An antibody displayed phage collection (SBAE-2R), screened from a human synthetic phage antibody library (Fab 21ox), was used for the determination of dextran. The dextran-binding affinity was determined by serologically specific transmission electron microscopy (TEM) and a paper dipstick assay. The phage collection was distributed over the dextrancoated grids with 39$pm$25 phages/$mu$m$^2$ on the grids. Phages were not seen on dextran-coated grids exposed to the Fab 2lox phage library. The phage collection (SBAE-2R) produced 54$pm$3 color normalized intensity (N.I.) from 125 ppm to 1,000 ppm of dextran and 5$pm$1 (N.I.) for 63 ppm of dextran in a paper dipstick assay. This research extends the analytical options for dextran analysis by antibody displayed phage with a minimum of equipment usage.
