Eosinophils do not have cytoplasm containing large purple/blue-staining granules. Instead, their granules are large but are orange/red in color. These granules are very distinctive for this type of cell, typically making their identification simple.

ll of the following statements describe an eosinophil EXCEPT:

A. Cytoplasm contains large purple/blue-staining granules.

Monoclonal antibodies are monospecific antibodies that are the same because they are made by one type of immune cell which are all clones of a unique parent cell, also called a hybrid cell line, which usually arise from a hybridoma. The fusion of a specific antibody- producing lymphocyte with a myeloma cell will multiply to become a source of pure monoclonal antibody. This is often used in the manufacturing process for monoclonal antibody reagents.

Monoclonal antibodies are usually manufactured in vitro by using:

A. Cultured T cells

B. Human plasma cells

C. Hybridomas

D. Cytotoxic T cell
