Provitro - Morphological Structure Tissue
The morphological structure of tissue can be depicted with high accuracy by means of histological sections. Staining results depend on numerous factors, including pH of the buffer solution, staining time and method of fixation. Haematoxylin, for example, is used to stain cell and tissue structures, such as cell nuclei, mitochondria, myelin, elastin and collagen fibres. Additional information may be obtained from counterstaining (differential staining), ...

Tissue Microarrays (TMA)
Tissue microarrays are an ideal tool in high-throughput analysis for antigen distribution or validation of newly identified pathogenetic genes. Tissue microarrays with up to 100 individual tissue samples on a single slide minimise variations in staining intensity, yielding consistent results. Tissue spots with a diameter of up to 2 mm provide sufficient area for morphological evaluation. Tissue microarrays provide a rapid solution for localisation of DNA or protein molecules in normal and pathological human tissues.

Provitro - Inflammatory + Autoimmune Tissue Microarrays (TMA)
Cultures based on cell monolayers have the advantage of reducing tissue complexity to a minimum. However, the lack of normal physiological cell-matrix interactions leads the cell metabolism and gene expression towards a dedifferentiated state. Compared to a monolayer, three-dimensional cultures are associated with a higher cell density, and nutrient supply depends on diffusion through the extracellular matrix. This requires more exacting ...

Provitro - Model iConTMA - Tissue
iConTMA are tissue slides for internal control of immunohistochemistry or in situ hybridisation. The slides contain specific positive and negative tissue spots providing enough space to add your tissue under investigation. The specificity of the reaction can be determined and the reactivity can be scored by comparing your sample with the iConTMA® ...

Primary Cell Cultures
Each unit (vital = proliferating flask, or cryo = cryopreserved) contains more than 500,000 cells. Each cell strain is performance tested by extensive growth assays and inspection of cell morphology. Provitro guarantees a minimum of 10 population doublings for most normal human cell cultures. Cells test negative for HIV-1 DNA, hepatitis B DNA, hepatitis C DNA, mycoplasma, bacteria, yeast and fungi. Provitro guarantees the homogeneity of each cell type according to celltype-specific test markers. Each unit comes with a certificate specifying the results of quality control for this cell culture.

Provitro - Human Endothelial Cells
Endothelium is the cover term for the blood-oriented cells in the innermost layer of the vascular wall (intima). Functioning as physiological barrier to tissue, the CD 31- and vWF-positive cells express nitrogen oxide (NO) which plays a role in regulating the tonus of the vascular musculature. Damage to the endothelial cell layer has been assumed to be possibly a causative factor in the development of arteriosclerosis. Endothelium plays an equally ...
