Flashcards in Lec 3 - Antigens Deck (19):
1

A compound able to combine with elements of acquired immunity

Antigen

2

Proteins, polysaccharides, particulate antigens are blank immunogens

Strong

3

Lipids, steroids, nucleic acids are blank immunogens

Weak

4

Minimal components that are used by the immune system to recognize a particular antigen

Antigenic determinants (epitopes)

5

A b cell producing antibodies can only produce antibodies that are effective against one type of blank

Epitope

6

Larger immunogen means more blank

Complex

7

More complex an antigen, the blank the response

Better

8

Substances that are added to an immunogenic entity can make it more immunogenic

Adjuvant

9

Adjuvant cannot make something that is not originally blank, immunogenic

Immunogenic

10

Thymic independent antigens have responses limited to blank and have poor immunological blank

IgM, memory

11

Haptens can be made immunogenic when attached to something blank

Immunogenic

12

Haptens can or cant be made immunogenic by adjuvants

Cannot

13

Reaction of an antibody with an antigen other than the one that induced its formation

Immunological cross reaction (IMPORTANT)

14

Antigen antibody bonds are not blank

Covalent

15

Forces that can hold antigen antibody complex together

Van der waals, hydrophobic, hydrogen bonds, electrostatic forces

16

Antibody blank binds with the antigen blank

Paratope, epitope

17

Antibody raised against a particular antigen may blank with another antigen if the second antigen contains antigenic determinants found in the first

Cross react

18

Antibody may only recognize an antigen if it is in the proper blank

Conformation (primary, secondary, tertiary)

19

Compound capable of inducing an immune response

Immunogen
