Description: The CytoSelect Cell Viability and Cytotoxicity Assay Kit provides a simple format for monitoring cell viability via metabolic activity. Live cells are detected with either MTT (colorimetric detection) or Calcein AM (fluorometric detection). Dead cells are detected by EthD-1 reagent (fluorometric). All 3 detection reagents are included, along with Saponin (a cell death initiator). Prior to the assay, cells may be treated with compounds or agents that affect cell viability. This kit is suitable for eukaryotic cells, not yeast or bacteria.

Description: Cancer cell transmigration, particularly extravasation, is an important step in cancer metastasis. It is the final step in a cascade of interactions between cells and the endothelium. CytoSelect Leukocyte Transmigration Assay provides a robust system for the quantitative determination of transmigrations and interactions between endothelium and leukocytes. Migratory cells may be quantified on a fluorescence plate reader. Kits use 24-well plates with 3 µm pore size membrane inserts.

Description: Our CytoSelect 384-Well Cell Transformation Assay uses a modified soft agar 3D matrix to support the formation of colonies by neoplastic cells. Quantitation of cell transformation is performed on a fluorescence plate reader.

Description: Traditionally scratch assays have been used to study cell migration, cell proliferation and wound healing. However, these assays lack a consistently defined wound gap and can result in high inter-sample variation. Our CytoSelect 24-Well Wound Healing Assay provides a much more consistent method to measure cell migration across a wound field gap in vitro. Proprietary inserts generate a consistent 0.9mm wound gap between the cells. Cells may then be treated or monitored for proliferation or migration across the wound field by imaging samples at fixed time points or by time-lapse microscopy.

Description: The ability of malignant tumor cells to invade normal surrounding tissue contributes in large part to the morbidity and mortality of cancers. Cell invasion requires several distinct cellular functions including adhesion, motility, detachment, and extracellular matrix proteolysis. Our CytoSelect Cell Invasion Assays utilize precoated inserts to assay the invasive properties of tumor cells. Invasive cells can be quantified in 24-well plates on either a standard microplate reader or a fluorescence plate reader. Inserts are precoated on the top of the membrane with ECM matrix gel (basement membrane), a protein mix isolated from EHS tumor cells.

Description: Phagocytosis can be assayed by measuring the engulfment of a cell "substrate". However, traditional assays require tedious cell counting under a microscope. Our CytoSelect 96-Well Phagocytosis Assay, Red Blood Cell Substrate provides a more accurate, user-friendly, high-throughput alternative to the standard phagocytosis assay. The assay may be adapted for use with 24-well or 48-well plates.

Description: Cell Biolabs? CytoSelect Cell Proliferation Assay Reagent (Fluorometric) provides a fluorometric format for measuring and monitoring cell proliferation. Cells can be plated and then treated with compounds or agents that affect proliferation.  Cells are then incubated with the proliferation reagent.  Upon entering metabolically active live cells, the non-fluorescent proliferation reagent is converted into a bright red fluorescent form. An increase in cell proliferation is accompanied by increased fluorescent signal, while a decrease in cell proliferation (and signal) can indicate the toxic effects of compounds or suboptimal culture conditions.  The assay principles are basic and can be applied to most eukaryotic cell lines, including adherent and non-adherent cells and certain tissues.  This cell proliferation reagent can be used to detect proliferation in bacteria, yeast, fungi, protozoa as well as cultured mammalian and piscine cells. The kit contains sufficient reagents for the evaluation of 960 assays in ten 96-well plates or 192 assays in eight 24-well plates.

Description: Cell Biolabs? CytoSelect WST-1 Cell Proliferation Assay Reagent provides a colorimetric format for measuring and monitoring cell proliferation.  The 10 mL volume is sufficient for the evaluation of 960 assays in ten 96-well plates or 192 assays in eight 24-well plates.  Cells can be plated and then treated with compounds or agents that affect proliferation.  Cells are then detected with the proliferation reagent, which is converted in live cells from WST-1 to the formazan form in the presence of cellular NADH and an electron mediator. An increase in cell proliferation is accompanied by increased signal, while a decrease in cell proliferation (and signal) can indicate the toxic effects of compounds or suboptimal culture conditions.  The assay principles are basic and can be applied to most eukaryotic cell lines, including adherent and non-adherent cells and certain tissues.  This cell proliferation reagent can be used to detect proliferation in bacteria, yeast, fungi, protozoa as well as cultured mammalian and piscine cells.

Description: Many solid tumors contain heterogeneous populations of normal and cancerous cells. Separation of these cell populations is key to an accurate assessment of the true genotypic and phenotypic differences between normal and tumor cells. Our CytoSelect Clonogenic Tumor Cell Isolation Kit uses a proprietary semisolid agar medium to facilitate formation of colonies by cells from solid tumors. Colonies are grown in either a 6-well plate or a 35mm culture dish. These colonies are isolated away from single (i.e. normal) cells by size filtration. The viable cells from these colonies can be easily recovered for further analysis.

Description: Leukocyte or tumor cell interactions with vascular endothelium consist of a cascade of processes including the firm attachment of cells to endothelial cell adhesion molecules. The CytoSelect Leukocyte Epithelium Adhesion Assay provides a robust system for the quantitative determination of interactions between leukocytes and epithelium. Adherent cells can be easily quantified on a fluorescence plate reader.

Description: Adhesion to the extraceullular matrix is essential for the survival and propagation of many adherent cells. Apoptosis resulting from the loss of adhesion to the ECM is known as anoikis. Anoikis is involved in the physiological processes of tissue renewal and cell homeostasis. Our CytoSelect Anoikis Assays allow you to quantify and monitor anoikis in cells using a precoated plate. Live cells can be viewed under a microscope and quantified on a plate reader by MTT (colorimetric) or Calcein AM (fluorometric); both reagents are included in the kit. Dead cells are detected with the red EthD-1 reagent, also included.
