Human NT proBNP ELISA Kit - Information

The ELISA Genie N-Terminal Pro-Brain Natriuretic Peptide / NT-proBNP ELISA Kit can assay for N-Terminal Pro-Brain Natriuretic Peptide / NT-proBNP in the following samples: serum, blood, plasma, cell culture supernatant and other related supernatants and tissues.

How our N-Terminal Pro-Brain Natriuretic Peptide / NT-proBNP ELISA Kits Work?

The ELISA Genie (enzyme-linked immunosorbent assays) assay kits are designed for the quantitative measurement of analytes in a wide variety of samples. As today's scientists demand high quality consistent data for high impact journals, ELISA Genie have developed our range of sensitive, fast and reliable ELISA kit assays to meet and exceed those demands. Our assay kits use a quantitative sandwich ELISA technique and each kit comes with highly specific antibodies pre-coated onto a 96-well microtiter plate.

At ELISA Genie we understand the need for speed! Therefore, we have developed an ultra-fast protocol meaning you achieve your results rapidly. So, once you have prepared and plated your samples, blanks and standards, you simply incubate with a highly specific biotin-conjugated primary antibody and Avidin conjugated to Horseradish Peroxidase (HRP) and incubate for the appropriate length of time. After washing the plate according to the protocol and addition of the TMB (3,3',5,5'-Tetramethylbenzidine) solution, the appearance of a blue colour should be detected due to an enzymatic reaction catalysed by HRP. Next step is the addition of the Stop Solution which terminates the HRP reaction and the blue colour turns yellow with the signal intensity measured on a plate reader at 450nm. The amount of bound N-Terminal Pro-Brain Natriuretic Peptide / NT-proBNP is proportional to the signal generated by the reaction meaning the kit assay gives you a quantitative measurement of the analyte in your samples.

Matrices listed below were spiked with certain level of NT-proBNP and the recovery rates were calculated by comparing the measured value to the expected amount of NT-proBNP in samples.

Matrix Recovery range(%) Average(%)
serum(n=5) 85-104 92
EDTA plasma(n=5) 90-104 98
UFH plasma(n=5) 93-100 97

The linearity of the kit was assayed by testing samples spiked with appropriate concentration of NT-proBNP and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected.

Sample 1:2 1:4 1:8 1:16
serum(n=5) 90-101% 85-105% 85-105% 92-105%
EDTA plasma(n=5) 85-99% 84-98% 88-100% 86-101%
UFH plasma(n=5) 81-99% 81-88% 86-100% 80-93%

Intra-Assay: CV<8%
Inter-Assay: CV<10%
