Expert antibody production is a complex process that involves the use of distinctive protocols. It takes an experienced team of scientists and specialized equipment to ensure high quality products. Moreover, the different steps of this process must be carried out in accordance with strict and specific conditions.

The first step in the process of developing monoclonal antibodies is the expression of purified antigens in cell lines. The choice of cell line depends on the application and the desired product titer. The choice of media formulation is also an important factor, as it influences cell growth and protein expression. Laboratories usually test various media compositions to determine the optimal one for each cell line.

Once the cells are in culture, several methods can be used to increase the titer. Some of the techniques include the addition of specific supplements, such as nutrients, growth factors and autocrine factors. Others involve the use of additives that modulate post-translational glycosylation and fucosylation, which can lead to increased cellular uptake and higher antibody yields. In addition, some techniques increase cell density by increasing the size of the culture vessel.

Once the titer has reached the target value, additional tests can be performed to ensure that the final mAb meets the requirements for its therapeutic applications. These tests can include SDS-PAGE, SEC-HPLC, endotoxin, and WB. Sterility testing is also required to ensure that the final mAb will not be contaminated by microorganisms. After this, the product can be packaged in sterile containers and stored in a temperature-controlled environment until it is ready to be used.
