Study Notes
Antigen-Antibody Reactions
- A visible precipitate forms when antigen-antibody complexes aggregate to a size that can be seen, requiring a sufficient concentration of both antigen and antibody.
- Antibodies that aggregate soluble antigens are called precipitins.
Quantitative Precipitation Reaction
- Centrifuging the tubes in a quantitative precipitation reaction separates the precipitate from the supernatant, allowing for measurement of the precipitate.
Precipitin Curve
- A precipitin curve measures the amount of precipitate formed as a function of antigen concentration, providing a quantitative representation of the antigen-antibody reaction.
Antigen Requirements
- For the formation of an Ag-Ab lattice, a multivalent antigen (having multiple epitopes) is required, allowing for the cross-linking of antibodies and subsequent precipitation.
