Which antibody increases in infectious diseases, collagen and hematologic disorders? IgG
Which antibody is produced early in an immune response? IgM
Which antibody is the predominant immunoglobulin in secretions? IgA
What is the primary cell membrane immunoglobulin? IgD
Which antibody mediates some types of hypersensitivity reactions? IgE
Dominate type found on all animals in a species Isotype
Found on the immunoglobins of some but not all of a species allotype
individual determinants characteristic of each antibody idotype
what is the sequence of events for a typical immune response Lag phase, log phase, plateau, decline
Which of the following is false in an anamnestic response vs a primary response IgM is predominate
Which type is capable of placental transfer? IgG
ability of an antibody to combine with one antigen vs another specificity
Strength of a bond between a single antigenic determinant and an individual combining site Affinity

non-covalent combination of an antigen with its respective specific antibody Immune complex
What are the types of bonds involved in antigen-antibody reactions Hydrophobic, hydrogen, VanDerWaals
Monocovalent antibodies have also been referred to as what? incomplete antibodies
Antibody engineered to bind to a single epitope, purified from a single cell, are used to classify and identify specific cellular membrane characteristics Monoclonal antibody
Antigens are characterized by : usually Lg organic molecules, glycolipids or glycoproteins, also called immunogens
Antibodies are also referred to as- Immunoglobulins
Accounts for 10% of the Ig pool, largely confined to the intravascular system IgM
