Development of Semi-Solid Media for Cloning and Screening of Hybridoma Cell Line

Authors

Abstract

Establishment of the hybridoma cell line is an important step for monoclonal antibody production. The screenings of a candidate hybridoma cell clone by limiting dilution is a laborious method and require highly skilled personnel. Currently, a method of easier, faster and more convenient than limiting dilution is cultured in semi-solid culture media was developed. Although, the methylcellulose based semi-solid media kit have available, the culture media kit is very expensive. Moreover, we found that using media based methylcellulose alone unable to generate a 3D colony of the hybridoma cell suggests that there must be other substances in media that are not disclose. In this study, we aimed to develop in-house semi-solid based methylcellulose for generating of 3D colony of the hybridoma cell. The various viscosity substances such as cellulose, methylcellulose, type I collagen and gelatin is used to determine the optimal combination and proportion for semi-solid media to generate 3D colony of the hybridoma cell. The best recipe of the semi-solid media that allow hybridoma cell survival, proliferate and form 3D colonies that remain physically separated from other colonies was 1.5 % methylcellulose, 0.25%gelatin, 1% collagen, in DMEM supplemented with 10% fetal bovine serum.                                                Keywords:  3D cell culture, semi-solid medium, hybridoma cell line
