FAS (Fatty Acid Synthase) is a central enzyme in de novo lipogenesis (triglyceride production). It is a target for SREBP and is upregulated by LXR activation. Fatty liver is often the result of FAS activation. It is also one of the accepted markers for insulin resistance and SREBP , LXR activation.
Western Blot: Fatty Acid Synthase antibody [NB400-114] - Expression of fatty acid synthase (FAS) in the chicken hypothalamus. A: total RNA (1 ug) isolated from different tissues (brain, hypothalamus, and liver and muscle, which were chosen as positive controls) was subjected to RT-PCR using specific primers for chicken FAS (GenBank accession JO4485) or ribosomal 18S as a control (GenBank accession AF173612) B: tissue lysates (brain, hypothalmus, and liver and muscle, which were chosen as positive controls) were subjected to Western blot as described in MATERIALS AND METHODS. Blots were incubated with anti-FAS antibody and revealed by enhanced chemiluminescence. Picture compliments of Dridi S. et al, Am J Physiol Regul Integr Comp Physiol. 2006 Jul;291(1):R138-47.

Immunohistochemistry: Fatty Acid Synthase Antibody [NB400-114] - Immunohistochemical localization of FAS in chicken hypothalmus. Paraffin sections were obtained from 3-wk-old broiler chickens.
Western Blot: Fatty Acid Synthase Antibody [NB400-114] - Western blot analysis of Fatty Acid Synthase, using NB400-114. Samples: 50 ug of total mouse liver lysate.
