Meteorin - Like Protein Sandwich ELISA Kit 96 Well Plate High Precision

Human High Precision and Specificity Meteorin-like Protein Sandwich ELISA Kit 96 Well Plate

*This product is for research use only, not for use in diagnosis procedures. It’s highly recommend to read this instruction entirely before use.

Precision

Intra-Assay Precision (Precision within an assay) Three samples of known concentration were tested on one plate to assess intra-assay precision.

Inter-Assay Precision (Precision between assays) Three samples of known concentration were tested in separate assays to assess inter-assay precision.

CV(%) = SD/mean x 100

Intra-Assay: CV<8%

Inter-Assay: CV<10%

Intended Use

This ELISA kit applies to the invitro quantitative determination of human METRNL concentrations in serum, plasma, tissue and other biological fluids.

Precautions

• Prior to use, the elisa assay 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 elisa assay kit should not be used beyond the expiration date.

Cat.No E3941Hu

Size: 96 wells

Standard Curve Range: 0.05ng/ml - 15ng/ml

Sensitivity: 0.023ng/ml

Reagent Preparation

All reagents should be brought to room temperature before use.

Standard Reconstitute the 120μl of the standard (16ng/ml) with 120μl of standard diluent to generate a 8ng/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 (8ng/ml) 1:2 with standard diluent to produce 4ng/ml, 2ng/ml, 1ng/ml and 0.5ng/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:

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.

Summary

1. Prepare all reagents, samples and standards.

2. Add sample and ELISA reagent into each well. Incubate for 1 hour at 37°C.

3. Wash the plate 5 times.

4. Add substrate solution A and B. Incubate for 10 minutes at 37°C.

5. Add stop solution and color develops.

6. Read the OD value within 10 minutes.

Calculation of Result

Construct a standard curve by plotting the average OD for each standard on the vertical (Y) axis against the concentration on the horizontal (X) axis and draw a best fit curve through the points on the graph. These calculations can be best performed with computer-based curve-fitting software and the best fit line can be determined by regression analysis.
