Invitrogen™ Atrial Natriuretic Peptide (ANP) Competitive ELISA Kit

Description

The Atrial Natriuretic Peptide (ANP) Competitive ELISA quantitates ANP in human plasma,urine or cell culture medium.

Principle of the method

The Atrial Natriuretic Peptide (ANP) Competitive ELISA research-use-only kit is designed to quantitatively measure ANP present in plasma,urine,and tissue culture media samples. This kit is not recommended for serum or plasma samples without extraction. An ANP standard is provided to generate a standard curve for the assay and all samples should be read off the standard curve. Standards or diluted samples are pipetted into a clear microtiter plate coated with an antibody to capture rabbit antibodies. An ANP-peroxidase conjugate is added to the standards and samples in the wells. The binding reaction is initiated by the addition of an antibody to ANP to each well. After a 1-hour incubation the plate is washed and substrate is added. The substrate reacts with the bound ANP-peroxidase conjugate. After a short incubation,the reaction is stopped and the intensity of the generated color is detected in a microtiter plate reader capable of measuring at 450 nm.

Rigorous validation

Each manufactured lot of this ELISA kit is quality tested for criteria such as sensitivity,specificity,precision,and lot-to-lot consistency. See manual for more information on validation.

The protein encoded by this gene belongs to the natriuretic peptide family. Natriuretic peptides are implicated in the control of extracellular fluid volume and electrolyte homeostasis. This protein is synthesized as a large precursor (containing a signal peptide), which is processed to release a peptide from the N-terminus with similarity to vasoactive peptide, cardiodilatin, and another peptide from the C-terminus with natriuretic-diuretic activity. Mutations in this gene have been associated with atrial fibrillation familial type 6.
