Mouse GDN (Glia Derived Nexin) ELISA Kit

The Mouse GDN (Glia-derived Nexin) ELISA Kit is specifically designed for the precise measurement of GDN levels in mouse serum, plasma, and cell culture supernatants. This kit offers exceptional sensitivity and specificity, guaranteeing accurate and consistent results for various research purposes.GDN, also known as Serpin E2, is a key protein that regulates multiple biological processes, including inflammation, immune response, and tissue repair.

Its dysregulation has been linked to various diseases, such as Alzheimer's disease, inflammatory conditions, and cancer, making it a valuable biomarker for investigating these pathologies and potential therapeutic interventions.With the Mouse GDN ELISA Kit, researchers can gain valuable insights into the role of GDN in health and disease, paving the way for innovative discoveries and advancements in biomedical research.

Assay type:Sandwich
Format:96T
Assay time:4.5h
Reactivity:Mouse
Detection Method:Colormetric
Detection Range:6.25-400 pg/mL
Sensitivity:3.75 pg/mL
Sample Volume Required Per Well:100µL
Sample Type:Serum, plasma and other biological fluids
Specificity:This kit recognizes Mouse GDN in samples. No significant cross-reactivity or interference between Mouse GDN and analogues was observed.

This ELISA kit uses Sandwich-ELISA as the method. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Mouse GDN. Standards or samples are added to the appropriate micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Mouse GDN and Avidin-Horseradish Peroxidase (HRP) conjugate are added to each micro plate well successively and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain Mouse GDN, biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by adding Stop Solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The OD value is proportional to the concentration of Mouse GDN. The concentration of Mouse GDN in samples can be calculated by comparing the OD of the samples to the standard curve.

As the OD values of the standard curve may vary according to the conditions of the actual assay performance (e. g. operator, pipetting technique, washing technique or temperature effects), the operator should establish a standard curve for each test. Typical standard curve and data is provided below for reference only.

  1. Set standard, test sample and control (zero) wells on the pre-coated plate and record theirpositions. It is recommended to measure each standard and sample in duplicate. Note: addall solutions to the bottom of the plate wells while avoiding contact with the well walls. Ensuresolutions do not foam when adding to the wells.
  2. Aliquot 100µl of standard solutions into the standard wells.
  3. Add 100µl of Sample / Standard dilution buffer into the control (zero) well.
  4. Add 100µl of properly diluted sample (serum, plasma, tissue homogenates and otherbiological fluids) into test sample wells.
  5. Cover the plate with the sealer provided in the kit and incubate for 90 min at 37°C.
  6. Aspirate the liquid from each well, do not wash. Immediately add 100µL of BiotinylatedDetection Ab working solution to each well. Cover the plate with a plate seal and gently mix. Incubate for 1 hour at 37°C.
  7. Aspirate or decant the solution from the plate and add 350µL of wash buffer to each welland incubate for 1-2 minutes at room temperature. Aspirate the solution from each well andclap the plate on absorbent filter paper to dry. Repeat this process 3 times. Note: a microplatewasher can be used in this step and other wash steps.
  8. Add 100µL of HRP Conjugate working solution to each well. Cover with a plate seal andincubate for 30 min at 37°C.
  9. Aspirate or decant the solution from each well. Repeat the wash process for five times asconducted in step 7.
  10. Add 90µL of Substrate Reagent to each well. Cover with a new plate seal and incubate forapproximately 15 min at 37°C. Protect the plate from light. Note: the reaction time can beshortened or extended according to the actual color change, but not by more than 30min.
  11. Add 50 µL of Stop Solution to each well. Note: Adding the stop solution should be done inthe same order as the substrate solution.
  12. Determine the optical density (OD value) of each well immediately with a microplate readerset at 450 nm.
