  • Product overview

    Abcam’s Human Insulin ELISA (Enzyme-Linked Immunosorbent Assay) kit is an in vitro enzyme-linked immunosorbent assay for the quantitative measurement of Human Insulin and Proinsulin in serum, plasma, cell culture supernatants.

    This assay employs an antibody specific for Human Insulin coated on a 96-well plate. Standards and samples are pipetted into the wells and Insulin present in a sample is bound to the wells by the immobilized antibody. The wells are washed and biotinylated anti-Human Insulin antibody is added. After washing away unbound biotinylated antibody, HRP-conjugated streptavidin is pipetted to the wells. The wells are again washed, a TMB substrate solution is added to the wells and color develops in proportion to the amount of Insulin bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.

    This kit detects both insulin and proinsulin.

  • Research areas
  • Function
    Insulin decreases blood glucose concentration. It increases cell permeability to monosaccharides, amino acids and fatty acids. It accelerates glycolysis, the pentose phosphate cycle, and glycogen synthesis in liver.
  • Involvement in disease
    Defects in INS are the cause of familial hyperproinsulinemia (FHPRI) [MIM:176730].
    Defects in INS are a cause of diabetes mellitus insulin-dependent type 2 (IDDM2) [MIM:125852]. IDDM2 is a multifactorial disorder of glucose homeostasis that is characterized by susceptibility to ketoacidosis in the absence of insulin therapy. Clinical fetaures are polydipsia, polyphagia and polyuria which result from hyperglycemia-induced osmotic diuresis and secondary thirst. These derangements result in long-term complications that affect the eyes, kidneys, nerves, and blood vessels.
    Defects in INS are a cause of diabetes mellitus permanent neonatal (PNDM) [MIM:606176]. PNDM is a rare form of diabetes distinct from childhood-onset autoimmune diabetes mellitus type 1. It is characterized by insulin-requiring hyperglycemia that is diagnosed within the first months of life. Permanent neonatal diabetes requires lifelong therapy.
    Defects in INS are a cause of maturity-onset diabetes of the young type 10 (MODY10) [MIM:613370]. MODY10 is a form of diabetes that is characterized by an autosomal dominant mode of inheritance, onset in childhood or early adulthood (usually before 25 years of age), a primary defect in insulin secretion and frequent insulin-independence at the beginning of the disease.

Application to plasma samples from pigs

Good Excellent 5/5 (Ease of Use)
Plasma samples from pigs 3-4 months old (25-30 kg body weight) were obtained after overnight fasting.

Assay procedure was performed according to manufacturer instructions. However, standard curve (duplicates) was modified due to the low concentrations observed in fasted pigs. Standard concentrations were 100, 50, 25, 12.5, 6.25, 3.125 and 1.5625 microIU/mL, prepared by a 1:3 dilution of the first standard provided with the product, and consecutive 1:2 dilutions thereafter.

Plasma samples were added to each well by duplicate (100 microL) as suggested by the manufacturer instructions, with no dilution. All remaining steps were performed in accordance with manufacturer instrucitions, with no modificatons. Readings were performed at 450 nm.

Results were as follows:
Control animals: 6.63, 3.65, 1.10 and 4.67 microIU/mL (mean: 4.01±1.15 microIU/mL)
Treatment A: 54.95, 9.29, 8.77, 5.10 microIU/mL (mean: 19.53±11.84).

We do not have data for camel samples tested with the human insulin ELISA, ab100578. However, insulin is well-conserved between the two species, so it is possible the ELISA will detect camel insulin.

To check the similarity between the two spe...
