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: 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 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: Chemotaxis describes the movement of cells toward or away from a chemical stimulus in their environment. Cell chemotaxis plays a pivotal role in the progression of cancer and other diseases. CytoSelect Cell Migration Assays are ideal for determining the chemotactic properties of cells. The 8 µm pore size is suitable for most cell types including epithelial cells, fibroblasts, and cancer cell lines.

Description: Cell Biolabs? CytoSelect LDH Cytotoxicity Assay Kit provides a colorimetric format for measuring and monitoring cell cytotoxicity.  The kit contains sufficient reagents for the evaluation of 960 assays in 96-well plates.  Cells can be plated and then treated with compounds or agents that affect cell viability.  Upon cell death, lactate dehydrogenase (LDH), a soluble enzyme found in the cytoplasm, is released into the growth media.  The growth media is then transferred to another plate and the released LDH is then detected with cytotoxicity reagent.  In the presence of lactate substrate (included in the LDH Cytotoxicity Reagent) LDH converts lactate to pyruvate and generates nicotinamide adenine dinucleotide (NADH).   The WST-1 molecule, also present in the LDH Cytotoxicity Reagent, is converted from WST-1 to the orange formazan form.  An increase in cell cytotoxicity is accompanied by increased LDH release and increased colorimetric signal.  The assay principles are basic and can be applied to most eukaryotic cell lines, including adherent and non-adherent cells and certain tissues, depending on LDH expression levels.  The LDH Cytotoxicity Reagent can be used to detect cytotoxicity in bacteria, yeast, fungi, protozoa as well as cultured mammalian and piscine cells.

Description: Cell Biolabs? Cell Contraction Assays (Floating Matrix Model) provide a simple, in vitro system to assess cell contractivity and screen cell contraction mediators. The proprietary Cell Contraction Plate eliminates the matrix releasing step of the conventional contraction assay, providing a faster, higher-throughput method to assess cell contraction.

Description: Cell Biolabs? CytoSelect MTT Cell Proliferation Assay provides a colorimetric format for measuring and monitoring cell proliferation.  The kit contains sufficient reagents for the evaluation of 960 assays in 96-well plates or 192 assays in 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 the yellow tetrazole MTT to the purple formazan form by a cellular reductase (Figure 1).  An increase in cell proliferation is accompanied by an 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: 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: The CytoSelect BrdU Cell Proliferation ELISA Kit detects BrdU incorporated into cellular DNA during cell proliferation using an anti-BrdU antibody.  When cells are incubated in media containing BrdU, the pyrimidine analog is incorporated in place of thymidine into the newly synthesized DNA of proliferating cells.  Once the labeling media is removed, the cells are fixed and the DNA is denatured in one step with a fix/denature solution (denaturation of the DNA is necessary to improve the accessibility of the incorporated BrdU for detection).  Then an anti-BrdU mouse monoclonal antibody is added followed by an HRP conjugated secondary antibody to detect the incorporated BrdU.  The magnitude of the absorbance for the developed color is proportional to the quantity of BrdU incorporated into cells and can be directly correlated to cell proliferation.
