Worked Solution & Example Answer:The diagram shows a well with a particular human antibody placed in the central well - VCE - SSCE Biology - Question 25 - 2003 - Paper 1
Step 1
1. Describe the role of the antibody in the experiment.
Answer
The antibody placed in the central well is designed to specifically bind to a certain antigen. This interaction allows for the assessment of the presence and concentration of the antigen in the sample wells (PB1, PB2, PB3, and PB4). By analyzing the interactions in these wells, one can determine if the antigen corresponding to the antibody is present.
Step 2
2. What could PB1, PB2, PB3, and PB4 contain?
Answer
PB1, PB2, PB3, and PB4 could contain various substances including different antigens or control substances. Each well may represent a different experimental condition or concentration of an antigen to evaluate its specificity and reactivity with the human antibody in the central well.
