應用

Ochratoxin A has been used as a mycotoxin:
  • to test its effect on metabolism and hypoxia in human embryonic kidney (HEK293) cells
  • to test its cytotoxic effects in bovine mammary epithelial cells
  • as a standard for gamma radiation studies with food products and in cytotoxic studies using Hep G2 cells

生化／生理作用

Ochratoxin A (OTA), a renal toxin, is produced majorly by Aspergillus and Penicillium fungal species. It is immunotoxic, teratogenic myelotoxic, and mutagenic. It effectively interrupts the intestinal barrier functions. OTA displays a long elimination half-life and stimulates the major inflammatory cytokines release.
Ochratoxin A is a mycotoxin found in food that is nephrotoxic and carcinogenic in the kidney and induces differentiation in cloned renal cell lines. Increases endoplasmic reticulum ATP-dependent Ca2+ pump activity.

準備報告

This product is also soluble in chloroform (9.80 - 10.20 mg/ml), methanol (10 mg/ml), ethanol (50 mM), and DMSO (100 mM).
