Fatty Acid Binding Protein, Liver (FABP)

Cat no: F0019-76P1

Fatty Acid Binding Protein, Liver (FABP)

The L-FABP protein is derived from the human FABP1 gene. FABPs are small intracellular proteins (~13-14kD) with a high degree of tissue specificity that bind long chain fatty \nacids. They are abundantly present in various cell types and play an important role in the intracellular utilization of fatty acids, transport and metabolism. There are at least nine distinct types of FABP, each showing a specific pattern of tissue expression. Due to its small size, FABP leaks rapidly out of \nischemically damaged necrotic cells leading to a rise in serum levels. Ischemically damaged tissues are characterized histologically by absence (or low presence) of FABP facilitating recognition of such areas. L-FABP is localized in hepatocytes and brush cells found in the biliary tract, in mucosa of small \nand large intestine and in intestinal metaplasia of the gastric mucosa. Furthermore, L-FABP is present in the epithelium of the proximal tubule of the kidney. \n\nApplications:\nSuitable for use in Western Blot, Immunoprecipitation, Immunofluorescence and Immunohistochemistry. Other applications have not been tested. \n\nRecommended Dilutions:\nWestern Blot: 1:50\nImmunohistochemistry (Frozen, paraffin): 1:50\nOptimal dilutions to be determined by the researcher.\n\nStorage and Stability:\nMay be stored at 4 degrees C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20 degrees C. Aliquots are stable for 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
