WorksheetsElisa/Immune system lab
Total questions: 58
Worksheet time: 38mins
bind sample to well
add primary Ab and wash
add secondary Ab/enzyme and wash
add substrate
Why are enzymes used in this immunoassay?
for color change
to protect the antigen
to denature protein
to speed the reaction
During the virtual lab (and eventually our ELISA lab), you will prepare a set of dilutions...why?
serial dilutions help determine the level of antibodies present in a sample
serial dilutions identify the pathogen
serial dilutions help determine the level of macrophages present
serial dilutions identify the killer T cells present
The first layer on the ELISA plate was the
antigen
antibody
virus
substrate
The A in ELISA stands for
allele
antigen
assay
antibody
What we attempting to detect in this ELISA?
SARS
HIV
HPV
MRSA
Which one of the following is NOT one of the nonspecific body defenses?
mucous membranes
antibody production
natural killer cells
inflammatory response
Long lived B cell clone members that do not become plasma cells but are capable of an immune response against the same antigen at a later time are called:
killer cells
natural killers
helper cells
memory cells
What is the term for a protein that can put holes in bacteria and cause them to lyse?
Phagocyte
natural killer cell
complement
interferon
A secondary immune response will be faster when...
The individual has encountered the pathogen already
The individual's macrophages are on high alert
The individual has encountered the pathogen and has memory B cells circulating
Antibodies are produced by T cells
What is the function of B cell
Proliferate plasma cell and memory B cell
Release antibodies
Secrete interleukin-2
Produce interleukin-1
T lymphocyte is used in which immune response
Humoral Immune Response
Cell Mediated Immune Response
Antibody-Mediated Immune Response
How do T cells differ from B cells?
T cells fight pathogens by killing pathogens directly, while B cells fight pathogens by making antibodies.
T cells only make memory cells, and B cells only make antigens
T cells fight pathogens by making antibodies, while B cells fight pathogens by killing pathogens directly.
T cells can only fight off pathogens the body has encountered once, and B cells can fight off any pathogen the body comes across.
Which of the following is a pathogen?
Bacteria only
Viruses, bacteria, fungi, and Protista
Viruses and bacteria
______________________ attack and kill infected cells
Helper T Cells
B Cells
Cytotoxic T Cells
Acquired immunodeficiency syndrome
Koch's Postulates
Immunity
Vaccine
Autoimmune disease
AIDS
___: immune response: uses B cells
Humoral
Inflammation
Histamine
Tonsils
A positive ELISA test always indicates that an individual is sick.
True
False
An HIV test looks for these "markers" that signal the presence of HIV
Microbes
Pathogens
Antibodies
Red Blood Cells
Antibodies are defined as
Special molecules produced by the bodies lymph nodes
Special glucose molecules produced by the bodies immune system
Special proteins produced by the bodies immune system
None of the above
The Elisa Test is typically the first test completed in order to diagnose HIV
True
False
