Leptin Protein (LEP)

Catalog No. ABIN2724655

Product Details

Target: Leptin (LEP)

Protein Type: Recombinant

Biological Activity: Active

Origin: Human

Source: Escherichia coli (E. coli)

Application: Functional Studies (Func), Antibody Production (AbP), Standard (STD), Protein Interaction (PI)

Specificity: Optimal preservation of protein structure, post-translational modifications and functions.

Characteristics:

• Recombinant human Leptin protein expressed in E. coli.
• Produced with end-sequenced ORF clone
• Tested for bioactivity.

Purity: > 95 % as determined by SDS-PAGE and Coomassie blue staining

Endotoxin Level: Endotoxin level is <0.1 ng/μg of protein (<1EU/μg).

Biological Activity Comment: PeproTech's human Leptin is biologically active in the ob/ob mouse obesity model. The ob/ob mice were treated via intraperitoneal injection once daily at a dose of 5 ug Leptin/gm of body weight for 7 days. Significant effects on body weight, food consumption, and plasma glucose levels were observed to saline-treated controls.

Background: This gene encodes a protein that is secreted by white adipocytes, and which 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. This protein also has several endocrine functions, and is involved in the regulation of immune and inflammatory responses, hematopoiesis, angiogenesis and wound healing. Mutations in this gene and/or its regulatory regions cause severe obesity, and morbid obesity with hypogonadism. This gene has also been linked to type 2 diabetes mellitus development.
