Polyclonal antibodies
Polyclonal antibodies (pAbs) are a mixture of antibodies produced by different B cell clones in the body. These antibodies recognize and bind to multiple epitopes on a single antigen, offering advantages in certain research and diagnostic applications. AffiNEURO polyclonal antibodies are essential tools for comprehensive neurobiological studies due to their high sensitivity and robust detection capabilities.
Production and Characterization
The production of polyclonal antibodies involves the immunization of animals, such as rabbits, goats, or mice, with the target antigen. The animal's immune system generates a diverse array of antibodies against various epitopes of the antigen. Blood is collected from the immunized animals, and the antibodies are purified from the serum.
Characterization of polyclonal antibodies involves:
- ELISA (Enzyme-Linked Immunosorbent Assay): Measures the antibody's overall affinity and titer against the antigen.
- Western Blot: Confirms the recognition of antigen epitopes in a denatured form.
- Immunohistochemistry: Assesses the antibody's ability to bind to antigens within tissue sections.
- Affinity Purification: Ensures the antibodies are specific to the target antigen, removing non-specific antibodies.
Applications in Neuroscience
Polyclonal antibodies in AffiNEURO are widely used in various neuroscience research and diagnostic applications due to their broad epitope recognition. Key applications include:
- Detection of Neurodegenerative Disease Markers:
- Alzheimer's Disease: Detection of amyloid-beta (Aβ) and tau protein in brain tissues and fluids.
- Parkinson's Disease: Identification of alpha-synuclein aggregates in neuronal cells.
- Neuroinflammation Studies:
- Detecting and quantifying pro-inflammatory cytokines (e.g., IL-1β, IL-6, TNF-α) to study neuroinflammatory processes.
- Signal Transduction Pathways:
- Investigating various signaling molecules and pathways involved in neuronal communication and plasticity.
- Neuro-oncology:
- Identifying and characterizing tumor-specific antigens in brain cancers, such as glioblastoma.
Advantages of Polyclonal Antibodies
- High Sensitivity: Recognize multiple epitopes, enhancing the likelihood of detecting the target antigen even if some epitopes are masked or altered.
- Robust Performance: Less affected by small changes in the antigen structure, providing reliable results in various experimental conditions.
- Cost-Effective Production: Generally less expensive to produce compared to monoclonal antibodies.
