Sandwich Type Human Histamine Receptor H4 ELISA Test Kit Highly Sensitive With Oem Service

Cat.No E6946Hu

Reagent Preparation
All reagents should be brought to room temperature before use.
Standard Reconstitute the 120μl of the standard (24ng/ml) with 120μl of standard diluent to generate a 12ng/ml standard stock solution. Allow the standard to sit for 15 mins with gentle agitation prior to making dilutions. Prepare duplicate standard points by serially diluting the standard stock solution (12ng/ml) 1:2 with standard diluent to produce 6ng/ml, 3ng/ml, 1.5ng/ml and 0.75ng/ml solutions. Standard diluent serves as the zero standard(0 ng/ml). Any remaining solution should be frozen at -20°C and used within one month. Dilution of standard solutions suggested are as follows:

12ng/mlStandard No.5120μl Original Standard + 120μl Standard Diluent
6ng/mlStandard No.4120μl Standard No.5 + 120μl Standard Diluent
3ng/mlStandard No.3120μl Standard No.4 + 120μl Standard Diluent
1.5ng/mlStandard No.2120μl Standard No.3 + 120μl Standard Diluent
0.75ng/mlStandard No.1120μl Standard No.2 + 120μl Standard Diluent

Wash Buffer Dilute 20ml of Wash Buffer Concentrate 25x into deionized or distilled water to yield 500 ml of 1x Wash Buffer. If crystals have formed in the concentrate, mix gently until the crystals have completely dissolved.

Standard Curve Range: 0.05ng/ml - 20ng/ml
Sensitivity: 0.018ng/ml
Size: 96 wells
*This product is for research use only, not for use in diagnosis procedures. It’s highly recommend to read this instruction entirely before use.

Intended Use
This sandwich kit is for the accurate quantitative detection of Human Histamine Receptor H4 (also known as HRH4) in serum, plasma, cell culture supernates, cell lysates, tissue homogenates.

Material Required But Not Supplied

  • 37°C±0.5°C incubator
  • Absorbent paper
  • Precision pipettes and disposable pipette tips
  • Clean tubes
  • Deionized or distilled water
  • Microplate reader with 450 ± 10nm wavelength filter


Assay Procedure
1. Prepare all reagents, standard solutions and samples as instructed. Bring all reagents to room temperature before use. The assay is performed at room temperature.
2. Determine the number of strips required for the assay. Insert the strips in the frames for use. The unused strips should be stored at 2-8°C.
3. Add 50μl standard to standard well. Note: Don’t add antibody to standard well because the standard solution contains biotinylated antibody.
4. Add 40μl sample to sample wells and then add 10μl anti-HRH4 antibody to sample wells, then add 50μl streptavidin-HRP to sample wells and standard wells ( Not blank control well ). Mix well. Cover the plate with a sealer. Incubate 60 minutes at 37°C.
5. Remove the sealer and wash the plate 5 times with wash buffer. Soak wells with at least 0.35 ml wash buffer for 30 seconds to 1 minute for each wash. For automated washing, aspirate all wells and wash 5 times with wash buffer, overfilling wells with wash buffer. Blot the plate onto paper towels or other absorbent material.
6. Add 50μl substrate solution A to each well and then add 50μl substrate solution B to each well. Incubate plate covered with a new sealer for 10 minutes at 37°C in the dark.
7. Add 50μl Stop Solution to each well, the blue color will change into yellow immediately.
8. Determine the optical density (OD value) of each well immediately using a microplate reader set to 450 nm within 10 minuets after adding the stop solution.
