<p>Applications A cell-permeable chloro-nitro-benzamido compound that acts as a potent, specific, irreversible, and high-affinity antagonist of PPARγ with a Ki of 1 nM. Displays &gt;800-fold greater selectivity for PPARγ over PPARα and PPARδ (Ki = 0.85 µM and 1.8 µM, respectively). Blocks hormone- and agonist-induced adipogenesis in 3T3-L1 cells. It suppresses interactions between PPARγ and coactivator-derived peptides, while promotes the recruitment of corepressor-derived peptides. Shown to modulate the interaction of PPARγ2 with the cofactor proteins through covalent binding to Cys313 in its ligand-binding domain.<br>References Lee, G., et al: J. Biol.

<p>Stability Moisture Sensitive<br>Applications Succinimidyl-6-(biotinamido) Hexanoate is a biotinylation reagent incorporating an aminocaproyl “spacer”. This can reduce the steric hindrance in binding avidin to some biotinylated compounds when used to biotinylate both the antibody and the carrier in the Protein Avidin-Biotin Capture System. This system avoids the direct interaction of a captured antibody with solid surfaces, such as plastics, which may reduce antigenicity. It has also been used to enhance the detection of DNA on nitrocellulose. Has also been used as a cell surface labelling reagent<br>References Hofmann, K., et al.: Biochemistry, 21, 978 (1982); Leary, J.J., et al.: P. Natl. Acad. Sci.
