Background Connective tissue consists of a ground of glycosaminoglycans, proteoglycans and glycoproteins through which various fibres run. These fibres can be collagenous, elastic or reticular. Reticular fibres are composed from the family of collagen proteins and give tensile strength. These fibres are made by reticular fibroblasts. 
Fibroblasts are the least specialized cells in the connective-tissue family. They are dispersed in connective tissue throughout the body, where they secrete a nonrigid extracellular matrix (ECM) that is rich in type I and/or type III collagen. Conective tissue consists of glycosaminoglycans, proteoglycans and glycoproteins through which various fibres run. These fibres can be collagenous, elastic or reticular. Reticular fibres are composed from the family of collagen proteins and give tensile strength. These fibres are made by reticular fibroblasts. The activation of fibroblasts by inflammatory stimuli results in their migration, proliferation and deposition of extracellular matrix components, important features involved in both wound healing and fibrosis.

Storage Store lyophilized at 2-8°C for 6 months or at -20°C long term.
After reconstitution store the antibody undiluted at 2-8°C for one month 
or (in aliquots) at -20°C long term.
Avoid repeated freezing and thawing.
Shelf life: one year from despatch.
Affinity Chromatography
Buffer System:
Stock solution contains PBS, pH 7.2 with 5 mg/ml BSA as a stabilizer and 0.09% Sodium Azide as preservative
Lyophilized purified IgG fraction
Restore with 0.5 ml distilled water.
Species Reactivity
Species reactivity (tested):
Mouse (Reticular Fibroblasts, Reticular Fibres), Pig and Human.
Reacts with Mouse reticular fibroblasts, reticular fibres and Human tonsil.
ER-TR7 detects an antigen present in and produced by reticular fibroblasts. The recognized antigen is most likely distinct from Laminin, Fibronectin, Collagen types I-IV, Heparan Sulfate Proteoglycan, Entactin, and Nidogen.
The antibody is useful to stain the microanatomy of various organs, in particular the connective tissue framework in lymphoid organs. The antibody also stains subendothelial deposits in the plaque area of atherosclerotic plaques.
Antigen Distribution
Isolated Cells: The antigen is found in the cytoplasm of fibroblast cell lines.
Tissue Sections: The antigen is expressed in connective tissues which form a supporting network between parenchymal cells of all organs tested so far (see table below). Thus, the supportive mesenchymal structures of larger vessels can be studied. In spleen, a very clear delineation of red and white pulp is obtained. Capsule, sinuses, follicules, paracortex and medullary cords are also clearly delineated in lymph nodes.
