人网膜素(omentin) 酶联免疫分析( ELISA 试剂盒

实验 目的 :本试剂盒仅供研究使用,用于测定人血清,血浆及相关液体样本中网膜素(omentin)的含量。

实验原理:

本试剂盒应用双抗体夹心法测定标本中人网膜素 (omentin) 水平。用纯化的人网膜素 (omentin) 抗体包被微孔板,制成固相抗体,往包被单抗的微孔中依次加入网膜素 (omentin) 再与HRP标记的网膜素 (omentin) 抗体结合,形成抗体-抗原-酶标抗体复合物,经过*洗涤后加底物TMB显色。TMBHRP酶的催化下转化成蓝色,并在酸的作用下转化成zui终的黄色。颜色的深浅和样品中的网膜素 (omentin) 呈正相关。用酶标仪在450nm波长下测定吸光度(OD值),通过标准曲线计算样品中人网膜素 (omentin) 浓度。

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/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/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/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/分)。仔细收集上清。检测细胞内的成份时,用PBSPH7.2-7.4)稀释细胞悬液,细胞浓度达到100/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分钟左右(2000-3000/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PBSPH7.4。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PBSPH7.4),用手工或匀浆器将标本匀浆充分。离心20分钟左右(2000-3000/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。

Drug Names

Generic Name Human omentin ELISA Kit .

Purpose

This kit allows for the determination of omentin concentrations in Human serum, plasma, and other biological fluids .

Principle of the assay

The kit assay Human omentin level in the sample use Purified Human omentin antibody to coat microtiter plate wells , make solid-phase antibody, then add omentin to wells , Combined omentin 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 omentin in the samples is then determined by comparing the O.D. of the samples to the standard curve .

Specimen requirements

  1. serum - coagulation at room temperature 10-20 mins centrifugation 20-min at the speed of 2000-3000 r.p.m. remove supernatant, If precipitation appeared, Centrifugal again.
  2. plasma - use suited EDTA or citrate plasma as an anticoagulant,mix 10-20 mins ,centrifugation 20-min at the speed of 2000-3000 r.p.m. remove supernatant, If precipitation appeared, Centrifugal again.
  3. Urine -collect sue a sterile container, centrifugation 20-min at the speed of 2000-3000 r.p.m. remove supernatant, If precipitation appeared, Centrifugal again. The Operation of Hydrothorax and cerebrospinal fluid Reference to it.
  4. cell culture supernatant -detect secretory components, collect sue a sterile container, centrifugation 20-min at the speed of 2000-3000 r.p.m. remove supernatant,detect the composition of cells, Dilut cell suspension with PBS PH7.2-7.4 , Cell concentration reached 1 million / ml, repeated freeze-thaw cycles , damage cells and release of intracellular components, centrifugation 20-min at the speed of 2000-3000 r.p.m. remove supernatant, If precipitation appeared, Centrifugal again.
  5. Tissue samples - After cutting samples, check the weight,add PBS PH7.2-7.4 , Rapidly frozen with liquid nitrogen, maintain samples at 2-8after melting,add PBS PH7.4 , Homogenized by hand or Grinders, centrifugation 20-min at the speed of 2000-3000 r.p.m. remove supernatant.
  6. extract as soon as possible after Specimen collection, and according to the relevant 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 .
  7. Can’t detect the sample which contain NaN3, because NaN3 inhibits HRP active.
