4 Surprising Facts To Know About Antibody Production

2 Mins read

Industrial antibody production calls for efforts to generate stable cell lines and amounts of pure antibodies that are commercially practicable. These antibodies are necessary for diagnostics, molecular microbiology, and even medicine of specific medical conditions.

Polyclonal antibody production will continue to be a crucial research undertaking, and rabbits will still be a prime species used in this experiment. The schedules and techniques for immunizing rabbits and creating polyclonal antibodies will continue to differ depending on the antibody’s immunogen, adjuvant, and end goal. Here are four things you may not have known about the antibody production process.

Antibodies Are Purified

The antibody purification process entails isolating antibodies from serum, ascites fluid, or a hybridoma cell line culture supernatant – or monoclonal antibody. Purification methods differ from the simplest to the most specific:

  • The simple technique involves the deposition of a subset of total serum proteins, including immunoglobulins.
  • The general method involves the association purification of specific antibody types, such as IgG, without mentioning antigen particularity.
  • The specific approach uses affinity purification of the antibodies in a sample that hatch to a particular antigen molecule.

The purification level needed to get a usable antibody relies upon the antibodies’ intended utilization.

Antibodies are Characterized

Antibody characterization entails three types of activities put into effect at different stages of the antibody production and purification project:

  • Screening is the process of identifying antibody samples with antigen-binding specificity. During the production process, researchers need to use screening to determine which animals and hybridoma clones generate a greater level of antigen-precise antibody. 
  • Titering is the process of measuring antibody concentration and functional assay titer. Antibody titer is related to concentration but refers to the effective potency of a specific antibody sample. Measuring titer typically entails identifying the operative dilution of an antibody sample that is necessary for identification in a particular assay.
  • Isotyping is the process of determining the identity of a monoclonal antibody class and subclass. Isotyping is an essential step in antibody production as it is needed to select an appropriate purification and modification method for the molecule.

Antibodies are Fragmented

Specific approaches using various techniques help purify antibodies, such as fragmentation into more compact antigen-binding groups, conjugation with an enzyme or other detectable labels, and immobilization to stable supports. The classical use approach to antibodies is usually a whole-molecule shape; however, using antibodies with removed nonessential ports can improve some techniques and experiments’ performance. Antibody fragmentation concerns the process of dividing complete antibody molecules and removing parts that aren’t necessary for hatching antigen.

Antibodies are Labeled and Immobilized

Antibodies are created and purified for antigen-specific analysis use. Still, their usefulness in any other technique – such as ELISA, cellular imaging, western blotting, or immunohistochemistry – relies upon the presence of another mechanism that detects the antibody. 

Immunoprecipitation or affinity purification techniques rely on mechanisms for binding or immobilizing antibodies to chromatography media like the beaded agarose resin. Approaches for attaining this include the same notions and chemical processes also used in antibody labeling.

The Bottom Line

Antibody production is a distinguishing feature of the adaptive immune response. Antibodies can neutralize or remove antigens or pathogens, but not many people know what this process entails.
