Description

Human cardiac Troponin T (cTnT) ELISA Kit | SL2238Hu

Our human cardiac Troponin T (cTnT)ELISA kit is to assay cTnT levels inserum, plasma, culture media or any biological fluid.

Principle
This ELISA kit uses Sandwich-ELISA as the method. The Microelisa stripplate providedin this kit has been pre-coated with an antibody specific to cTnT. Standards or samplesareadded to the appropriate Microelisa stripplate wells and combined to the specific antibody.
Then a Horseradish Peroxidase (HRP)- conjugated antibody specific for cTnTis addedtoeach Microelisa stripplate well and incubated. Free components are washed away. TheTMBsubstrate solution is added to each well. Only those wells that contain cTnTandHRPconjugated cTnT antibody will appear blue in color and then turn yellow after the additionofthe stop solution. The optical density (OD) is measured spectrophotometricallyat awavelength of 450 nm. The OD value is proportional to the concentration of cTnT. Youcancalculate the concentration of cTnT in the samples by comparing the OD of the samples tothestandard curve.

Materials provided with the kit

Sample preparation

  1. Serum preparation

After collection of the whole blood, allow the blood to clot by leaving it undisturbed at room temperature. This usually takes 10-20 minutes. Remove the clot by centrifuging at 2,000-3,000 rpm for 20 minutes. If precipitates appear during reservation, the sample should be centrifugated again.

  1. Plasma preparation

Collect the whole blood into tubes with anticoagulant (EDTA or citrate). After incubated at room temperature for 10-20 minutes, tubes are centrifugated for 20 min at 2,000-3,000 rpm. Collect the supernatant carefully as plasma samples. If precipitates appear during reservation, the sample should be centrifugated again.

  1. Urine samples

Collect urine into aseptic tubes. Collect the supernatant carefully after centrifuging for 20 min at 2,000-3,000 rpm. If precipitates appear during reservation, the sample should be centrifugated again. The preparation procedure of cerebrospinal fluid and pleuroperitoneal fluid is the same as that of urine sample.

  1. Cell samples

If you want to detect the secretions of cells, collect culture supernatant into aseptic tubes. Collect the supernatant carefully after centrifuging for 20 min at 2,000-3,000 rpm. If you want to detect intracellular components, dilute the cells to 1X100/ml with PBS (pH 7.2-7.4). The cells were destroyed to release intracellular components by repeated freezing and thawing. Collect the supernatant carefully after centrifuging for 20 min at 2,000-3,000 rpm. If precipitates appear during reservation, the sample should be centrifugated again.

  1. Tissue samples

Tissue samples are cut, weighed, frozen in liquid nitrogen and stored at -80 for future use. The tissue samples were homogenized after adding PBS (pH 7.4). Samples should be operated at 4. Collect the supernatant carefully after centrifuging for 20 min at 2,000-3,000 rpm. Aliquot the supernatant for ELISA assay and future use.

Notes:

  1. Sample extraction and ELISA assay should be performed as soon as possible after sample collection. The samples should be extracted according to the relevant literature. If ELISA assay can not be performed immediately, samples can be stored at -20℃.Repeated freeze-thaw cycles should be avoided.
  2. Our kits can not be used for samples with NaN3 which can inhibit the activity of HRP.
