Scientific Data Images for Human PBEF/Visfatin Antibody

Human PBEF/Visfatin Antibody in ELISA Standard Curve.

Human PBEF/Visfatin ELISA Standard Curve.

Recombinant Human PBEF/Visfatin protein was serially diluted 2-fold and captured by Mouse Anti-Human PBEF/Visfatin Monoclonal Antibody (Catalog # MAB4335) coated on a Clear Polystyrene Microplate (Catalog # DY990). Mouse Anti-Human PBEF/Visfatin Monoclonal Antibody (Catalog # MAB43351) was biotinylated and incubated with the protein captured on the plate. Detection of the standard curve was achieved by incubating Streptavidin-HRP (Catalog # DY998) followed by Substrate Solution (Catalog # DY999) and stopping the enzymatic reaction with Stop Solution (Catalog # DY994).

Applications for Human PBEF/Visfatin Antibody

Application
Recommended Usage

ELISA

This antibody functions as an ELISA capture antibody when paired with Mouse Anti-Human PBEF/Visfatin Monoclonal Antibody (Catalog # MAB43351).

This product is intended for assay development on various assay platforms requiring antibody pairs. We recommend the Human PBEF/Visfatin DuoSet ELISA Kit (Catalog # DY4335-05) for convenient development of a sandwich ELISA.

Please Note: Optimal dilutions of this antibody should be experimentally determined.

Background: PBEF/Visfatin

PBEF (pre-B cell colony-enhancing factor), also known as visfatin and nicotinamide phosphoribosyltransferase, is an approximately 52 kDa member of the NAPRTase family of molecules. It functions both intracellularly and extracellularly, where it participates in NAD synthesis and insulin receptor activation, respectively. Human PBEF is 491 amino acids in length and contains no signal sequence. There is at least one alternative splice form that shows a 5 aa substitution for the C-terminal 128 amino acids (aa 364-491). Over aa 27-491, human PBEF shares 96%, 97%, and 96% aa identity with mouse, porcine, and canine PBEF, respectively.
