RaftNotes describe applications and protocols for use with the CellRaft ^® Technology

The AIR System offers unique advantages over technologies, such as flow cytometry and droplet dispensers, designed to assess cells in suspension. The limitations to other technologies include impacts on cell viability, inability to interrogate small numbers of cells, and reliance on fluorescent markers or staining for cell characterization. To demonstrate the value of the CellRaft technology for use in suspension cell line development, we have established methodologies for attaching suspension cells to the CellRaft Arrays during single cell expansion while still allowing the cells to expand in suspension after the clone of interest has been isolated.

Therapeutic proteins play an essential role in the biological pharmaceutical market and are used in the treatment of many diseases, such as diabetes, cancer, and anemia. One of the main goals in recombinant protein development is the establishment of high-quality monoclonal cell lines that consistently express large amounts of the given protein. Chinese hamster ovary (CHO) cell lines have dominated the industry as commercial hosts for recombinant protein production; however, the process of generating a homogenous CHO cell line is not trivial.
