1-3 Flashcards
To create a calibration curve in immunodiffusion tests, we need to know:
‘antigen concentration and diameter of precipitation rings.
Double radial immunodiffusion with antibodies against antigens A and B produced these precipitation lines.
If there is antigen B in well 3, there is antigen [B] in well 2, antigen [A] in well 1, and antigen [B] in well 6.
To determine a titer of antibodies is used a ……………. dilution of serum.
twofold
In ELISA tests substrate is used for:
visualization of the reaction.
Antibodies are added into the agarose for:
single radial immunodiffusion.
Polyacrylamide (PAA) gel is prepared by polymerization after:
pouring of a PAA solution into a cassette created by two glass plates.
What is the characteristic that best defines the acquired immune response?
It exhibits immunological memory.
Pattern recognition receptors (PRR) include which of the following?
Toll-like receptors
A fragment antigen binding (Fab) fragment:
Binds antigen
The basic immunoglobulin (Ig) unit is composed of:
Two identical heavy and two identical light chains
An isolated antigenic determinant that has the ability to react specifically with antibodies but cannot induce their formation is called:
hapten
What is the characteristic that best defines the acquired immune response?
It exhibits immunological memory
