25
what are the indirect functions of a Ab
inflammation, phagocytosis, and complement
26
what does the fab fragment bind to
Ag
27
what do phagocytic cells recognize on Ab bound to Ag
fc region
28
what is the most common immunoglobulin
IgG
29
what immunoglobulin has the longest 1/2 life
IgG
30
where do you find IgG
plasma of serum
31
which immunoglobulin has the highest molecular weight
IgM
32
which immunoglbulin can cross the placenta
IgG
33
T or F: IgG2 can cross the placenta
F
34
what kind of rxns does IgG cause
agglutination
35
when do maternal IgG stop crossing placenta
at birth
36
what increases the efficiency of phagocytosis when dealing with IgG
phagocytic cells have specific Fc receptors for IgG
37
which immunoglobulin can enter extravascular spaces easily
IgG
38
what kind of immunoglobulin is IgM
macroglbulin
39
where is IgM found
intravascular pool
40
what is the 1st immunoglobulin to respond after attack
IgM
41
what form is IgM
pentamer
42
what holds together the pentamer formation of IgM
J chains
43
T or F: IgM has a short lived response but long lag phase
T
44
when will IgM stop being synthesized
after Ag is gone
45
does IgM have memory
no
46
does IgG have memory
yes
47
what kind of infection is IgM best at fighting
bacterial
48
what is the 1st immunoglobulin to be rearranged
IgM
49
if a lymph has a mmb IgM what does that indicate
immature B Cells
50
where do you find IgA
serum
51
what immunoglobulin is found in breast milk, saliva, sweat, and tears
IgA
52
what immunoglobulin is the first line of defense on mucosal surfaces
IgA
53
where does secretory IgA transport to
MALT
54
where do you find IgD
surface of immunocompetent but unstimulated B lymphs
55
what is the 2nd immunoglobulin to respond after attack
IgD
56
if B lymphs have IgM receptors will an IgG response occur
no
57
b lymphs with both IgM and IgD will respond to what
T cells
58
what immunoglobulin do the lungs and the skin plasma cells produce
IgE
59
what immunoglobulin do mast cells bind
IgE
60
when is the light chain rearranged
not until the heavy chain is completed
61
T or F: the heavy chain is always rearranged 1st
T
62
which light chain is rearranged 1st
kappa
63
after kappa what light chain is rearranged
VJ
64
after the light chain is rearranged what does it join with
mu heavy chain
65
what makes up the mature Kappa light chain
VJ segment and C region
66
what is isotope switching
when a B cell changes what immunoglobulin is being produced
67
what changes are made to constant and variable regions of the ab
constant region changes but variable region stays the same
68
how is the constant region changed in isotope switching
loop is made and then deleted --> new constant region binds
69
t or f: monoclonal ab are not very specific
F
70
what are monoclonal Ab mainly. used for
diagnostic testing and terapeutic purposes
71
where do monoclonal ab come from
single parent ab that has reproduced many times
72
what is a hybridoma
monoclonal ab
73
what makes up a hybridoma
activated B cell with myeloma cell
74
why can't hybridoma make it own DNA
is lacks the enzyme
