Rat Fibronectin ELISA Kit PicoKine®

• Background:

  Fibronectin (FN) also known as LETS, is identified on the surfFN of fibroblasts by labeling with radioactive compounds or specific antibodies. Fibronectin is a 430,000-dalton dimeric glycoprotein that exists in 2 forms, termed cellular and plasma fibronectin. Cellular and plasma fibronectins are heterodimers consisting of similar but not identical polypeptides. These two forms of FN differ in biologic activity. Fibronectins bind cell surfFNs and various compounds including collagen, fibrin, heparin, DNA, and actin. Because fibronectin stimulates endocytosis in several systems and promotes the clearance of particulate material from the circulation, it could function in the clearance of C1q-coated material such as immune complexes or cellular debris. Fibronectins are involved in cell adhesion, cell motility, opsonization, would healing, and maintenance of cell shape. LETS, encoded on chromosome 8, is responsible for the LETS protein expression in humans. Because LETS has been implicated in tumorigenicity and cellular transformation, it is of interest that rearrangement or modifications in the number of chromosome 8 have been associated with certain forms of cancer. The standard used in this kit is isolated from rat plasma with the molecular mass of 200-250KDa.

• Description:

  Fibronectin ELISA Kit

• Synonyms:

  Fibronectin; FN; Anastellin; Fn1

• Gene Name:

  Fibronectin

• UniProt:

  P04937

• Reactivity:

  Rat

• Cross Reactivity:

  There is no detectable cross-reactivity with other relevant proteins.

• Immunogen:

  Target protein isolated from rat plasma

• Tissue Specificity:

  Plasma FN (soluble dimeric form) is secreted by hepatocytes. Cellular FN (dimeric or cross-linked multimeric forms), made by fibroblasts, epithelial and other cell types, is deposited as fibrils in the extracellular matrix.

• Applications:

  ELISA

• Sample Type:

  Cell culture supernatants, serum and plasma (heparin, EDTA, citrate) .

• Detection Range:

  156 pg/ml - 10,000 pg/ml

• Sensitivity:

  <15 pg/ml

• Function:

  Fibronectins bind cell surfaces and various compounds including collagen, fibrin, heparin, DNA, and actin. Fibronectins are involved in cell adhesion, cell motility, opsonization, wound healing, and maintenance of cell shape. Involved in osteoblast compaction through the fibronectin fibrillogenesis cell-mediated matrix assembly process, essential for osteoblast mineralization. Participates in the regulation of type I collagen deposition by osteoblasts (By similarity) . .
