Selection of transfectants (fluorescent clones)
CHO cells were transfected with a GFP expression vector containing a puromycin-resistance marker.
After selection by puromycin for 8 days, surviving cells were dispensed on a Elplasia™* plate.
Single cells were detected by brightfield and fluorescence imaging (Fig. 1).
CELL HANDLER™ picked one of the fluorescent target cells and transferred it to a flat bottom plate.
Six days after transfer, a colony was formed with stable fluorescence, showing the ability of CELL HANDLER™ in accurately picking single-cell transfectants. Also, CELL HANDLER™ helps save time and effort in establishing stable clones and determining their monoclonality.
