Background: IL-36 alpha/IL-1F6

Interleukin 36 alpha (IL-36 alpha), also known as IL-1F6 and FIL1 epsilon, is a member of the IL-1 family of proteins. Cells reported to express IL-36 alpha include monocytes, B cells, and T cells. Notably, IL-36 alpha is the only novel IL-1 family member expressed on T-cells. The receptor for IL-36 alpha is reported to be a combination of IL-1 R6/IL-1 R rp2 and IL-1 R3/IL-1 R AcP. Recombinant IL-36 alpha has been shown to activate pathways involving NF-kappa B and MAPK in an IL-1 R6/IL-1 R rp2-dependent manner.

Assay Procedure


Plate Preparation

  1. Dilute the Capture Antibody to the working concentration in PBS without carrier protein. Immediately coat a 96-well microplate with 100 μL per well of the diluted Capture Antibody. Seal the plate and incubate overnight at room temperature.
  2. Aspirate each well and wash with Wash Buffer, repeating the process two times for a total of three washes. Wash by filling each well with Wash Buffer (400 μL) using a squirt bottle, manifold dispenser, or autowasher. Complete removal of liquid at each step is essential for good performance. After the last wash, remove any remaining Wash Buffer by aspirating or by inverting the plate and blotting it against clean paper towels.
  3. Block plates by adding 300 μL of Block Buffer to each well. Incubate at room temperature for a minimum of 1 hour.
  4. Repeat the aspiration/wash as in step 2. The plates are now ready for sample addition.

Assay Procedure

  1. Add 100 μL of sample or standards in Reagent Diluent, or an appropriate diluent, per well. Cover with an adhesive strip and incubate 2 hours at room temperature.
  2. Repeat the aspiration/wash as in step 2 of Plate Preparation.
  3. Add 100 μL of the Detection Antibody, diluted in Reagent Diluent, to each well. Cover with a new adhesive strip and incubate 2 hours at room temperature.
  4. Repeat the aspiration/wash as in step 2 of Plate Preparation.
  5. Add 100 μL of the working dilution of Streptavidin-HRP to each well. Cover the plate and incubate for 20 minutes at room temperature. Avoid placing the plate in direct light.
  6. Repeat the aspiration/wash as in step 2.
  7. Add 100 μL of Substrate Solution to each well. Incubate for 20 minutes at room temperature. Avoid placing the plate in direct light.
  8. Add 50 μL of Stop Solution to each well. Gently tap the plate to ensure thorough mixing.
  9. Determine the optical density of each well immediately, using a microplate reader set to 450 nm. If wavelength correction is available, set to 540 nm or 570 nm. If wavelength correction is not available, subtract readings at 540 nm or 570 nm from the readings at 450 nm. This subtraction will correct for optical imperfections in the plate. Readings made directly at 450 nm without correction may be higher and less accurate.

  1. How soon after reconstitution should standards in the Human IL-36 alpha/IL-1F6 DuoSet ELISA Kit, Catalog # DY1078-05, be used, or aliquotted and stored?

    • Standards in this kit are very sensitive and should not be allowed to sit longer than about 15-20 minutes before they are aliquotted and stored, undiluted, at -80C. Standards left at room temperature for longer periods could lead to a significant drop in standard signal on subsequent use. Standards should be used soon after reconstitution or after a new aliquot is thawed.

Human IL-36 alpha/IL-1F6 DuoSet ELISA
By Anonymous on 04/02/2020
Sample Tested: Serum and Plasma

We used this kit for the quantification of IL-36 alpha in human serum and plasma. Unfortunately, we could not find any IL-36 in our samples. Nevertheless, the standard curve works very well.
