Human Leptin (LEP) CLIA Kit

Cat. Num. AAA2708608

• Gene Names: LEP; OB; OBS; LEPD
• Reactivity: Human
• Applications: Chemiluminescence Immunoassay (CLIA)
• Synonyms: Leptin (LEP); Human Leptin (LEP) CLIA Kit; Leptin; OB; OBS; Obesity Homolog; Obesity Factor; Obese Protein; LEP clia kit

• Reactivity: Human
• Specificity: This assay has high sensitivity and excellent specificity for detection of Leptin (LEP).; No significant cross-reactivity or interference between Leptin (LEP) and analogues was observed.
• Sequence Length: 167

• Applicable Applications for LEP clia kit: Chemiluminescence Immunoassay (CLIA)
• Assay Type: Double-antibody Sandwich
• Samples: Serum, plasma, saliva, tissue homogenates, cell lysates, cell culture supernates and other biological fluids
• Detection Range: 41.2-30,000pg/mL
• Sensitivity: The minimum detectable dose of this kit is typically less than 14.1pg/mL
• Precision: Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Leptin (LEP) were tested 20 times on one plate, respectively.; Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Leptin (LEP) were tested on 3 different plates, 8 replicates in each plate.; CV(%) = SD/meanX100; Intra-Assay: CV<10%; Inter-Assay: CV<12%
• Test Principle: The microplate provided in this kit has been pre-coated with an antibody specific to Leptin (LEP). Standards or samples are then added to the appropriate microplate wells with a biotin-conjugated antibody specific to Leptin (LEP). Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. Then the mixture of substrate A and B is added to generate glow light emission kinetics. Upon plate development, the intensity of the emitted light is proportional to the Leptin (LEP) level in the sample or standard.
• Preparation and Storage: The stability of kit is determined by the loss rate of activity. The loss rate of this kit is less than 5% within the expiration date under appropriate storage condition.; To minimize extra influence on the performance, operation procedures and lab conditions, especially room temperature, air humidity, incubator temperature should be strictly controlled. It is also strongly suggested that the whole assay is performed by the same operator from the beginning to the end.

NCBI Description

This gene encodes a protein that is secreted by white adipocytes into the circulation and plays a major role in the regulation of energy homeostasis. Circulating leptin binds to the leptin receptor in the brain, which activates downstream signaling pathways that inhibit feeding and promote energy expenditure. This protein also has several endocrine functions, and is involved in the regulation of immune and inflammatory responses, hematopoiesis, angiogenesis, reproduction, bone formation and wound healing. Mutations in this gene and its regulatory regions cause severe obesity and morbid obesity with hypogonadism in human patients. A mutation in this gene has also been linked to type 2 diabetes mellitus development. [provided by RefSeq, Aug 2017]

Uniprot Description

leptin: May function as part of a signaling pathway that acts to regulate the size of the body fat depot. An increase in the level of LEP may act directly or indirectly on the CNS to inhibit food intake and/or regulate energy expenditure as part of a homeostatic mechanism to maintain constancy of the adipose mass. Defects in LEP may be a cause of obesity (OBESITY). It is a condition characterized by an increase of body weight beyond the limitation of skeletal and physical requirements, as the result of excessive accumulation of body fat. Belongs to the leptin family.
