Measurement of immunofunctional leptin to detect and monitor patients with functional leptin deficiency.European Journal of Endocrinology. 173:3, 315-322. DOI: 10.1530/EJE-16-0821.

The authors from German research centers Ulm, Leipzig and Tübingen, as well as scientists at Mediagnost report a new assay that measures Leptin binding capability to the leptin receptor. It therefore identifies individuals with bioinactive leptin due to mutations affecting receptor binding. It is thus an improvement over total immunoreactive leptin measurements to identify those with functional leptin insufficiency.

Highlight from Publication:

“The new Mediagnost bioLep assay L07 is able to detect impaired leptin bioactivity in severely obese patients with a homozygous gene defect as well as in heterozygous carriers of such mutations and is a time- and cost-effective diagnostic tool to identify these individuals and ultimately allow proper therapy to be initiated where applicable as early in life as possible.”

Functional Leptin ELISA

Functional Leptin ELISAis part our Endocrine Assay Kit Line, a line that offers a comprehensive product grouping of unique and for measuring a variety of analytes related to diabetes and obesity research.

This assay is:

  • Based on immobilized soluble leptin receptor and a highly specific polyclonal antibody: allowing researchers to measure biologically active / receptor binding leptin only
  • Sensitive, specific, and provides results within 4 hours

 

EagleBio's Histamine ELISA

Histamine ELISA is for Research Use Only.

EagleBio’s Histamine ELISA was recently utilized in a study byBrigham and Women’s Hospital and Harvard Medical School. Histamine ELISA  a kit designed for the quantitative determination of histamine in plasma, urine, and cell culture. This assay is part of our Immunology Assay Kit line which is comprised of a unique,versatile set of products for a variety of applications, research, and fields of study.

Leptin Deficiency Shifts Mast Cells toward Anti-Inflammatory Actions and Protects Mice from Obesity and Diabetes by Polarizing M2 Macrophages 

Mast cells (MCs) contribute to the pathogenesis of obesity and diabetes. This study demonstrates that leptin deficiency slants MCs toward anti-inflammatory functions. MCs in the white adipose tissue (WAT) of lean humans and mice express negligible leptin.
