【資料簡介�

牛口蹄疫O型抗�(FMD-O-Ag)試劑盒齊一生物�本試劑僅供研究使�       目的:本試劑盒用于測定牛血清,血漿及相關液體樣本中口蹄疫O型抗�(FMD-O-Ag)水平�
實驗原理�
  本試劑盒采用雙抗體夾心酶聯免疫法(ELISA)測定標本中牛口蹄疫O型抗�(FMD-O-Ag)水平。用純化的牛口蹄疫O型抗�(FMD-O-Ag)抗體包被微孔板,制成固相抗體,可與樣品中口蹄疫O型抗�(FMD-O-Ag)結合,經洗滌除去未結合的抗原和其他成分后再與HRP標記的口蹄疫O型抗�(FMD-O-Ag)抗體結合,形成抗�-抗原-酶標抗體復合物,經過*洗滌后加底物TMB顯色。TMB在HRP酶的催化下轉化成藍色,并在酸的作用下轉化成zui終的黃色。用酶標儀�450nm波長下測定吸光度(OD值),與CUTOFF值相比較,從而判定標本中牛口蹄疫O型抗�(FMD-O-Ag)的存在與否�

7.Can’t detect the sample which contain NaN3, because NaN3 inhibits HRP active.
Assay procedure
1.Number: to sample correspond microtitration well and Number Sequence, each plate should be set feminine comparison 2 wells, masculine comparison 2 wells, blank comparison 1 well(don’t add sample and HRP-Conjugate reagent to blank comparison well, other each step the operation are same).
2.add sample:separay add Positive control and Negative control 50μl to the Positive and Negative well . add Sample dilution 40μl to testing sample well, then add testing sample 10μl. add sample to the bottom of ELISA plates coated well , 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 until 600ml,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 50μlto each well, except the 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 15 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.
Determine the result
Test validity: the average of Positive control well≥1.00; the average of Negative control well ≤0.10.
Calculate Critical(CUT OFF) : Critical= the average of Negative control well + 0.15.
Negative control: sample OD< Calculate Critical(CUT OFF) is FMD-O-Ag Negative control.
Positive control: ample OD≥ Calculate Critical(CUT OFF) is FMD-O-Ag Positive control.
Important notes
1.Please according to use instruction strictly, Do not mix reagents with those from other lots.
2.The kit takes out from the refrigeration environment should be balanced 15-30 minutes in the room temperature  then use, ELISA plates coated if has not use up after opened, the plate should be stored in Sealed bag.
3.washing buffer will Crystallization separation, it can be heated the water helps dissolve when dilute . Washing does not affect the result.
4.Closure plate membrane only limits the disposable use, in order to avoid the overlapping pollution
5.The substrate please evade the light preservation.
6.The test result determination must take the microtiter plate reader as a standard, when use dual-wavelength to assay, Reference wavelength is 630nm.
7.All samples, washing buffer and each kind of reject should according to infective material process. Stopp Solution is 2M sulphuric acid. You must pay attention to safe when use .


Storage and validity
1.Storage�  2-8�.
2.validity� six months.
