Detection of PBEF/Visfatin in 3T3‑L1 Mouse Cell Line by Flow Cytometry. 3T3-L1 mouse embryonic fibroblast adipose-like cell line was stained with Rat Anti-Human/Mouse PBEF/ Visfatin Monoclonal Antibody (Catalog # MAB4044, filled histogram) or isotype control antibody (Catalog # MAB006, open histogram), followed by Allophycocyanin-conjugated Anti-Rat IgG F(ab')₂Secondary Antibody (Catalog # F0113). To facilitate intracellular staining, cells were fixed with paraformaldehyde and permeabilized with saponin.

Background: PBEF/Visfatin

PBEF, also called Nampt or visfatin, is a ubiquitous 52 kDa nicotinamide phosphoribosyltransferase. It is the rate-limiting component in the biosynthesis of NAD⁺, and functions in the cytoplasm to regulate energy metabolism during stress responses and immune activation. Although it lacks a signal sequence, PBEF appears to be secreted by visceral adipose tissue and functions as a noncompetitive insulin mimetic. Mouse PBEF shows 96% and > 99% aa identity with human and rat PBEF, respectively.
