Product Overview

Description: Human nicotinamide phosphoribosyltransferase (NAMPT) ELISA kit-Quantitative competitive is an ELISA-based in vitro research tool designed specifically for the quantitative detection of NAMPT in human samples with a range of 1.56-100 ng/mL and a minimum detectable dose (sensitivity) of 0.78 ng/mL. The kit is highly sensitive and easy to use.

Assay Principle: The ELISA analytical biochemical technique is based on NAMPT antibody-NAMPT antigen interactions (immunosorbency) and an HRP colorimetric detection system to detect NAMPT antigen targets in samples.

Background: NAMPT is the rate-limiting enzyme for nicotinamide adenine dinucleotide (NAD⁺) synthesis, catalyzing the conversion of nicotinamide to nicotinamide mononucleotide (NMN), which is then used to synthesize NAD⁺. NAMPT exists in two forms: the intracellular isoform (iNAMPT), which maintains intracellular NAD⁺ pools, and the secreted isoform (eNAMPT or Visfatin). The relevance of NAMPT to obesity research lies in NAD⁺ serving as a key cofactor for metabolic signaling and enzyme activity (e.g., Sirtuins). NAMPT activity serves as a central node linking nutritional status, energy metabolism, and aging. The secreted form of eNAMPT functions as an adipokine; studies have identified its abnormal expression in adipose tissue and serum of obese patients, suggesting potential roles in regulating insulin sensitivity and chronic inflammation.
