    4.2 Materials and Method 4.2.1 Materials The size of the particle should be large enough to allow three proteins coupling together onto one particle. Therefore, Dynal® MyOneTM 1-μm carboxyl particle (Invitrogen®) and Merck® EM1-100/40 particle were used as the carrier particles. If positive results were seen, the work would be expanded to particles in other sizes, materials and manufacturers, such as Allrun® PM3-050 or Dynal® M270 particles. The proteins chosen for coupling were mouse IgG, streptavidin

    the fluorescent exclusion dye Propidium Iodide (PI) and Fluorescein Diacetate (FDA), which is a cell permeable esterase substrate. This method is based on the fact that PI is permeable to cells only when there is damage to the cell membrane while FDA is a fluorescein molecule with two acetate groups attached via ester bonds. FDA passes the plasma membrane and live cells then cleaves the acetate groups resulting in a photostable fluorescein molecule that remains in the cell. PI and FDA were purchased
