Precision Antibody Replication with Hybridoma Introduction

To achieve precise antibody replication from hybridoma cells, strict adherence to specific requirements for antibody production from hybridoma, along with hybridoma screening, is necessary. Additionally, adjusting the specific epitope and antibody characteristics may be necessary to ensure accurate replication.

Precision Antibody Replication with Hybridoma

The process of precision antibody replication involves five main steps, including target epitope determination, immunogen design, immunization, antibody preparation, and epitope determination and validation.

Target epitope determination

The determination of the target epitope is crucial, as subsequent antibody production will depend on this information in addition to research objectives and experimental requirements.

Immunogen design

Immunogen design plays a crucial role in the production of accurate antibodies. The immunogen design determines whether specific antibodies are produced in the immunization preparation, the potency of the antibodies, and the intensity of the post-purification and validation processes.

Currently, the main immunogens commonly used for immunization in the production of antibodies are peptide immunogens and protein immunogens. Peptide immunogens can theoretically produce highly specific antibodies but may require coupling to a carrier to enhance immunogenicity, while protein immunogens are generally more immunogenic but may produce non-specific antibodies.

Immunization

Several immunization routes are available, such as injection immunization, DNA immunization, whole cell immunization, in vitro immunization, subtractive immunization, and others. For specific antibody production, the appropriate immunization route should be selected according to the specific research protocol.

Antibody preparation

To obtain antibodies, we follow the standard process of producing antibodies from hybridomas, starting with obtaining hybridoma cells. Antibodies can also be produced on a large scale using techniques such as in vivo animal production or in vitro culture.

In vivo animal production method

In the in vivo animal production method, most hybridomas for animals are obtained by fusing myeloma cells from BALB/c mice (or LOU/c rats) with splenocytes of the same strain. It is preferred to use the same strain of animals as the one used for the myeloma cells. By inoculating the hybridoma cells into the peritoneal cavity of mice, a large number of ascites monoclonal antibodies can be obtained. This method is simple, economical, and results in a high concentration of antibodies.

In vitro culture method

In vitro culture can take the form of monolayer cell culture or suspension culture. After the cells are cultured in vitro for a certain period of time, the culture supernatant is collected, and the cells and their debris are removed by centrifugation to obtain the desired monoclonal.

Epitope determination and validation of the produced antibody

To validate the obtained antibodies, there are several methods available, including ELISA, western blotting, immunohistochemistry, flow cytometry, protein microarrays, siRNA knockdown, knockout cell lines, knockout mice, and mass spectrometry.
