Question
Correctly label the events occurring in the primary and secondary antibody responses indicated Drag the appropriate labels to their respective targets. Antibody titer againRepeat contact with sa decreases over time in Antibody titer decreases IgM antibody is produced Initial antigen exposure rapidly to lgG, produced over time in absence of in low but detectableinitiates primary immune Antibody class switches antigen initiates secondary immune in high titers. antigen. levels. absence of antigen. Primary response Secondary response Mostly IgeG Mostly IgM 100 200 Antigen contact Time (d) Antigen contactExplanation / Answer
the blanks are written subsequently from left to right.
1.initial antigen exposure initiate primage antigen response
2.igM produced in low but detectable level
3.antibody titre decrease over time and absence of antigen
4.releat contact with same antigen produce secondary antigen response
5.antibody class switches rapidly to IgG and produce in high titre
6. antibody titre again decrease over time in absence of antigen
