  • Product overview

    Abcam’s ANP (NPPA) Rat in vitro ELISA (Enzyme-Linked Immunosorbent Assay) kit is designed for the quantitative measurement of ANP concentrations in cell culture supernatants, tissue-extract, serum and plasma.

    An ANP specific antibody has been precoated onto 96-well plates and blocked. Standards or test samples are added to the wells and subsequently an ANP specific biotinylated detection antibody is added and then followed by washing with wash buffer. Streptavidin-Peroxidase Conjugate is added and unbound conjugates are washed away with wash buffer. TMB is then used to visualize Streptavidin-Peroxidase enzymatic reaction. TMB is catalyzed by Streptavidin-Peroxidase to produce a blue color product that changes into yellow after adding acidic stop solution. The density of yellow coloration is directly proportional to the amount of ANP captured in plate.

We tested mouse samples only at two different concentrations, which is not ideal to verify linearity. We did get a significant signal, but there is not a satisfying reduction in signal at dilution 1/10 vs the neat sample. The rat values titrate out bet...

The lab has testd several plasma and serum samples, all at no dilution (1x). The value may be 0.3 ng/ml for human plasma/serum, but it may be higher or lower depending on the sample. Each sample is different and some optimization may be requi...

Human plasma and serum has been tested with this kit. Rat EDTA plasma has also been tested, so human EDTA plasma should work with the kit as well.

Thank you for your enquiry regarding ab108797 and ab108815. I am sorry to hear that you have been experiencing problems using this product in the application that you wish.

Thank you for contacting Abcam regarding this issue. It is okay to use heparin coated tubes and avoid having to use the 0.1M sodium citrate. I hope this helps. If there is anything else that I can help you with please let me know.
