Antibody[Ab]
- Antibody is glycoprotein or immunoglobulin[Ig] and ⋎-globulin
- Antibody is also termed as H2L2 means antibody consists of two heavy chain and two light chain of polypeptide[in antibody four poloypeptide chain].
- In the structure of antibody variable region is present its variability is according to the specific autigen.
- In variable region complementry sequence for autigen are present where specific autigen bind and this region is named as autigen building site or paratope.
- Rest other past of the antibody consist of constant region.
- Heavy chain & light chain are connected by disulphide linkage.
- Antigen is glycoprotein.
- In antigen a specific region is that where antibody binds
Antibody binds with its specific autigens and perform:-
- Agglutination:-blood gets Agglutinated which slows down the movement of autigen.
- Precipitation :- Antibody binds with antigen & precipitate its.
- Neutralisation:- Antibody neutralises the antigen or toxicity of antigen.
Iysis :-Antigen-antibody ineraction facilitates of lysis of autiger.
