Unconjugated anti-chicken primary antibodies are affinity-purified immunoreagents raised against chicken (Gallus gallus) immunoglobulins or specific chicken proteins and supplied without any detection label. Their unmodified format offers maximal flexibility, allowing researchers to select the most suitable secondary reagents, enzymatic or fluorescent labels, and conjugation strategies for each application. Unconjugated primary antibodies are particularly valuable when high assay sensitivity, multiplexing, custom conjugation, or advanced detection methods are required.
Key Features
- Label-free format: No attached enzymes, fluorophores, or affinity tags, preserving the native antibody structure and antigen-binding characteristics.
- High purity: Affinity-purified using protein A/G or antigen-specific purification methods to minimize background signal and cross-reactivity.
- Multiple formats available: Offered as monoclonal or polyclonal antibodies and supplied in either liquid or lyophilized preparations.
- Flexible downstream applications: Compatible with a broad range of secondary antibodies (species-specific or isotype-specific), conjugation chemistries such as biotinylation, fluorophore labeling, HRP or alkaline phosphatase conjugation, and immobilization strategies.
- Stabilized formulations: Available in buffers containing stabilizers such as BSA and glycerol, with preservative options including azide-free formulations suitable for live-cell and enzymatic applications.
- Quality control validation: Lot-specific testing performed in common applications including Western blotting (WB), immunohistochemistry (IHC), immunofluorescence (IF), ELISA, and flow cytometry (FACS), with Certificates of Analysis (CoA) provided.
Common Applications
- Indirect immunofluorescence (IF) and immunohistochemistry (IHC): Used with labeled secondary antibodies or polymer-based detection systems to achieve flexible signal amplification.
- Western blotting (WB): Indirect detection using labeled secondary antibodies provides enhanced sensitivity and supports multiplex analysis.
- ELISA: Suitable as capture or detection antibodies in sandwich and indirect ELISA formats, particularly when paired with enzyme-conjugated or labeled secondary reagents.
- Flow cytometry (FACS): Enables the use of fluorophore-conjugated secondary antibodies to create customized multicolor panels and improve signal amplification.
- Immunoprecipitation (IP) and pull-down assays: Effective for antigen capture and can be cross-linked to beads to enhance reusability and reduce heavy/light chain contamination.
- Custom conjugation and labeling: Ideal for biotinylation, fluorescent dye labeling, enzymatic conjugation, and site-specific modifications required for advanced research applications.
