Stable Cell Line Development

Different from transient transfection, stable cell line construction means that foreign genes enter the recipient cells and integrate into the chromosomes of the cells, so that the host cells can express the target genes for a long time. Stable cell lines have many applications, such as protein antibody production, signal transduction, drug target research, immunotherapeutic drug development, etc. the expressed protein / antibody has better stability and less batch difference.

DetaiBio provides mammalian stable cell line construction services, and the monoclonal screening process uses unique visual DeepLight^® cell screening platform, which is 2-3 months faster than the traditional monoclonal screening process, shortens the development period of cell lines by over 70%.
