Antibody
Antibody — A Y-shaped immunoglobulin protein produced by B-cells that recognizes and binds specific antigens, used extensively in peptide detection assays.
What Is an Antibody?
An antibody (immunoglobulin) is a Y-shaped protein produced by the immune system that recognizes and binds specific molecular targets (antigens) with high affinity and specificity. In peptide research, antibodies are essential tools for detection (ELISA, Western blot), purification (immunoaffinity chromatography), and characterizing peptide distribution in tissues.
Antibody Types in Peptide Research
- Polyclonal: Multiple epitope recognition. Higher sensitivity. Batch-to-batch variability
- Monoclonal: Single epitope specificity. Reproducible. Required for quantitative assays
- Anti-peptide antibodies: Raised against synthetic peptide immunogens. Used to detect specific protein regions
- Nanobodies: Single-domain antibodies (VHH) from camelids. Small size (15 kDa) with peptide-like properties
