Identification of Antibody Subtypes

In mammals, antibodies are classified into five main classes or isotypes – IgA, IgD, IgE, IgG and IgM. They are classed according to the heavy chain they contain – alpha, delta, epsilon, gamma or mu respectively. These differ in the sequence and number of constant domains, hinge structure and the valency of the antibody. Antibody light chains fall into two classes in mammals, kappa and lambda, with kappa light chains being the more common of the two. Although they are relatively different in protein sequence, they have similar structures and functions. Now, CD BioSciences offers professional Identification of antibody subtypes to meet the specific needs of different customers.

Overall solution

Antibodies of different subtypes have different domains (hinge region, Fc-terminal amino acids, etc.). The difference in domains will affect the physical and chemical properties and biological activities; including antigen binding, immune complex formation, complement activation, half-life Performance, etc. Therefore, in order to achieve the desired effect, antibodies of the appropriate subtype should be selected for downstream experiments. For the preparation of hybridoma monoclonal antibodies, CD BioSciences can provide you with antibody subtype identification services. The scope of identification includes: lgG1, lgG2a, lgG2b, lgG3, IgM, lgA.
