Monoclonal antibodies are made by the fusion of cells of the immune system with B lymphocytes and myeloma cells.
<h3>What is Hybridoma technology?</h3>
- It is one of the best technologies that is used to produce the monoclonal antibody.
- In this hybridoma technology the B lymphocytes that are antibody producing are isolated from a source after the immunization with a specific antigen and then are fused with myeloma cell line to form hybrid cells that are also called as hybridoma cell lines.
- The hybridoma cell lines are then cultured in the laboratory with specific antigen and then the monoclonal antibodies are produced.
- This can be done in in-vivo or in-vitro condition.
- This method is preferred over all because the production of antibodies by this method is good as the antibodies produced are of high purity and highly sensitive and specific.
- These cell lines can also be preserved for a long time.
- Hybridoma technology has resulted in production of different varieties of monoclonal antibodies with specificity with specific antigens as the monoclonal antibodies are produced by single parental B cells.

Answer: Cell membrane has many properties which is stated below.
Explanation:
The cell membrane allow one cell to communicate with other cell. It is the cell membrane which is directly in contact with the cell membrane of the another cell.
The cell membrane also serves as a channel for the transport of materials from the outside to inside and vice versa.
It also provides stability to the cell. It combines with the carbohydrates and provides immune response and cell recognition.
The brain loses 5-10 percent of its weight between the ages 20 & 90.
