Term
What is clonal selection and differentiation? |
|
Definition
Ability for a single cell to differentiate into many lymphocytes with different specificities of Abs. Then a specific clone/cell becomes monoclonal specific to an Ag |
|
|
Term
What cells are selected to participate in a specific immune response ? |
|
Definition
Only the T cells and B cells that can bind to the Ag of the pathogen are selected. |
|
|
Term
Describe steps of specific immune response |
|
Definition
-Mixture of (polyclonal Abs) T cells and B cells with different Ag specificities moved towards pathogen
-The Ag has 2 epitopes
-Proliferation of cells with receptors capable of binding epitopes of the Ag creates monoclonal Abs with a single specificity |

Term
What's the basic structure of Abs? |
|
Definition
-2 Heavy chains 50K (4 domains)
-2 Light chains 25 K (2 domains)
-Disulfide bonds link chains together
|
|
|
Term
Where are the L chain and H chain of Abs connected? |
|
Definition
L chains pair with amino terminal portion of H chains and become linked using disulfide bonds |
|

|
Definition
-Fab retains Ab binding site
-Fc retains binding sites for C' and Fc receptors on effector cells |
|
|
Term
What can be done with fragments (pieces) resulting from proteolytic cleavage? |
|
Definition
-Fragments can be used in the lab since they still have binding specificty
-You can modify fragments in lab |
