2nd Credit Test - Deck 5 Flashcards
(15 cards)
What is used to opsonise particles for testing phagocytosis ?
Latex particles.
Which are anti-inflammatory cytokines ?
IL 10.
How long time does Tuberculin test need to show results ?
48 - 72 hours.
Cloning selection:
Results in proliferation of lymphocytes and may result in apoptosis.
Double positive T cells are positive for both ?
CD4 and CD8.
If markers on whithe blood cells are detected, what methods can we use ?
Magnetic bead separation and FACS.
Exogenous antigen is processed ?
After being presented by antigen presenting cell.
IL-4 produced by Th2 does what ?
Activate B-lymphocyte.
What is the test for hypersensitivity type 1 ?
Western blotting.
Passive immunisation is useful when you want …. response.
Faster
Complement fixation test, the compliment:
Lyses sensitised erythrocytes that are added to the solution if primary antibody doesn’t bind to the antigen.
Adhesion molecule do NOT do ?
Play a role in leukocyte phagocytosis.
Passive immunisation to bacterial toxin would be recommended if:
Exposure to the toxin had already occurred in an unimmunized animal.
What is the spectrum of excitation ?
Range of immune response that can be elicited by various antigens. This includes the activation of different immune cells (like T cells or B cells), the production of antibodies, and the generation of memory cells. The spectrum can vary based on factors like the nature of the antigen, the route of exposure, and the individual’s immune status.
NOT a substrate for enzymoimmunoassays:
Fluorescein.
