STORAGE:  2-8 C in the dark.

IMPORTANT: Sodium azide forms explosive compounds with heavy metals. These products contain <0.05% (w/w) azide which with repeated contact with lead and copper commonly found in plumbing drains may result in the buildup of shock sensitive compounds. Dispose in accordance with regulations from your institute.

Description:

Leptin (LEP), a hormone that is secreted by white adipocytes, plays a major role in the regulation of body weight. This protein, which acts through the leptin receptor, functions as part of a signaling pathway that can inhibit food intake and/or regulate energy expenditure to maintain constancy of the adipose mass. Leptin also has several endocrine functions, and is involved in the regulation of immune and inflammatory responses, hematopoiesis, angiogenesis and wound healing. Mutations in the gene and/or its regulatory regions cause severe obesity, and morbid obesity with hypogonadism. This gene that encodes Leptin has also been linked to type 2 diabetes mellitus development.
