Host
Host antibodies, derived from species such as mouse, rabbit, goat, rat, and chicken, are essential for immunology, diagnostics, and therapeutic research. Combined with recombinant biotechnology, these antibodies are engineered for higher specificity, reproducibility, and consistent performance in applications like ELISA, Western blot, immunohistochemistry, and flow cytometry. By integrating natural host immune responses with recombinant protein technology, researchers gain reliable tools for biomarker detection, drug discovery, and molecular biology workflows.
Chicken
When raised in chickens, antibodies show unique advantages compared to mammalian hosts. These IgY polyclonal antibodies recognize human, goat, and rabbit proteins with minimal interference from mammalian IgG, which improves clarity in assays. They are commonly delivered as purified fractions, often conjugated with HRP, biotin, or fluorescent dyes, and are applied in ELISA, Western Blot, and immunohistochemistry. Research studies highlight chicken-derived antibodies as reliable reagents for diagnostics and protein analysis, especially when cross- reactivity must be avoided.
E Coli
Recombinant proteins from Escherichia coli are used in research because this bacterium grows fast, is easy to handle, and produces proteins such as interleukins in large amounts. Scientists rely on E. coli expression for antibodies, cytokines, and other proteins needed in immunology, cancer, and infectious disease studies. Data from NIH and NCBI publications confirm that E. coli remains one of the most efficient and reliable hosts for protein production.
Goat
Goat Polyclonal Antibodies are affinity-purified immunoreagents generated in caprine hosts, designed to recognize IgG heavy and light chains (H+L) from human, rabbit, and mouse species with high binding fidelity. By capturing multiple epitopes within the immunoglobulin domains, these secondaries ensure robust signal amplification and resilient detection even under variable assay conditions. The portfolio encompasses HRP, biotin, FITC, Cyanine, and Alexa Fluor conjugates, enabling integration into chemiluminescent, chromogenic, and multiplex fluorescent platforms. Cross-adsorbed variants minimize non-specific reactivity across phylogenetically related species, thereby preserving data integrity in complex multi-species panels. Validated for Western blotting, IHC, ICC/IF, and flow cytometry, these antibodies deliver reproducible sensitivity, and experimental versatility suited for both routine assays and advanced translational.
Mouse
Mouse Anti-Human Antibodies (Monoclonal & Polyclonal), The mouse (Mus musculus) is the standard host for antibody production because its immune system is well studied and reacts strongly to human proteins. Mouse monoclonal antibodies give single-epitope recognition with high reproducibility, making them reliable for Western blot (WB), immunohistochemistry (IHC), and flow cytometry (Flow). Polyclonal antibodies from mouse serum bind several epitopes, giving stronger signals and better detection of low-abundance targets. Mouse hosts are used in hybridoma technology, which allows stable and consistent antibody production. These antibodies are available in HRP, biotin, and FITC conjugates, supporting flexible use in protein detection, tissue staining, and cell analysis across many research fields.
Rabbit
Gentaur Rabbit Polyclonal Antibodies are affinity-purified, high-affinity reagents derived from rabbits, generating multi-epitope recognition for enhanced sensitivity in Western blot, IHC (paraffin-embedded or frozen sections), ICC/IF, and flow cytometry. Available in versatile conjugate formats including HRP, biotin, FITC, Alexa Fluor dyes, and alkaline phosphatase, these antibodies support both enzymatic and multiplexed fluorescent detection. Validated for human, mouse, and rat proteins, they deliver reliable performance across species. Engineered for precision and broad applicability.
Rat
Rat Monoclonal Antibodies: Essential Tools for Advanced Immunoassays Rat monoclonal antibodies (mAbs) offer high specificity and affinity, making them ideal for applications such as Western blotting, immunohistochemistry (IHC), and flow cytometry. These antibodies can be conjugated with HRP, biotin, FITC, and other labels to enhance sensitivity and versatility. Available in various clones, they are customizable for specific needs, ensuring precise detection of target antigens. Whether used for protein analysis or cell profiling, rat mAbs provide reliable and reproducible results, advancing your research in molecular biology.
Sheep
Sheep Polyclonal Antibodies are applied in Western Blot, immunohistochemistry (IHC), and flow cytometry (FACS) for the detection of anti-human, anti-rabbit, and anti-rat protein epitopes. These antibodies can be conjugated with HRP, biotin, or FITC, enabling flexible detection strategies in both clinical and research settings. By combining sheep-derived polyclonal antibody diversity with the specificity of monoclonal clones, researchers obtain reliable reagents for protein characterization across multiple hosts.
