EnglishWhat Antibody Production and Engineering Services Does BiologicsCorp Provide?
Updated
BiologicsCorp provides antibody-related services across three areas: production (monoclonal, polyclonal, and recombinant antibodies), characterization and sequencing (antibody pairing, labeling, hybridoma sequencing, de novo antibody sequencing), and engineering (scFv construction, Fab antibody, chimeric antibody). If your project needs a custom antibody, a recombinant antibody format, or sequence information from an existing hybridoma, the service list below covers the typical entry points. Specific pricing and turnaround times are not stated on the site, so those need to be confirmed through a quote request.
Antibody Production Services
These services cover generating antibodies from an immunogen or from a supplied gene sequence.
- Monoclonal antibody production — generation of a single-specificity antibody, typically for consistent, reproducible binding across experiments.
- Polyclonal antibody production — generation of a mixed antibody population, useful when broad epitope recognition is acceptable or preferred.
- Recombinant antibody production — expression of antibodies from gene sequences, including IgG, IgE, and IgD, as well as chimeric formats (scFv, discFv, Fab, sdAb, and VHH) and Fc fusion protein expression.
The recombinant route is the relevant choice when you already have a sequence, need a defined antibody format, or want to move away from hybridoma-based production. The company describes this as a "gene to recombinant antibody" pipeline.
Antibody Characterization and Sequencing Services
These services apply when you have an existing antibody or hybridoma and need information about it rather than a new reagent.
- Antibody pairing — identifying or matching antibody pairs, which matters for sandwich assay development.
- Antibody labeling — conjugating antibodies for detection or assay use.
- Hybridoma sequencing — recovering sequence information from an existing hybridoma line.
- De novo antibody sequencing — determining antibody sequence without a hybridoma, for example from a purified protein sample.
Hybridoma sequencing is the usual starting point if you have a working cell line but no sequence record. De novo sequencing is the alternative when the cell line is unavailable or lost.
Antibody Engineering Services
Engineering services modify or rebuild an antibody into a different format.
- scFv construction — building single-chain variable fragments, commonly used for smaller reagents, fusion constructs, or screening formats.
- Fab antibody — producing the antigen-binding fragment rather than the full-length IgG.
- Chimeric antibody — combining variable regions from one source with constant regions from another.
These formats are typically chosen when full-length IgG is too large, when tissue penetration or clearance properties matter, or when a non-native format is required for a specific assay.
Related Capabilities That Support Antibody Work
Antibody projects often depend on adjacent services the site also lists:
| Capability | Relevance to antibody projects |
|---|---|
| Mammalian expression system | Transient or stable expression for recombinant antibodies and proteins |
| Bacterial, yeast, insect expression systems | Alternative expression hosts for protein and antibody fragments |
| Stable cell line construction | Cell lines for research or production use |
| Protein interaction analysis (GST pull-down, co-immunoprecipitation, bio-layer interferometry) | Binding and affinity characterization, including Ka, Kd, and KD determination |
| Antibody products catalog | Off-the-shelf polyclonal antibodies, including CD markers, tag antibodies, loading controls, and phospho-specific antibodies |
If your goal is assay development rather than a new reagent, the interaction analysis services and the catalog antibodies may be more directly useful than custom production.
How to Choose Among These Services
- You have an immunogen and need an antibody: start with monoclonal or polyclonal production.
- You have a sequence and need a defined format: use recombinant antibody production.
- You have a hybridoma but no sequence: use hybridoma sequencing.
- You have purified antibody but no cell line: use de novo antibody sequencing.
- You need a smaller or modified format: use antibody engineering (scFv, Fab, chimeric).
- You need binding data: use the protein interaction analysis services.
The site does not publish prices or delivery timelines for these services. It does state that its bacterial expression system is offered with "no delivery, no charge" terms and pricing described as 30% below the industrial average, but that claim is tied to the bacterial expression service specifically and should be verified for any antibody project.
