96 wells High sensitive ELISA Kit for Rat Interleukin 1 Alpha

 

Cat.No E0118Ra

Standard Curve Range: 1ng/L - 300ng/L

Sensitivity: 0.48ng/L

Size: 96 wells

Storage: Store the reagents at 2-8°C. For over 6-month storage refer to the expiration date keep it at -20°C. Avoid repeated thaw cycles. If individual reagents are opened it is recommended that the kit be used within 1 month.

* 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 Rat Interleukin 1 Alpha (also known as IL-1A) in serum, plasma, cell culture supernates, cell lysates, tissue homogenates.

 

Assay Principle

This kit is an Enzyme-Linked Immunosorbent Assay (ELISA). The plate has been pre-coated with Rat IL-1A antibody. IL-1A present in the sample is added and binds to antibodies coated on the wells. And then biotinylated Rat IL-1A Antibody is added and binds to IL-1A in the sample. Then Streptavidin-HRP is added and binds to the Biotinylated IL-1A antibody. After incubation unbound Streptavidin-HRP is washed away during a washing step. Substrate solution is then added and color develops in proportion to the amount of Rat IL-1A. The reaction is terminated by addition of acidic stop solution and absorbance is measured at 450 nm.

 

Precautions

  • Prior to use, the kit and sample should be warmed naturally to room temperature 30 minutes.
  • This instruction must be strictly followed in the experiment.
  • Once the desired number of strips has been removed, immediately reseal the bag to protect the remain from deterioration. Cover all reagents when not in use.
  • Make sure pipetting order and rate of addition from well-to-well when pipetting reagents.
  • Pipette tips and plate sealer in hand should be clean and disposable to avoid cross-contamination.
  • Avoid using the reagents from different batches together.
  • Substrate solution B is sensitive to light, don’t expose substrate solution B to light for a long time.
  • Stop solution contains acid. Please wear eye, hand and skin protection when using this material. Avoid contact of skin or mucous membranes with kit reagent.
  • The kit should not be used beyond the expiration date.

Wash Buffer Dilute 20ml of Wash Buffer Concentrate 30x 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.

 

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-IL-1A 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.
