Precaution of Use: This product contains Sodium azide: a POISONOUS AND HAZARDOUS SUBSTANCE which should be handled by trained staff only.

Storage: -20 °C

Storage Comment: Store vial at -20° C or below prior to opening. This vial contains a relatively low volume of reagent (25 μL). To minimize loss of volume dilute 1:10 by adding 225 μL of the buffer stated above directly to the vial. Recap, mix thoroughly and briefly centrifuge to collect the volume at the bottom of the vial. Use this intermediate dilution when calculating final dilutions as recommended below. Store the vial at -20°C or below after dilution. Avoid cycles of freezing and thawing.

Expiry Date: 12 months

Target Details for Leptin

Target: Leptin (LEP)

Alternative Name: Lep

Background: Background: Leptin is a key player in the regulation of energy balance and body weight control. Obesity associated leptin is the product of the OB gene and has been identified with Type II diabetes. Once released into the circulation, it has central and peripheral effects by binding LEPR, found in many tissues, which results in the activation of several major signaling pathways. It acts as an appetite-regulating factor, regulates bone mass and secretion of hypothalamo-pituitary-adrenal hormones, it increases basal metabolism, influences reproductive function, regulates pancreatic beta-cell function and insulin secretion, it induces FOS and SOCS3 expression to release anorexigenic peptides. It has a modulatory role in nutrient absorption. It reduces glucose absorption by enterocytes by activating PKC and leading to a sequential activation of p38, PI3K and ERK signaling pathways which exerts an inhibitory effect on glucose absorption. It acts as a growth factor on certain tissues, through the activation of different signaling pathways increases expression of genes involved in cell cycle regulation such as CCND1, via JAK2-STAT3 pathway, or VEGFA, via MAPK1/3 and PI3K-AKT1 pathways. It may also play an apoptotic role via JAK2-STAT3 pathway and up-regulation of BIRC5 expression. It plays a pro-inflammatory role, in synergy with IL1B, by inducing NOS2 which promotes the production of IL6, IL8 and Prostaglandin E2, through a signaling pathway that involves JAK2, PI3K, MAP2K1/MEK1 and MAPK14/p38. In adaptive immunity, promotes the switch of memory T-cells towards T helper-1 cell immune responses. Increases CD4+CD25- T cells proliferation and reduces autophagy during TCR (T cell receptor) stimulation, through MTOR signaling pathway activation and BCL2 up-regulation.
