Brightfield and Fluorescence Imaging using 3D PrimeSurface® Ultra-Low Attachment Microplates

Culturing cells in three-dimensions (3D) has become a well established approach as it is more representative of the in vivo environment than traditional two-dimensional (2D) cultures. Allowing cells to interact with each other in a spheroid creates a micro-environment which mimics in vivo tissue and is a better model for examining the effect of drugs in cancer. Developing uniform spheroids becomes especially important as it forms the basis for robust and reliable assays. S-BIO PrimeSurface® cultureware are ultra low attachment (ULA) dishes and plates that promote scaffold free, self assembly spheroid formation. The plates are pre-coated with a proprietary hydrophilic polymer that enables spontaneous spheroid formation of uniform size. PrimeSurface 96 and 384 ULA plates have good optical clarity making them highly suitable for brightfield and fluorescent imaging. Imaging technologies such as the BioTek Cytation™ 5 allows researchers to study not only spheroid proliferation through brightfield imaging, but also phenotypic events such as hypoxia, apoptosis, or necrosis induction through the use of fluorescent probes and fluorescence imaging. Incorporation of z-stacking and projection techniques in the Gen5™ Microplate Reader and Imager Software create in-focus images of spheroidal cells, allowing accurate, robust, and repeatable determination of the effect of test molecules or conditions. In this app note, we present data generated with BioTek Cytation 5 using PrimeSurface ULA plates to develop simple robust spheroid assays for brightfield and fluorescence imaging.
