Human Irisin ELISA TEST KIT

INTENDED USE

This kit allows for the determination of Irisin concentrations in Human serum, plasma and other biological fluids

Assay procedure

1.Dilute and add sample:Dilute Original density Standard as follow table:

2.add sample:Set blank wells separately (blank comparison wells don’t add sample and HRP-Conjugate reagent, other each step operation is same). testing sample well. Add 50μl of standard to Microelisa stripplate,add Sample dilution 40μl to testing sample well, then add testing sample 10μl (sample final dilution is 5-fold), add sample to wells , don’t touch the well wall as far as possible, and Gently mix.

3.Incubate: After closing plate with Closure plate membrane ,incubate for 30 min at 37℃.

4.Configurate liquid: 30-fold(or 20-fold) wash solution diluted 30-fold (or 20-fold) with distilled water and reserve.

5.washing:Uncover Closure plate membrane, discard Liquid, dry by swing, add washing buffer to every well, still for 30s then drain, repeat 5 times, dry by pat.

6.add enzyme:Add HRP-Conjugate reagent 50μl to each well, except blank well.

7.incubate:Operation with 3.

8.washing:Operation with 5.

9.color:Add Chromogen Solution A 50ul and Chromogen Solution B 50ul to each well, evade the light preservation for 10 min at 37℃

10.Stop the reaction:Add Stop Solution50μl to each well, Stop the reaction(the blue color change to yellow color).

11.assay:take blank well as zero , Read absorbance at 450nm after Adding Stop Solution and within 15min.

Specimen requirements

1.extract as soon as possible after Specimen collection,and according to the relevant literature, and should be experiment as soon as possible after the extraction. If it can’t, specimen can be kept in -20 ℃ to preserve, Avoid repeated freeze-thaw cycles.

2,Can’t detect the sample which contain NaN3, because NaN3 inhibits HRP active.

3.extract as soon as possible after Specimen collection,and according to the relevant literature, and should be experiment as soon as possible after the extraction. If it can’t, specimen can be kept in -20 ℃ to preserve, Avoid repeated freeze-thaw cycles.

4.Can’t detect the sample which contain NaN3, because NaN3 inhibits HRP active.

Important notes

• The kit takes out from the refrigeration environment should be balanced 15-30 minutes in the room temperature, ELISA plates coated if has not use up after opened, the plate should be stored in Sealed bag.
• washing buffer will Crystallization separation, it can be heated the water helps dissolve when dilute . Washing does not affect the result.
• add Sample with sampler Each step, And proofread its accuracy frequently, avoids the experimental error. add sample within 5 min, if the number of sample is much , recommend to use Volley .
• if the testing material content is excessively higher (The sample OD is bigger than the first standard well ),please dilute Sample (n-fold), Please diluente and multiplied by the dilution factor.(×n×5).
• Closure plate membrane only limits the disposable use, to avoid cross-contamination.
• The substrate evade the light preservation.
• Please according to use instruction strictly, The test result determination must take the microtiter plate reader as a standard.
• All samples, washing buffer and each kind of reject should according to infective material process.
• Do not mix reagents with those from other lots.
