小鼠口疮病毒抗体 (ORFV-Ab)ELISA试剂盒

小鼠口疮病毒抗体 (ORFV-Ab)酶联免疫分析（ELISA）试剂盒使用说明书
本试剂仅供研究使用 目的：本试剂盒用于测定小鼠血清，血浆及相
关液体样本中口疮病毒抗体 (ORFV-Ab)水平。
小鼠口疮病毒抗体 (ORFV-Ab)ELISA试剂盒实验原理：
本试剂盒采用双抗原夹心法测定血清或血浆中小鼠口疮病毒抗体 (ORFV-Ab)。用纯化的
小鼠口疮病毒抗原包被微孔板， 制成固相抗体， 可与样品中口疮病毒抗体(ORFV-Ab)相结合，
经洗涤除去未结合的抗体和其他成分后再与 HRP 标记的口疮病毒抗原结合，经过彻底洗涤
后加底物 TMB 显色。TMB 在 HRP 酶的催化下转化成蓝色，并在酸的作用下转化成最终的
黄色。用酶标仪在 450nm 波长下测定吸光度（OD 值），与 CUTOFF 值相比较，从而判定
标本中小鼠口疮病毒抗体(ORFV-Ab)的存在与否。

小鼠口疮病毒抗体 (ORFV-Ab)ELISA试剂盒样本处理及要求：
1. 血清：室温血液自然凝固 10-20 分钟，离心 20 分钟左右（2000-3000转/分）。仔细收集
上清，保存过程中如出现沉淀，应再次离心。
2. 血浆：应根据标本的要求选择 EDTA或柠檬酸钠作为抗凝剂，混合 10-20 分钟后，离心
20分钟左右（2000-3000转/分）。仔细收集上清，保存过程中如有沉淀形成，应该再次
离心。
3. 尿液：用无菌管收集，离心 20分钟左右（2000-3000转/分）。仔细收集上清，保存过程
中如有沉淀形成，应再次离心。胸腹水、脑脊液参照实行。
4. 细胞培养上清：检测分泌性的成份时，用无菌管收集。离心 20分钟左右（2000-3000 转/
分）。仔细收集上清。检测细胞内的成份时，用 PBS（PH7.2-7.4）稀释细胞悬液，细胞
浓度达到 100万/ml 左右。通过反复冻融，以使细胞破坏并放出细胞内成份。离心 20 分2
钟左右（2000-3000转/分）。仔细收集上清。保存过程中如有沉淀形成，应再次离心。
5. 组织标本：切割标本后，称取重量。加入一定量的 PBS，PH7.4。用液氮迅速冷冻保存备
用。标本融化后仍然保持 2-8℃的温度。加入一定量的 PBS（PH7.4），用手工或匀浆器
将标本匀浆充分。离心 20分钟左右（2000-3000 转/分）。仔细收集上清。分装后一份待
检测，其余冷冻备用。
6. 标本采集后尽早进行提取，提取按相关文献进行，提取后应尽快进行实验。若不能马上
进行试验，可将标本放于-20℃保存，但应避免反复冻融.
7. 不能检测含 NaN3的样品，因 NaN3 抑制辣根过氧化物酶的（HRP）活性。
操作步骤：
1. 编号：将样品对应微孔按序编号，每板应设阴性对照 2孔、阳性对照 2 孔、空白对照 1
孔（空白对照孔不加样品及酶标试剂，其余各步操作相同）
2. 加样：分别在阴、阳性对照孔中加入阴性对照、阳性对照 50μl。然后在待测样品孔先
加样品稀释液 40μl，然后再加待测样品 10μl。加样将样品加于酶标板孔底部，尽量不
触及孔壁，轻轻晃动混匀，
3. 温育：用封板膜封板后置 37℃温育 30分钟。
4. 配液：将 30（48T 的 20倍）倍浓缩洗涤液加蒸馏水至 600ml 后备用
5. 洗涤：小心揭掉封板膜，弃去液体，甩干，每孔加满洗涤液，静置 30 秒后弃去，如此
重复 5次，拍干。
6. 加酶：每孔加入酶标试剂 50μl，空白孔除外。
7. 温育：操作同 3。
8. 洗涤：操作同 5。
9. 显色：每孔先加入显色剂 A 50μl，再加入显色剂 B 50μl，轻轻震荡混匀，37℃避光显色
15分钟
10. 终止：每孔加终止液 50μl，终止反应（此时蓝色立转黄色）。
11. 测定：以空白空调零，450nm 波长依序测量各孔的吸光度（OD 值）。 测定应在加终
止液后 15 分钟以内进行。
结果判定：
试验有效性：阳性对照孔平均值≥1.00; 阴性对照平均值≤0.15
临界值（CUT OFF）计算：临界值=阴性对照孔平均值+0.10（阴性对照平均值低于 0.05
按 0.05计算）
阴性判定：样品 OD 值< 临界值（CUT OFF）者为口疮病毒抗体(ORFV-Ab)阴性
阳性判定：样品 OD 值≥ 临界值（CUT OFF）者为口疮病毒抗体(ORFV-Ab)阳性
注意事项
1．操作严格按照说明书进行，本试剂不同批号组分不得混用。
2．试剂盒从冷藏环境中取出应在室温平衡 15-30 分钟后方可使用，酶标包被板开封后如未
用完，板条应装入密封袋中保存。
3．浓洗涤液可能会有结晶析出，稀释时可在水浴中加温助溶，洗涤时不影响结果。
4．封板膜只限一次性使用，以避免交叉污染。
5．底物请避光保存。
6．试验结果判定必须以酶标仪读数为准，使用双波长检测时，参考波长为 630nm
7．所有样品，洗涤液和各种废弃物都应按传染物处理。终止液为 2M的硫酸，使用时必须

Generic Name：Mouse Orf virus antibody (ORFV-Ab) ELISA Kit.
Purpose
This kit allows for the determination of ORFV-Ab in Mouse serum, and
other biological fluids.
Principle of the assay
The kit assay ORFV-Ab level in the sample，use Purified PCP antigen to
coat microtiter plate wells, make solid-phase antigen , then add ORFV-Ab to
wells, Combined With ORFV-Ab, after washing and removing non-combinative
antibody and other components ,then Combined PCP antigen which With HRP
labeled, 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. Compared with the
CUTOFF value, according to this to judge ORFV-Ab exist in the sample or not.5

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：separately 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,7
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 ORFV-Ab
Negative control.
Positive control: ample OD≥ Calculate Critical(CUT OFF) is ORFV-Ab
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 if8
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 .
