Abstract
For establishing cells that secrete antibodies most efficiently (e.g., hybridomas, CHO (Chinese hamster ovary) cells), the screening and subsequent breeding of promising cells have been performed at the single-colony level, which requires several weeks to propagate a substantial number of cells by forming colonies from single cells for evaluation by the conventional assays. However, this screening process lacks high-throughput performance in time and colony numbers. Therefore, development of novel methods is expected to identify single cells secreting higher amounts of antibodies in real-time and in a nondestructive manner without colony formation. In this study, we prepared lipid-labeled antimouse IgG Fc antibodies (capture molecules) that were uniformly displayed on the surface of candidate cells. Secreted nascent antibodies were subsequently sandwiched between capture molecules and fluorescence-labeled antimouse IgG F(ab')(2) F(ab')(2) (detection molecules). This newly developed method is hereinafter referred to as a cell surface-fluorescence immunosorbent assay (CS-FIA). The fluorescence intensity of each cell was found to correlate well with the amount of sandwiched antibodies (from 6.25 fg/cell to 6.40 pg/cell). When about 4 × 10(3) cells of mouse hybridomas were subjected to CS-FIA, we isolated 28 hybridomas showing the highest fluorescence intensity within a day. Furthermore, after propagation of single cells to about 10(5) cells (after 2 weeks), 20 hybridomas were still able to secrete higher amounts (up to 7-fold) of antibodies than parental hybridomas. Our results demonstrate that CS-FIA is a powerful method for the single-cell-based establishment of cells that secrete most efficiently not only antibodies but also various biomolecules.

Abstract
A simple cell labeling method for sorting yeast Pichia pastoris antibody expressing strains is described. A small portion of secreted recombinant antibody retained on the cell surface was labeled with fluorescence detection antibody. The signal intensity of the labeled cell was correlated with the cell's antibody productivity. Using this labeling technique to sort a mixture model induced in the same fermenter where the cells of high producing strain were spiked into a population of a low producing strain at the frequency of 1:100,000, one round of sorting achieved a approximately 5000-fold enrichment of the high producing strain. A variety of P.pastoris strains expressing antibody sorted based on the signal intensity on the cell surface yielded titer improvements by 30% to 300%. Our data demonstrate that Pichia cell surface labeling is a simple, effective and reliable method for sorting Pichia antibody expressing strains for productivity improvement.

Abstract
The selection of high-producing mammalian cell lines represents a bottleneck in process development for the production of biopharmaceuticals. Traditional methods are time consuming (development times often exceed six months) and significantly limited by the number of clones that can be feasibly screened. The market for therapeutic proteins is set to double by 2010, so there is an increasing need to develop methods for the selection of mammalian cell lines stably expressing recombinant products at high levels in an efficient, cost-effective and high-throughput manner. Alternatives include higher throughput methods based on flow-cytometric screening and recently developed automated systems for the selection of high-producing cell lines.

Abstract
The selection of high-producing cell lines is usually time-consuming and labour-intensive. Following transfection, high-producing cells are selected using limiting dilution cloning to prevent non- and low-producing cells from outgrowing high-producing cells, a process that normally takes > 3 months. During this time, the cells have to be screened occasionally to ensure stability of the selected clone. Several new methods for selecting and screening cells using flow cytometry and cell sorting have recently been developed; these include gel microdrop technology, which encapsulates the cells in gelatine beads, and matrix-based secretion assays. This paper reviews these techniques for selecting high-producing cell lines and isolating rare cells.
