The proglucagon gene is expressed in both pancreatic A cell and intestinal L cell. Tissue-specific posttranslational processing of proglucagon by the prohormone convertase produced the different proglucagon derived peptides (PGDPs) in both pancreas and intestine. The most notable pancreatic PGDP is glucagon, whereas the L cell produces several structurally related peptides, including glucagon-like peptide(GLP)-1 and GLP-2, as well as glicentin and oxyntomodulin, which contain glucagon sequence in their molecules. Among PGDPs, GLP-2 has recently been found to show intestinal epithelial proliferation.

Rat GLP-2 ELISA Assay
Mouse GIP Active ELISA Assay Kit
This Eagle Biosciences Mouse GLP-2 ELISA Assay Kit for determination of mouse GLP-2 in serum or plasma samples is based on a competitive enzyme immunoassay using combination of highly specific antibody to rat GLP-2 (strong cross reactivity to mouse GLP-2) and biotin-avidin affinity system. The 96-wells plate is coated with goat anti rabbit IgG antibody. Mouse GLP-2 standard or samples, labeled antigen and anti-rat GLP-2 polyclonal antibody are added to the wells for competitive immunoreaction. After incubation and plate washing, HRP labeled streptoavidin (SA-HRP) are added to form HRP labeled streptoavidin-biotinylated rat GLP-2- antibody complex on the surface of the wells. Finally, HRP enzyme activity is determined by o-Phenylenediamine dihydrochloride (OPD) and the concentration of mouse GLP-2 is calculated.
- Bring all the reagents and samples to room temperature before beginning the test.
- Fill 75uL of labeled antigen solution into the wells first, then introduce 25uL of each of standard solutions (0, 0.412, 1.235, 3.704, 11.11, 33,33, 100 ng/mL) or samples and finally add 50uL of GLP-2 antibody into the wells.
- Cover the plate with adhesive foil and incubate it at 4ºC for 16 ~ 18 hours.(Still, shaker not need)
- Take off the adhesive foil, aspirate the solution in the wells and wash the wells three times with approximately 0.35 mL/well of washing solution.
- Pipette 100uL of SA-HRP solution into the wells.
- Cover the plate with adhesive foil and incubate it at room temperature (20-30ºC) for 1 hour. During the incubation, the plate should be shake with a plate shaker.
- Resolve OPD tablet with 12 mL of substrate buffer. It should be prepared immediately before use.
- Take off the adhesive foil, aspirate and wash the wells five times with approximately 0.3 mL/well of washing solution.
- Add 100uL of substrate solution into the wells, cover the plate with adhesive foil and incubate it for 30 minutes at room temperature.
- Add 100uL of stopping solution into the wells to stop reaction.
- Read the optical absorbance of the wells at 492nm. Calculate mean absorbance values of wells containing standards and plot a standard curve on semilogarithmic graph paper (abscissa: concentration of standard; ordinate: absorbance values). Use the standard curve to read mouse GLP-2 concentrations in samples from the corresponding absorbance values.
