Principle of the assay

The kit assay Human IFN-γ level in the sample, use Purified Human IFN-γ antibody to coat microtiter plate wells, make solid-phase antibody, then add IFN-γ to wells, Combined IFN-γ antibody which With HRP labeled, become antibody - antigen - enzyme-antibody complex, after washing Completely, Add TMB substrate solution,TMB substrate becomes blue color At HRP enzyme-catalyzed, reaction is terminated by the addition of a sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450 nm. The concentration of IFN-γ in the samples is then determined by comparing the O.D. of the samples to the standard curve.

Features:

• Product Name: IFN-γ
• Storage Condition: 2-8℃
• Template Dna: Not Included
• Quality Control: Endonuclease And Exonuclease Activity Tested

Technical Parameters:

Specimen requirements

• 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.
• 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.
