  • 製品の概要

    Abcam’s BNP 45 rat in vitro ELISA (Enzyme-Linked Immunosorbent Assay) kit is designed for the quantitative measurement of BNP 45 in plasma, serum, tissue extract, and cell culture supernatants.

    A BNP 45 specific antibody has been precoated onto 96-well plates and blocked. Standards or test samples are added to the wells and subsequently a BNP 45 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 BNP 45 captured in plate.

  • 特記事項

    There is significant cross-reactivity between BNP32 and BNP45.

  • 研究分野
  • 機能
    Cardiac hormone which may function as a paracrine antifibrotic factor in the heart. Also plays a key role in cardiovascular homeostasis through natriuresis, diuresis, vasorelaxation, and inhibition of renin and aldosterone secretion. Specifically binds and stimulates the cGMP production of the NPR1 receptor. Binds the clearance receptor NPR3.
  • 組織特異性
    Brain and also in atria, but at much lower levels than ANP.
  • 配列類似性
    Belongs to the natriuretic peptide family.

Vielen Dank für Ihren Anruf.

Wenn das Futter keinen Einfluss auf die Produktion dieser Peptide hat (wie durch zB salzreiche Nahrung), sehe ich keinen Grund, warum die Ratten fasten sollten.

Ich hoffe, dies hilft Ihnen weiter....
