Immunodiffusion Lab Flashcards
1
Q
What interaction is the immunodiffusion laboratory work based on?
A
antigen-antibody interaction
2
Q
What is diffusion?
A
- movement of molecules
- down the concentration membrane
- no ATP use
3
Q
What are the advantages of immunodiffusion tests?
A
- cheap
- signal (+/-) remains for a long time
- no need for immediate evaluation
- antigens and antibodies react through a distance
4
Q
What are the disadvantages of immunodiffusion tests?
A
- long time required to wait for results
- complicated methodology
5
Q
What is the “precipitation line”?
A
The opaque-white line formed between the antigen and antibody sites due to the antigen-antibody complex formation.
