Description_x000D_ General description_x000D_ Uncoupling protein (UCP1) is a 32 kDa, mitochondrial inner membrane protein. It is active as a proton channel forming dimer. It can bind purine nucleotides and is capable of being stimulated by fatty acids._x000D_ Specificity_x000D_ Anti-UCP-1 specifically recognizes human, mouse and rat UCP-1. Staining of the UCP-1 band is specifically inhibited with the immunizing peptide. The epitopes recognized are compatible with routine formalin-fixation and paraffin-embedding._x000D_ Immunogen_x000D_ synthetic peptide corresponding to human UCP1 sequence (amino acids 145-159) with N-terminal cysteine added, conjugated to KLH. The corresponding sequence is identical in rat and mouse UCP1._x000D_ Application_x000D_ Anti-UCP-1 antibody produced in rabbit has been used in western blotting and immunohistochemistry._x000D_ Physical form_x000D_ Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 1% bovine serum albumin and 15 mM sodium azide._x000D_ Disclaimer_x000D_ Unless otherwise stated in our catalog or other company documentation accompanying the product(s), our products are intended for research use only and are not to be used for any other purpose, which includes but is not limited to, unauthorized commercial uses, in vitro diagnostic uses, ex vivo or in vivo therapeutic uses or any type of consumption or application to humans or animals._x000D_ Biochem/physiol Actions_x000D_ Uncoupling proteins (UCPs) are transporters functioning as enzymatic uncouplers of oxidative phosphorylation. They can return protons pumped by the respiratory chain to the mitochondrial matrix. UCP-1 is exclusively expressed in brown adipose tissue (BAT) in rodents and in neonates where it is regulated by norepinephrine and thyroid hormones. UCP-1 has been shown to depend on CoQ (ubiquinone) as an obligatory co-factor.
