This assay has high sensitivity and excellent specificity for detecting Mouse UCP1 (Uncoupling Protein 1 Mitochondrial). The assay range is from 0.156 to 10 ng/ml (Sandwich kit) with a sensitivity of 0.062 ng/ml. There is no detectable cross to reactivity with other relevant proteins. Activity loss rate and accelerated stability test ect have been conducted to guarantee the best performance of the products after long storage and delivery.

• High sensitivity and specificity
• Perfect reproducibility and consistency across batches
• Quality control with three-level inspections
• Wide range of targets/species available
• Intra-Assay: CV <10%, Inter-Assay: CV <12%

UCP1 is activated in the brown fat cell by fatty acids and inhibited by nucleotides. Sympathetic nervous system terminals release Norepinephrine onto a Beta-3 adrenergic receptor on the plasma membrane. This activates adenylyl cyclase, which catalyses the conversion of ATP to cyclic AMP. cAMP activates protein kinase A, causing its active C subunits to be freed from its regulatory R subunits. Active protein kinase A, in turn, phosphorylates triacylglycerol lipase, thereby activating it. The lipase converts triacylglycerols into free fatty acids, which activate UCP1, overriding the inhibition caused by purine nucleodides. At the termination of thermogenesis, the mitochondria oxidize away the residual fatty acids, UCP1 inactivates and the cell resumes its normal energy-conserving mode.
