Resistin ELISA Kit

  • Created on the 12 February, 2017.

BACKGROUND

Resistin is a cysteine-rich protein that is 11.3 kDa and belongs to the protein family of resistin-like molecules (RELM) which also includes: RELMa, RELMb and RELMg. It was first identified in mice, in humans no other RELM family are found apart from resistin and RELMb. There is a 53% homology between the human and murine protein, both containing 11 cysteine-residues, synthesized as a propetide of 108 amino acids that is secreted as a dimer which is linked together by a disulfide bridge of cysteine residues. The structure of resistin is highly dependent on its concentration, there is evidence to suggest there is a concentration dependent shift from a-helical to b-sheet structure.

Resistin expression has be identified in white adipose tissue, pancreatic islets and pituitary of mice. In rats it can also be found in brown adipose tissues, whereas in humans the expression in adipocytes can only be detected at very low levels. However, the human resistin gene can also be expressed in bone marrow, pre-adipocytes marcophages and pancreatic islets. Resistin is an adipose derived hormone that is postulated to link adiposity to insulin resistance. Furthermore, type 2 diabetes has been characterized by a specific target-tissue resistance to insulin which is strongly associated to obesity and the epidemic is most commonly found in industrialised societies. The standard that is used in this assay has a molecular mass between 51-53KDa and it has the ability to detect human resistin including the active enzyme and zymogen.

INTENDED USE

Human resistin ELISA kit is a reliable quantitative procedure for measuring resistin in human serum, plasma, saliva, breast milk, cell culture medium and urine. This assay has a minimum sensitivity detection limit of 6.0 pg/ml.

SENSITIVITY

The minimum sensitivity detection limit of resistin using this human resistin ELISA kit was approximately 6.0 pg/ml. The dynamic assay range for this kit is 0.02 – 1.0 ng/ml.

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.
