Immunofluorescent analysis of Visfatin in HeLa cells using a Visfatin recombinant rabbit monoclonal antibody (Product # 701090) followed by detection using an Alexa Fluor 488-conjugated goat anti-rabbit secondary antibody (green) (Image A). Nuclei were stained using DAPI (Image B) and a composite image showing actin stained with Alexa Fluor 594 phalloidin (red) (image C) showing cytoplasmic and nuclear localization of Visfatin.

ABfinity™ recombinant antibodies are rabbit monoclonal antibodies, unmatched for producing superior results. ABfinity™ antibodies are developed by immunizing animals, screening for functionality, cloning the immunogen-specific antibody genes into high-level mammalian expression vectors, produced on a large scale, and purified with Protein A.
ABfinity™ monoclonal antibodies resemble rabbit monoclonals isolated from serum or produced by hybridomas, but demonstrate greater specificity and sensitivity. Because ABfinity™ recombinant antibodies are derived from cloned DNA sequences of the heavy and light antibody chains, they are not susceptible to cell-line drift or lot-to-lot variation, thus allowing for peak specificity and performance.
Intact IgG appears on a non-reducing gel as ~150 kDa band and upon reduction generating a ~25 kDa light chain band and a ~50 kDa heavy chain.
Visfatin, also known as pre-B cell colony-enhancing factor, is an adipocytokine that is abundantly secreted by visceral adipose tissue, with insulin mimetic effects. Visfatin mimics insulin signaling by binding to the insulin receptor and reducing glucose release from liver cells, while stimulating glucose utilization in adipocytes and myocytes. Visfatin is also invoved in enhancement of cell proliferation, biosynthesis of nicotinamide mono-and dinucleotide and glucose homeostasis.
