Anwendungsinformationen

Probenmenge: 50 µL

Plattentyp: Pre-coated

Protokoll: This kit is based on competitive enzyme-linked immuno-sorbent assay technology. An antibody is pre-coated onto a 96-well plate. Standards, test samples, and biotin-conjugated reagent are added to the wells and incubated. A competitive inhibition reaction takes place between the biotin-labelled NT-ProBNP and the unlabelled- NT-ProBNP on the pre-coated antibody. The HRP-conjugated reagent is then added, and the whole plate is incubated. Unbound conjugates are removed using wash buffer at each stage. TMB substrate is used to quantify the HRP enzymatic reaction. After TMB substrate is added, only wells that contain sufficient NT-ProBNP will produce a blue coloured product, which then changes to yellow after adding the acidic stop solution. The intensity of the color yellow is inversely proportional to the NT-ProBNP amount bound on the plate. The OD is measured spectrophotometrically at 450 nm in a microplate reader, from which the concentration of NT-ProBNP can be calculated.

Aufbereitung der Reagenzien:

This procedure is provided for reference only. The product manual may differ slightly. The product should be used as stated on the product manual included and delivered together with the product.

• 1) Standard: Prepare the standard with the recommended volume of Standard Diluent Buffer, to make the standard solution. Then use the Standard Diluent buffer to carry out serial dilutions of the standard solution, as instructed in the Protocol.

• 2) Wash Buffer: Dilute the concentrated Wash Buffer with distilled water, as instructed in the Protocol.

• 3) Detection Reagent Preparation: Calculate the total volume of working solution required. Dilute Detection Reagent A and Detection Reagent B with Diluent A and Diluent B, respectively, at 1:100.

Testdurchführung:

This procedure is provided for reference only. The product manual may differ slightly. The product should be used as stated on the product manual included and delivered together with the product.

• 1) Set standard, test samples and control wells.

• 2) Aliquot 50 μL of diluted standard into the standard wells.

• 3) Aliquot 50 μL of Standard Diluent buffer into the control (zero) well.

• 4) Aliquot 50 μL of diluted samples into the sample wells.

• 5) Immediately aliquot 50 μL of Detection Reagent A to each well. Incubate for 1 hr at 37 °C.

• 6) Wash 3 times.

• 7) Aliquot 100 μL of Detection Reagent B to each well. Incubate for 30 mins at 37 °C.

• 8) Wash 5 times.

• 9) Aliquot 90 μL of TMB Substrate to each well. Incubate for 10-20 mins at 37 °C.

• 10) Aliquot 50 μL of Stop Solution.

• 11) Measure the OD at 450 nm.

Ergebnisberechnung:

This assay is competitive, therefore there is an inverse correlation between NT-ProBNP concentration in the sample and the absorbance measured. Create a graph with the log of the standard concentration (y-axis) and average absorbance measured (x-axis). Apply a best fit trendline through the standard points. The NT-ProBNP concentration of the samples can be interpolated from the standard curve.

Testpräzision: Intra-assay Precision (Precision within an assay): 3 samples with low, medium and high levels of N-Terminal Pro-Brain Natriuretic Peptide were were tested 20 times on one plate, respectively.

Inter-assay Precision (Precision between assays): 3 samples with low, medium and high levels of N-Terminal Pro-Brain Natriuretic Peptide were tested on 3 different plates, 8 replicates in each plate.

CV (%) = (Standard Deviation / mean) x 100

Intra-Assay: CV<10%

Handhabung

Lagerung: 4 °C

Informationen zur Lagerung: Shipped at 4°C. Upon receipt, store the kit according to the storage instruction in the kit's manual.The stability of the kit is determined by the rate of activity loss. The loss rate is less than 5% within the expiration date under appropriate storage conditions. To minimize performance fluctuations, operation procedures and lab conditions should be strictly controlled. It is also strongly suggested that the whole assay is performed by the same user throughout.

Haltbarkeit: 6 months
