Glucagon-Like Peptide-1 (GLP-1) Active ELISA Kit

  • Created on the 9 February, 2017.

BACKGROUND

Glucagon-like peptide-1 (GLP-1) is a neuropeptide that has an important role in regulating glucose homeostasis and is secreted in response to food intake. It belongs to the incretins family of gastrointestinal hormones that have the ability to increase the levels of insulin that is released from the beta cells of the islets of Langerhans after food intake. GLP-1  also  is able to inhibit  glucagon  release  from  the  alpha  cells  of  the  islets  of Langerhans. This causes a reduction in the rate of nutrients into the blood stream as a result of slowing gastric emptying, it is thought this may be directly leading to a reduction in food intake.

One of the major source for GLP-1 in the periphery is the intestinal L cell that that have the ability to secrete GLP-1 as a gut hormone, on the other hand the major source in the brain is the nucleus of the solitary tract and this is known to be a source of a widely distributed set of GLP-1 projection neurons. There are multiple forms of GLP-1 that exist and the biologically active forms include GLP-1-(7-37) and GLP-1-(7-36) NH2. These can be formed as a result of selective cleavage of the pro-glucagon molecule.

There a number of methods which are used to measure active GLP-1 peptide, ELISA assays are usually the preferred choice due to their sensitivities they can offer. This ELISA kit is designed to measure active forms of GLP-1 which includes GLP-1 (7-36) amide and GLP-1 (7-37).

INTENDED USE

Human GLP-1 active ELISA kit is a reliable quantitative procedure for measuring glucagon-like peptide-1 (GLP-1 [GLP-1 (7-36) amide and GLP-1 (7-37)]) specifically in human EDTA plasma. This assay has a minimum sensitivity detection limit of 0.1 pmol/l.

SENSITIVITY

The minimum sensitivity detection limit of glucagon-like peptide-1 (GLP-1 [GLP-1 (7-36) amide and GLP-1 (7-37)]) using this GLP-1 active ELISA kit was approximately 0.1 pmol/l. The dynamic assay range for this kit is 1.25 – 80.0 pmol/l.

TESTIMONIALS arrow icon

Your secretory IgA ELISA kit gave good results and I was also really impressed with how quickly we received it.

L. Johnston

It is refreshing to know that you have a technical team that is very knowledgeable. I have already recommended your company to other researchers in our department.

Dr. P. Anderson
Lecturer / University College London (UCL)

I am a first time user and found that your instruction manual was very easy to follow. The insulin ELISA kit performed well and I was happy with the results that were generated.

J. Thomas
Senior Technician / Addenbrooke’s Hospital

I carried out a pilot study comparing the performance of many ELISA kits from different suppliers and found your kits to be one of the better performers. We observed good linearity and tight replicates.
