We will not invent a fixed calendar that ignores the biology of the host.
This page is the operational view of an antibody program. Antigen chemistry is described under antigen design. Format choice is described under monoclonal antibody and polyclonal antibody. The antibody hub explains how those pieces sit together.
A production inquiry should name the target, the immunogen type, the preferred host if you have one, and the assay that will accept or reject the reagent. Those four items decide conjugation, screening plates and purification more reliably than a generic request for “a good antibody.”
What is included in a production scope
A typical research scope states how the immunogen is prepared, which host is immunized, how sera or hybridoma supernatants are screened, and whether purification is crude serum, Protein A/G or antigen-affinity. Items that are not written down are not assumed. Therapeutic CMC, diagnostic-kit fill-finish and clinical-grade manufacturing are outside this description.
Peptide versus protein immunogens
A peptide immunogen is useful when a linear epitope is known or when a recombinant protein is unavailable. A protein immunogen is preferred when the native fold is the epitope. Mixing the two without a matching screen is a common reason programs fail. If both are used, say so at the start.
Documentation you should expect
We document what was immunized, what was used for screening and how the antibody was purified. We do not invent titers from unpublished historical averages. If an ELISA titer is reported, it is from the assay that was actually run for that project.
