This protein is a receptor for leptin (an adipocyte-specific hormone that regulates body weight), and is involved in the regulation of fat metabolism, as well as in a novel hematopoietic pathway that is required for normal lymphopoiesis. Leptin Receptor\/CD295 is a transmembrane catalytic receptors found on NPY\/AgRP and alpha-MSH\/CART neurons in hypothalamic nuclei. Leptin receptors (Ob-Rs) are coded for by one human gene that produces six different isoforms; Ob-Ra - Ob-Rf. Ob-Rs exist as constitutive dimers at physiological expression levels. Only the Ob-Rb isoform can transduce intracellular signals and does so through activation of the JAK2\/STAT3, PI 3-K and MAPK signaling cascades. Activation of Ob-Rs mediates transcriptional regulation of the hypothalamic melanocortin pathway and downregulates endocannabinoid expression. Leptin acts via leptin receptors. Leptin resistance has been proposed as a pathophysiological mechanism of obesity. In obese individuals, Ob-Ra (which is involved in active transport of leptin across the blood-brain barrier) expression is downregulated and the individual may be unresponsive to leptin signals. Ob-R antagonists are of great interest in the development of pharmacological treatments for obesity. Mutations in Leptin Receptor\/CD295 have been associated with obesity and pituitary dysfunction.\u003c\/p\u003e\n\n\u003cp\u003eActivity: Immobilized human Leptin at 5 μg\/ml (100 μl\/well) can bind human Leptin receptor with a linear range of 0.032-4.0 μg\/ml.\u003c\/p\u003e\n\n\u003cp\u003eSequence: Met 1-Asp 839\u003c\/p\u003e\n\n\u003cp\u003ePurity: \u0026gt; 95 % as determined by reducing SDS-PAGE.\u003c\/p\u003e\n\n\u003cp\u003eFormulation: Lyophilized from sterile PBS, pH 7.4\u003cbr\u003e\nNormally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.\u003cbr\u003e\nPlease refer to the specific buffer information in the printed manual.\u003c\/p\u003e\n\n\u003cp\u003eReconstitution: Please refer to the printed manual for detailed information.\u003c\/p\u003e\n\n\u003cp\u003eEndotoxin: \u0026lt; 1.0 EU per μg of the protein as determined by the LAL method.\u003c\/p\u003e\n\n\u003cp\u003eCalculated MW: 95 kDa\u003c\/p\u003e\n\n\u003cp\u003eObserved MW: 130-140 kDa\u003c\/p\u003e\n\n\u003cp\u003eStorage: Generally, lyophilized proteins are stable for up to 12 months when stored at -20 to -80℃.
