小鼠弓形蟲(chóng)酶聯(lián)免疫分析(ELISA)試劑盒使用說(shuō)明書
本試劑僅供研究使用 目的:本試劑盒用于測(cè)定小鼠血清,血漿及相關(guān)液體樣本中弓形蟲(chóng)的表達(dá)。
實(shí)驗(yàn)原理:
本試劑盒采用雙抗體夾心酶聯(lián)免疫法(ELISA)測(cè)定標(biāo)本中小鼠弓形蟲(chóng)。用純化的弓形蟲(chóng)抗體包被微孔板,制成固相抗體,可與樣品中弓形蟲(chóng)相結(jié)合,經(jīng)洗滌除去未結(jié)合的抗體和其他成分后再與HRP標(biāo)記的弓形蟲(chóng)抗體結(jié)合,形成抗體-抗原-酶標(biāo)抗體復(fù)合物,經(jīng)過(guò)*洗滌后加底物TMB顯色。TMB在HRP酶的催化下轉(zhuǎn)化成藍(lán)色,并在酸的作用下轉(zhuǎn)化成zui終的黃色。用酶標(biāo)儀在450nm波長(zhǎng)下測(cè)定吸光度(OD值),與CUTOFF值相比較,從而判定標(biāo)本中小鼠弓形蟲(chóng)的存在與否。

Drug Names
Generic Name:Mouse Toxoplasma gondii (TOX )ELISA Kit.
Purpose
This kit allows for the determination of TOX in Mouse serum, and other biological fluids.
Principle of the assay
The kit assay TOX level in the sample,use Purified TOX antibody to coat microtiter plate wells, make solid-phase antibody, then add TOX to wells, Combined With TOX, after washing and removing non-combinative antibody and other components ,then Combined TOX antibody which with HRP labeled become antigen - antibody - enzyme- antigen 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. Compared with the CUTOFF value, according to this to judge TOX exist in the sample or not.

Specimen requirements
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 100μl to the Positive and Negative well . add Sample dilution 50μl to testing sample well, then add testing sample 50μl. 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: 20-fold wash solution diluted with distilled water until 1000ml,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 ≤0.15.
Calculate Critical(CUT OFF) : Critical= the average of Negative control well + 0.10.
Negative control: sample OD< Calculate Critical(CUT OFF) is TOX Negative control.
Positive control: ample OD≥ Calculate Critical(CUT OFF) is TOX 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.
