Analyzing the Role of Different Adhesion Molecules and Chemokines Involved in Inflammation

Cellix Ltd
24 Sept 2012

This application note analyzes the role of different adhesion molecules and chemokines involved in various stages of inflammation under physiological flow conditions. Using Cellix’s biochips and Mirus pumping system, THP-1, monocyte and PBMC adhesion to VCAM-1; THP-1, monocyte and PBMC rolling on E-selectin; and respective adhesion blockades is investigated. THP-1 adhesion to HUVECs, correlating adhesion assay results with adhesion molecule expression levels on HUVECs from flow cytometry data, is also investigated. This method also investigates THP1 and PBMC adhesion to TNFα stimulated HUVECs and the effect of blocking antibodies (anti-VCAM-1; anti E-selectin; anti ICAM-1 and a combination of all three).

Vena8 Fluoro+ Biochip: microfluidic flow chamber

Cellix Ltd

The Vena8 Fluoro+™ biochip is ideal for studying cell receptor-ligand interaction and is compatible with confocal microscopy. As cells flow through the microcapillary of the Vena8 Fluoro+™ biochip, the cell surface receptors may interact with adhesion molecules or ligands which coat the microcapillary walls. Ideal for use with fluorescence immunostaining, confocal microscopy and for applications such as thrombosis.

Cell Adhesion AssaysCell adhesion assays are used to quantitate attachment and analyze the molecular mechanisms for extracellular matrix adhesion, cell migration and sensitivity to inhibitors. Find the best cell adhesion assay equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Cell / Tissue CultureCell culture or tissue culture is used to study the biology of cells or tissues and to isolate cellular products in an environment which can be manipulated and well defined. Accurately control your culture environment with bioreactors or culture incubators, bind your cells to a surface or together with an extracellular matrix. Distinguish cell types with differential media or proliferate cells with certain characteristics using selective media. Enrich your media with supplements such as growth factors, sera and vitamins. Find the best cell and tissue culture products, kits and equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Lab-on-a-ChipLab-on-a-chip (LOC) technology uses microfluidic chips, such as microarrays, to perform biochemical assays on a small scale. Benefits of lab-on-a-chip include the small volume of sample required as well as the speed of analysis. In selecting lab-on-a-chip devices consider the assay, cost, reliability, sensitivity and signal to noise ratio.Cell Lines Stem Cells and Primary CellsPrimary cell cultures, established cell lines and stem cells are vital for <i>in vitro</i> and <i>ex vivo</i> experimentation. High-quality cells, optimized for your applications, alongside optimized cell substrates, growth medium and supplements, are critical for experimental success. Explore a range of cells suitable for your applications, including isogenic cell lines, competent cells, induced pluripotent stem cell (iPSC)-derived cell lines, fungal/bacterial/mammalian cell lines, stem cells and cancer cell lines. Find the best cells for your research in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Cell-Based AssaysCell-based assays are used to monitor the presence, quantity and activities of a desired cellular analyte including drug molecules or biomarkers. This can reveal information on cell health (apoptosis, cytotoxicity, viability and proliferation assays), cell metabolism, cell migration and cell signaling mechanisms. Find the best cell-based assay products, kits and equipment with our peer reviewed product directory: compare products, check customer reviews and receiving pricing direct from manufacturers.PumpsLaboratory pumps are devices used to move liquids and gases by vacuum or positive displacement. The pressures/vacuums generated are determined by the type of pump used. High vacuum pumps include diffusion, ion, roots and turbopumps; for primary/medium vacuum applications see rotary vane pumps, scroll & diaphragm pumps. For the positive displacement of liquids explore a range of syringe and peristaltic pumps, as well as fluid aspirators.
