Our Services
To make it easier and better for researchers, BOC Sciences provides cell line development service in a competitive fashion. We have provided a more efficient way to increase the number of new drugs, greatly shorten the R&D cycle, and reduce the development costs.Our team of experts has in-depth cell line development expertise with extensive experience in therapeutic protein development, including difficult-to-express targets. They are able to deliver monoclonal clones with high potency in a cost-effective and timely manner.
- We provide comprehensive services including cell line development from DNA sequence to RCB stability assessment
- BOC Sciences is equipped with a high-throughput automated platform to ensure traceability of the host cell history and cell line generation process
- We also establish advanced cell line development laboratory and clone identification platform
- Our experts can perform cell line matrix quality assessment, including monoclonality validation, productivity and genetic stability assessment, and product characterization
- Leveraging the in-house expression vector engineering expertise, we optimize and design the proprietary vectors with stringent selection to be used with our proprietary host cell lines, resulting in accelerated robust cell line development and increased productivity
- Our proprietary high-performance CHO-K-derived host cell lines have a clear history with complete cell lineage profiling and documentation, and is qualified by microbiological testing
- To meet increasing regulatory requirements, we employ state-of-the-art single cell printers and high-resolution imaging systems to accelerate the single-cell cloning process

Cell Line development process
- Transfection
- Antibody screening/titer ranking
- Single cell isolation and cell viability
- Monoclonality assurance
- Clonal productivity screening and titration
Our scientists introduce a foreign DNA encoding the recombinant protein of interest into host cells, producing stably transfected cells with the ability to express the recombinant protein by integrating foreign DNA into a small portion of their genome
We quantify cell surface expression or secretion of protein-of-interest or secret antibodies (titer ranking) to screen large populations to find rare high-affinity conjugates or high producers
Singe viable cells are isolated and cloned to ensure that cell populations are genetically identical and to reduce expression heterogeneity
We ensure monoclonality of cell lines. In addition, we record images of individual cells and include them in regulatory documents
We use this method to detect the amount of recombinant protein or antibody produced from clonally derived cell lines
