Monoclonal antibodies also called mAbs are lab-manufactured antibodies. While natural antibodies form a diverse group, monoclonal antibodies are all identical and target one specific kind of pathogen such as a virus, bacteria, or cancer cell. The monoclonal antibody is manufactured by genetic engineering technology in CHO cells and the fusion of two types of cells such as B cells and myeloma cells, resulting in hybridoma.

Polyclonal Antibodies

Polyclonal antibodies (pAbs) are a group of different antibodies manufactured by several B cells. As opposed to monoclonal antibodies, they attach to several antigens. They are usually made by injecting an animal and acquiring antibody serum from its blood.

Polyclonal antibodies generally play a key role in research experiments and diagnostic purposes. The process of polyclonal antibody manufacturing involves the immunization of animals, after immunization response blood is collected for serum preparation. The serum goes through a purification step to collect purified antibodies.

Recombinant Antibodies

Storing antibodies- Picture courtesy: POCONO

After antibody manufacturing, their storage is important to maintain sterility and its functioning. The storing standards vary for both short-term antibodies or long-term antibodies. Below are the main storage procedures required for antibody manufacturing:

Storage Form	Duration	Temperature	Description
Short-Term Antibody (Liquid Form) Cold storing practices for monoclonal antibodies- Picture courtesy: K2 Scientific	Less than one month	2-8ᴼC	Short-term antibody is stored in liquid form, mostly in the refrigerator at 4ᴼC. It’s important to use an appropriate buffer like PBS or Tris. A buffer solution will prevent the antibody from becoming too acidic or basic. 0.02-0.05% sodium azide is added into the solution as a preservative to prevent antibodies from microbial contamination.
Long-Term Antibody Storage (Liquid Form) Operating with antibodies- Picture courtesy: Bio-Rad Antibodies	More than one month	-20ᴼC to -80ᴼC	For long term storage, the antibody should be stored at -20 to -80ᴼC. For longer storage, it is essential to divide the antibody solution into smaller tubes. For instance, a 1 ml volume of antibody is to be divided into 10 small tubes. Each tube will be 100 microliters in volume. This process is called aliquot. Aliquoting is the process that mitigate the possibilities of contamination and minimizes freezing and thawing cycles.
Lyophilized (Freeze-Dried Form) Lyophilized antibody vial- Picture courtesy: Immunostep	Months to years	2-8ᴼC Room Temperature	The lyophilized form of antibodies is most suitable for shipment and long-term storage as they remain dry and sealed.
