The CHEMICON Cell Invasion Assay is performed in a 96-well invasion plate based on the Boyden chamber principle. This plate contains 96 inserts; each insert contains an 8 μm pore size polycarbonate membrane coated with a thin layer of polymerized collagen. The collagen layer occludes the membrane pores, blocking non-invasive cells from migrating through. Invasive cells, on the other hand, migrate through the polymerized collag…

CHEMICON®'s Cell Transformation Detection Assay is an anchorage-independent growth assay in soft agar, which is considered the most stringent assay for detecting malignant transformation of cells. For this assay, cells (pre-treated with carcinogens or carcinogen inhibitors) are cultured with appropriate controls in soft agar medium for 21-28 days. Following this incubation period, formed colonies can either be analyzed morphol…

Tube formation is a multi-step process involving cell adhesion, migration, differentiation and growth4. The formatio…

The CHEMICON® In Vitro Vascular Permeability Assay is performed in a 24-well tissue culture plate with 12 cell culture inserts. The inserts contain 1.0 μm symmetrical pores within a transparent polyethylene membrane. The high pore density membranes permit amplified rates of basolateral diffusion with molecules of interest for permeability assays. The membrane is tissue culture treated on both sides for cell growth. Within CHE…

The CHEMICON® Endothelial Cell Adhesion Assay kit (ECM645) allows the researcher to test a variety of cell types that interact with activated or inactivated endothelial cell layers. The CHEMICON® Endothelial Cell Adhesion Assay kit includes a 96 well tissue culture treated fluorescence microtiter plate and reagents that allow for large-scale screening and quantitative comparison of multiple samples/cell line adhesion to an en…

ECM675 uses purified chicken type I collagen in 6mM acetate buffer pH 7.0. The product is 99.9% pure native atelomeric avian collagen. Approximately 85% type I and 15% type III collagen protein. The material has been specially prepared to maintain its native state as much as possible. The telomeric ends of the collagen I have been enzymatically removed. Since most of the species identity is found within the telomeric ends, our…

The Multidrug Resistance Direct Dye Efflux Assay Kit includes two of the best characterized and most commonly used multidrug resistance ABC transporter substrates, DiOC2(3) and rhodamine 123. The kit enables researchers to directly assess the functional activity of the MDR1, MRP1 and BCRP membrane pumps in living cells under physiologic conditions by directly measuring the relative fluorescence of cell populations that activel…

CHEMICON's Actin Cytoskeleton and Focal Adhesion Staining Kit is a very sensitive immunocytochemical tool that contains fluorescent-labeled phalloidin (TRITC-conjugated phalloidin) to map the local orientation of actin filaments within cell and a mouse monoclonal antibody to Vinculin that is very specific for the staining of focal contacts in cells.

Chemicon's Mast Cell Degranulation Assay Kit provides a simple and convenient means for assaying tryptase activity. The assay is based on spectophotometric detection of the chromophore p-nitroaniline (pNA) after cleavage from the labeled substrate tosyl-gly-pro-lys-pNA. The free pNA can then be quantified using a spectrophotometer or a microtiter plate reader at 405 nm. A pNA Standard is provided as a comparison control.

CHEMICON's NS220 Neurite Outgrowth Assay Kit (3 µm) utilizes microporous tissue culture insert technology from EMD Millipore and is based on the use of Millicell cell culture inserts (chambers) containing a permeable membrane with 3-μm pores at the base. The Millicell inserts utilized in this kit are appropriate for cells projecting neurites of up to 3 µm diameter, e.g. N1E-115 cells [Abe et al., 2003], Dorsal Root Ganglia and…

CHEMICON's NS225 Neurite Outgrowth Assay Kit (1 μm) utilizes microporous tissue culture insert technology from EMD Millipore and is based on the use of Millicell cell culture inserts (chambers) containing a permeable membrane with 1 μm pores at the base. With this system, it is possible to screen numerous biological and pharmacological agents simultaneously, directly evaluate adhesion and guidance receptor functions responsibl…

ApopTag® Terminal deoxynucleotidyl Transferase (TdT) is a recombinant enzyme intended for use in labeling the 3'-OH ends of fragmented DNA during apoptotic cell detection. Qualified for use with Apoptag® In Situ Apoptosis Detection Kits

Rat mammary gland undergoes programmed cell death processes during the tissue regression that follows lactation. Apoptotic bodies, which can be seen by routine histologic staining, can be specifically stained by techniques that localize DNA strand breaks in situ. The specificity of staining for strand breaks can thus be correlated with the morphological changes that define the process of apoptosis.

APOPTAG® Plastic Coverslips are designed to be custom fitted to the specific APOPTAG® kit application.

The ApopTag® Peroxidase In Situ Oligo Ligation Kit specifically detects apoptosis by staining only cells that contain double-stranded breaks that are blunt-ended or have a one base 3' overhang (cells containing nicked, gapped, 3'-recessed, 3'-overhanging ends longer than one base and single-stranded ends are not detected). The high analytic specificity of the ApopTag® ISOL Kit minimizes background due to non-specific labeling…
