ANTIGEN

Question 1

Any molecular structure that when introduced is capable of Antibody production

Answer 1

ANTIGEN

Question 2

Responsible for the molecular weight of antigen

Note: Molecular weight is important determinant as to whether antigen is elicit

Answer 2

Carrier portion

Question 3

specificity of antigen

Answer 3

Epitope or Determinant

Question 4

Inherent ability of a substance to induce the specific immune response resulting in the formation of immune lymphocytes or antibodies

Answer 4

Immunogenicity

Question 5

The immunogen must be recognized as foreign or non self to induce immune response

Answer 5

Foreigness

Question 6

Antigens that belongs to the host

When it elicit immune response it is termed as “defective immune response/ autoimmune disorder”

Answer 6

Autoantigen

Question 7

Derived from other members of the host/individual species

Common cause of transfusion associated reactions

Answer 7

Alloantigen

Question 8

Derived from other species such as animals, plants and microorganisms

Can be detected inside the laboratory

Answer 8

Heteroantigen

Question 9

These are Heteroantigens that exist in unrelated plants or animals

These antigens are either identical or closely related in structure

When this stimulate immune response antigen can interact with one another

Answer 9

Heterophile antigen

Question 10

tissue transplant. Rich source of antigens

Answer 10

Graft

Question 11

Derived from the px’s/individuals own body

Answer 11

Autograft

Question 12

Derived from identical individual

Answer 12

Isograft/Syngraft

Question 13

Derived from other individual/ Non-identical individual

Answer 13

Allograft

Question 14

Derived from other species

Answer 14

Heterograft/Xenograft

Question 15

The ability to react specifically with the antibody or cell that caused it to be produced

Epitope determines its specificity

Answer 15

ANTIGENICITY/SPECIFICITY
