5. Name and compare the biological and chemical character- istics of the five classes of antibodies. 6. Discuss the differences in the biological effector functions of antibodies. 7. Contrast conventional antibody and monoclonal antibody development; conceptualize the procedure for monoclonal antibody ...
In mammals, antibodies are classified into five mainisotypesorclassesaccording to the heavy chain they contain. These are known as IgG, IgA, IgD, IgE, and IgM, where the heavy chain is gamma, alpha, delta, epsilon, or mu respectively. The heavy chains differ in terms of the number and ...
It is possible for two antibodies to have the same binding specificities but be in different classes and, therefore, to be involved in different functions.After an adaptive defense is produced against a pathogen, typically plasma cells first secrete IgM into the blood. BCRs on naïve B cells...

Stoichiometry between antigen and antibody influence immune complex formation and subsequent engagement with Fc domain sensors on host cells and thus effector functions. Antibodies can both provide protection and enhance disease in infections. Emerging tools that systematically probe antibody specificity, affin...
Antibody-secreting cells (ASCs) secrete antibodies that bind to the antigen recognized by their BCR and belong to 1 of 5 main immunoglobulin classes: IgG, IgM, IgA, IgD, and IgE. During the differentiation process, B cells enter a germinal center, which is a specialized structure where B ...
At the protein level, each immunoglobulin (antibody) is formed of heavy chains and light chains. Based on size and amino acid composition, the heavy chains are divided into five isotypes (classes) represented by the Greek letters α, δ, ε, γ, and μ, which are representative of the ...

The colored text is used to separate the different classes of transition. The time complexity of the breadth-first search can be expressed as O(∣V∣ + ∣E∣), where ∣V∣ and ∣E∣ are the numbers of vertices and edges, respectively. In the case of antigen patterns, the former ...
Monoclonal antibodies are a growing class of targeted cancer therapeutics, characterized by exquisite specificity, long serum half-life, high affinity and immune effector functions. In this review, we outline key advances in the field with a particular focus on recent and emerging classes of engineere...
