檢測原理

試劑盒采用雙抗體夾心法酶聯(lián)免疫吸附試驗(yàn)(ELISA)。往預(yù)先包被大鼠CXC趨化因子配體9CXCL9)捕獲抗體的包被微孔中,依次加入標(biāo)本、標(biāo)準(zhǔn)品、HRP標(biāo)記的檢測抗體,經(jīng)過溫育并*洗滌。用底物TMB顯色,TMB在過氧化物酶的催化下轉(zhuǎn)化成藍(lán)色,并在酸的作用下轉(zhuǎn)化成終的黃色。顏色的深淺和樣品中的大鼠CXC趨化因子配體9CXCL9)呈正相關(guān)。用酶標(biāo)儀在450nm 波長下測定吸光度(OD 值),計(jì)算樣品濃度。

樣品收集、處理及保存方法

1.  血清:使用不含熱原和內(nèi)毒素的試管,操作過程中避免任何細(xì)胞刺激,收集血液后,3000轉(zhuǎn)離心10分鐘將血清和紅細(xì)胞迅速小心地分離。

2.  血漿:EDTA、檸檬酸鹽或肝素抗凝。3000轉(zhuǎn)離心30分鐘取上清。

3.  細(xì)胞上清液:3000轉(zhuǎn)離心10分鐘去除顆粒和聚合物。

4.  組織勻漿:將組織加入適量生理鹽水搗碎。3000轉(zhuǎn)離心10分鐘取上清。

5.  保存:如果樣本收集后不及時(shí)檢測,請按一次用量分裝,凍存于-20℃,避免反復(fù)凍融,在室溫下解凍并確保樣品均勻地充分解凍。

自備物品

  • 酶標(biāo)儀(450nm)
  • 高精度加樣器及槍頭:0.5-10uL、2-20uL、20-200uL、200-1000uL
  • 37℃恒溫箱

操作注意事項(xiàng)

  1.   試劑盒保存在2-8℃,使用前室溫平衡60分鐘。從冰箱取出的濃縮洗滌液會有結(jié)晶,這屬于正?,F(xiàn)象,水浴加熱使結(jié)晶*溶解后再使用。樣本在使用也要在室溫平衡60分鐘。
  2.   實(shí)驗(yàn)中不用的板條應(yīng)立即放回自封袋中,密封(低溫干燥)保存。
  3.   預(yù)處理后的樣本無需稀釋,直接取10μL加樣即可。
  4.   嚴(yán)格按照說明書中標(biāo)明的時(shí)間、加液量及順序進(jìn)行溫育操作。
  5.   所有液體組分使用前充分搖勻。

Rat CXC-chemokine ligand 9 (CXCL9) ELISA Kit instruction

 

Intended use

This CXCL9 ELISA kit is intended Laboratory for Research use only and is not for use in diagnostic or therapeutic procedures. The Stop Solution changes the color from blue to yellow and the intensity of the color is measured at 450 nm using a spectrophotometer. In order to measure the concentration of CXCL9 in the sample, this CXCL9 ELISA Kit includes a set of calibration standards. The calibration standards are assayed at the same time as the samples and allow the operator to produce a standard curve of Optical Density versus CXCL9 concentration. The concentration of CXCL9 in the samples is then determined by comparing the O.D. of the samples to the standard curve.

Sample collection and storages

Serum - Use a serum separator tube and allow samples to clot for 30 minutes before centrifugation for 10 minutes at approximately 3000×g. Remove serum and assay immediately or aliquot and store samples at -20℃ or -80℃.Avoid repeated freeze-thaw cycles

Plasma - Collect plasma using EDTA or heparin as an anticoagulant. Centrifuge samples for 30 minutes at 3000×g at 2-8℃ within 30 minutes of collection. Store samples at -20℃or -80℃. Avoid repeated freeze-thaw cycles.

Cell culture supernates and other biological fluids - Remove particulates by centrifugation and assay immediately or aliquot and store samples at -20℃or -80℃. Avoid repeated freeze-thaw cycles.

Note:  The samples should be centrifugated adequately and no hemolysis or granule was allowed.

Materials required but not supplied

1.  Standard microplate reader(450nm)

2.  Precision pipettes and Disposable pipette tips.

3.  37 ℃ incubator

Precautions

1.  Do not substitute reagents from one kit to another. Standard, conjugate and microplates are matched for optimal performance. Use only the reagents supplied by manufacturer.

2.  Do not remove microplate from the storage bag until needed. Unused strips should be stored at 2-8°C in their pouch with the desiccant provided.

3.  Mix all reagents before using.

Remove all kit reagents from refrigerator and allow them to reach room temperature ( 20-25°C)

Reagent preparation

20×wash solution:Dilute with Distilled or deionized water 1:20.

Assay procedure

1.  Prepare all reagents before starting assay procedure. It is recommended that all Standards and Samples be added in duplicate to the Microelisa Stripplate.

2.  Add standard: Set Standard wells, testing sample wells. Add standard 50μl to standard well.

3.  Add Sample: Add testing sample 10μl Then add sample diluent 40μl to testing sample well; Blank well doesnt add anyting.

4.  Add 10l of HRP-conjugate reagent to each well, cover with an adhesive strip and incubate for 60 minutes at 37°C. 

5.  Aspirate each well and wash, repeating the process four times for a total of five washes. Wash by filling each well with Wash Solution (400μl) using a squirt bottle, manifold dispenser or autowasher. Complete removal of liquid at each step is essential to good performance. After the last wash, remove any remaining Wash Solution by aspirating or decanting. Invert the plate and blot it against clean paper towels.

6.  Add chromogen solution A 50μl and chromogen solution B 50μl to each well. Gently mix and incubate for 15 minutes at 37°C. Protect from light.

7.  Add 50μl Stop Solution to each well. The color in the wells should change from blue to yellow. If the color in the wells is green or the color change does not

 

 

appear uniform, gently tap the plate to ensure thorough mixing.

8.  Read the Optical Density (O.D.) at 450 nm using a microtiter plate reader within 15 minutes.

Calculation of results

  • This standard curve is used to determine the amount in an unknown sample. The standard curve is generated by plotting the average O.D. (450 nm) obtained for each of the six standard concentrations on the vertical (Y) axis versus the corresponding concentration on the horizontal (X) axis.
  • First, calculate the mean O.D. value for each standard and sample. All O.D. values, are subtracted by the mean value of the zero standard before result interpretation. Construct the standard curve using graph paper or statistical software.
  • To determine the amount in each sample, first locate the O.D. value on the Y-axis and extend a horizontal line to the standard curve. At the point of intersection, draw a vertical line to the X-axis and read the corresponding concentration.
  • Any variation in operator, pipetting and washing technique, incubation time or temperature, and kit age can cause variation in result. Each user should obtain their own standard curve.
  • The sensitivity by this assay is 1.0 pg/mL.
  • Standard curve
