            Rat          IL-1β
            FOR RESEARCH USE ONLY
             
            Assay range: :: :1 ng/L -40 ng/L                                  96 determinations
            Purpose
            This  kit  allows  for  the  determination  of  IL-1βconcentrations  in  Rat  serum,  cell
            culture supernates and other biological fluids
             
            Principle of the assay
            The  kit assay Rat  IL-1β  level  in  the  sample, use Purified Rat  IL-1β  antibody  to  coat
            microtiter  plate wells, make  solid-phase  antibody,  then  add  IL-1β  to wells, Combined  IL-1β
            antibody which With HRP  labeled goat anti-Rat 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 Rat  IL-1β  in  the samples  is  then determined by comparing  the O.D. of
            the samples to the standard curve.
            Materials provided with the kit
            1  wash    solution  20ml×1bottle  7  Stop Solution  6ml×1 bottle
            2  HRP-Conjugate reagent  6ml×1 bottle  8  Standard(80ng/L)   0.5ml×1 bottle

            Specimen requirements
            1.  extract  as  soon  as  possible  after  Specimen  collection,and  according  to  the  relevant 
              2
            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.
            Assay procedure
            1.  Dilute and add sample:Dilute Original density Standard as follow table:
            40ng/L
            5 Standard  150µl Original density Standard+150µl Standard diluent
            20ng/L
            4 Standard  150µl 5 Standard+150µl Standard diluent
            10ng/L
            3 Standard  150µl 4 Standard+150µl Standard diluent
            5ng/L
            2 Standard  150µl 3 Standard +150µl Standard diluent
            2.5ng/L
            1 Standard  150µl 2 Standard +150µl Standard diluent
            2.add  sample:Set  blank  wells  separay  (blank  comparison  wells  don’t  add  sample  and
            HRP-Conjugate reagent, other each step operation is same). testing sample well. 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  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.

            Add Stopp Solution
             
             
            Read absorbance at 450nm within 15 min
             
             
            calculate
            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 
              4
            sample OD value in the equation, calculate the sample density, multiplied by the dilution factor,
            the result is the sample actual density.
            Important notes
            1.  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.
            2.  washing  buffer  will  Crystallization  separation,  it  can  be  heated  the  water  helps  dissolve
            when dilute . Washing does not affect the result.
            3.  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 .
            4.  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).
            5.  Closure plate membrane only limits the disposable use, to avoid cross-contamination.
            6.  The substrate evade the light preservation.
            7.  Please  according  to  use  instruction  strictly,  The  test  result  determination must  take  the
            microtiter plate reader as a standard.
            8.  All samples, washing buffer and each kind of  reject should according  to  infective material
            process.
            9.  Do not mix reagents with those from other lots.
             
            Storage and validity
            1.Storage:    2-8℃.
            2.validity:  six months
