Figures & data

Figure 1. Jurkat cells captured on antibody Lewis X Clone-1.

(A) Reference diffraction pattern; (B) object diffraction pattern and (C) hologram diffraction pattern; (D) numerical reconstruction of the hologram rendered the 3D image of the cells; (E) segmentation algorithm marked each individual cell; and (F) 3D image of the Jurkat cells.

Figure 2. Hologram images of Jurkat cells captured on antibody Lewis X Clone-1.

The images are showing control, DMSO and etoposide-treated cells at four different timepoints: 10, 310, 630 and 950 min. The cells are segmented to analyze cell parameters.

DMSO: Dimethyl sulfoxide.
