Materials provided with the kit

Specimen requirements

• 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.
• 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.
• 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.
• 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.
• Tissue samples- After cutting samples, check the weight,add PBS(PH7.2-7.4), Rapidly frozen with liquid nitrogen, maintain samples at 2-8℃ after melting,add PBS(PH7.4), Homogenized by hand or Grinders, centrifugation 20-min at the speed of 2000-3000 r.p.m. remove supernatant.
• 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.
• Can’t detect the sample which contain NaN3, because NaN3 inhibits HRP active.

Principle

This ELISA kit uses Sandwich-ELISA as the method. The Microelisa stripplate provided in this kit has been pre-coated with an antibody specific to IL2R . Standards or samples are added to the appropriate Microelisa stripplate wells and combined to the specific antibody. Then a Horseradish Peroxidase (HRP)- conjugated antibody specific for IL2R is added to each Microelisa stripplate well and incubated. Free components are washed away. The TMB substrate solution is added to each well. Only those wells that contain IL2R and HRP conjugated thrombomodulin antibody will appear blue in color and then turn yellow after the addition of the stop solution. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm. The OD value is proportional to the concentration of IL2R . You can calculate the concentration of IL2R in the samples by comparing the OD of the samples to the standard curve.

Notes:

• Store the kit at 4°C upon receipt.The kit should be equilibrated to room temperature before the assay. Remove any unneeded strips from IL2R Antibody-Coated plate, reseal them in zip-lock foil and keep at 4°C.
• Precipitates may appear in concentrated washing buffer. Please heat the buffer to dissolve all the precipitates, which will not affect the results.
• Accurate pipette should be used to avoid experimental error. Samples should be added to the Microplate in less than 5 minutes. If a large number of samples are included, multiple channel pipette is recommended.
• Standard curve should be included in every assay. Replicate wells are recommended. If the OD value of the sample is greater than the first well of standards, please dilute the sample (n times) before test. When calculating the original thrombomodulin concentration, please multiply the total dilution factor (XnX5).
• In order to avoid cross-contamination, Microplate sealers are for one-time use only.
• Please keep Substrate away from light.
• All the operation should be accordance with the manufacturer's instructions strictly. The results determined by the Microtiter Plate Reader.
• All the samples, washing buffer and wastes should be treated as infectious agents.
• Reagents from different lots should not be mixed.
