Micro-Perfusion Flow Cell for Imaging Cultured Cells
Abstract
We present a unique design for a flow cell with a small working volume that allows rapid displacement of media viewed under high power and short working distance objectives. The flow cell has a small internal depth (ca. 0.033 cm) and volume (ca. 0.05 mL) and is easy to handle. Made of Delrin®, the flow cell is biologically inert. We have used the flow cell for fluorescence imaging of PC12 cells loaded with tetramethylrhodamine dextran (TMRD) and other dyes.
