The domain of an antibody molecule that is responsible for binding to the antigen is:
a. Fab
b. Fc
c. the carbohydrate region
d. antibody light chain
e. Ig domain
Homework Answers
Answer
a)Fab(fragment antigen binding) domain is responsible for binding to the antigen.there are 2 Fab of Y shape antibody formed after cleavage by protease.
- Fc is the constant fragment at stem of antibody, not responsible for antigen binding.
- no carbohydrate are present in antibody.
- antibody light chain alone cant bind with antigen,it requires heavy variable chain in the form of Fab.
- Ig domain (immunoglobuline like domain) having role in cell to cell recognition ,not in antigen binding.

Alpaca Conventional antibody Alpaca heavy- chain antibody Nanobody/ VH CH1 VH Single domain antibodies are a type of antibody produced naturally by llamas and other camelids, which consist of only a single monomeric heavy chain or light chain but nonetheless can achieve equal binding affinity to antigens as conventional antibodies. A new product, called nanobodies, can be derived from single domain antibodies as depicted in the diagram. While their purpose in these animals is currently unclear, there is large commercial...
