Human TNF-α

 

FOR RESEARCH USE ONLY

 

 

Assay range20 ng/L -400 ng/L 96 DETERMINATIONS

 

Purpose

 

This kit allows for the determination of TNF-α concentrations in Human serum.

 

 

Principle of the assay

 

The kit assay Human TNF-α level in the sample, use Purified Human TNF-α antibody to coat microtiter plate wells, make solid-phase antibody, then add TNF-α to wells, Combined TNF-α antibody which With HRP labeled, become antibody - antigen - enzyme-antibody complex, after washing Compley, 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 Human TNF-α in the samples is then determined by comparing the O.D. of the samples to the standard curve.

Calculate

 

Take the standard density as the horizontal, the OD value for the vertical ,draw the standard curve on graph paper, Find out the corresponding density according to the sample OD value by the Sample curve, multiplied by the dilution multiple, or calculate the straight line regression equation of the standard curve with the standard density and the OD value ,with the sample OD value in the equation, calculate the sample density, multiplied by the dilution factor,

the result is the sample actual density.

 

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.

Calculate

 

Take the standard density as the horizontal, the OD value for the vertical ,draw the standard curve on graph paper, Find out the corresponding density according to the sample OD value by the Sample curve, multiplied by the dilution multiple, or calculate the straight line regression equation of the standard curve with the standard density and the OD value ,with the sample OD value in the equation, calculate the sample density, multiplied by the dilution factor,

the result is the sample actual density.

 

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.
