Intended Use:
Canine BNP-32 EIA Kit is to be
utilised for in vitro quantitative determination of brain natriuretic peptice-32 (BNP-32) levels in urine, serum, plasma, CSF, any biological fluid, tissue homogenate or culture media.

Assay Principle:
1. Pre-coated wells with secondary antibody and also the non-specific binding sites have been blocked.
2. Secondary antibody is able to bind with the Fc fragment of the primary antibody, the Fab segment is competitively bound by both biotinylated peptides and the peptide standard or the targeted peptide in samples.
3. Biotinylated peptide can then interact with the SA-HRP, which then catalyzes the TMB substrate solution and hydrogen peroxide to form a blue coloured solution.
4. Reaction is stopped by adding hydrogen chloride, which forms a yellow coloured solution.
5. Intensity of the yellow solution is inversely proportional to the amount of the peptide in standard solutions or samples.
6. Unknown concentration of BNP-32 in samples can then be determined using this canine BNP-32 EIA assay by extrapolation from a standard curve.

Cross Reactivity:
BNP-32 (Canine)  100%.
BNP-32 (Porcine)  80%.
BNP-32 (Human or Rat)  0%.
Alpha ANP (1-28)  0%.
Endothelin-1  0%.
CNP-22  0%.

Brain natriuretic peptide (BNP 32) was first discovered in extracts of porcine brain, whereas within humans it is found to be made in the cardiac ventricles. Is a 32 a.a. polypeptide has been found to be secreted by the ventricles of heart when there is excessive stretching of myocytes. It is release alongside an NT-proBNP (76 amino acids amino terminal fragment). Elevated levels of BNP 32 and/or NT-proBNP within the blood are useful markers in the diagnosis of heart failure and acute congestive heart failure (CHF).
