Blood Lecture 3 Flashcards
Antibody =
Alpha
Alpha H =
Antihuman serum
Serum
Clear yellowish fluid obtained when whole blood is separated into its solid and liquid components
Immunology
An antihuman serum is produced by injecting human serum into an animal of another species, such as rabbit, horse, or bird
Antihuman sera react most strongly with what protein?
Human albumin (most abundant protein)
Antigens
Any molecule or pathogen capable of eliciting an immune response
- antigens impart blood types to RBC’S
- more then 15 blood type systems
- ABO & RH most important
- stimulates antibody generation
O - no antigens
A - A antigen
B - B antigen
AB - AB antigen
O - AB antibody’s
A - B antibody
B - A antibody
AB - no antibody
Antihuman serum (alpha H) =
Antibody against human antigen
Immunogen
Immunogen is any agent capable of inducing an immune response and is therefore immunogenic
Soluble proteins are called?
Antibodies or Immunoglobins (Ig)
- Ig make up ~20% of blood protein
- Ig are produced by B lymphocytes
B cells are made in the ___
Bone marrow
T cells are made in the ___
Thymus
Epitope (antigenic determinant)
Part of an antigen that is bound by an antibody
HHb =
Human hemoglobin
Autoimmunity
When an individual mounts an immune response against his or her own
Antiserum
Fluid component of clotted blood from an immune individual that contains a heterogenous collection of antibodies against the molecule used for immunization
Absorption elution
ABO typing from dried blood stains
*use antigens present in sample for typing
Absorption Inhibition
ABO typing from body fluid other then blood
* use antibodies present in sample for typing
Polyclonal
Antibodies produced by injecting animals with a specific antigen
Monoclonal
Collection of identical antibodies that interact with a single antigen site
