Product Description
Plant alkaloid that arrests the cell cycle in G2/M phase by blocking mitotic spindle formation. Depolymerizes microtubules and blocks binding of tubulin to microtubule proteins. Induces apoptosis. Triggers Raf-1 activation, phosphorylation of Bcl-2 family proteins and induction of p53 expression.

Product Description

Mitochondrial uncoupler that depolarizes the mitochondrial membrane potential, reduces cellular ATP levels, activates 5‘-AMP-activated protein kinase (AMPK) and affects mitochondrial production of reactive oxygen species (ROS). Potent activator of multiple Ca2+-sensitive K+ channels. Blocks several kinases and non-kinase proteins in vitro. Has been widely-used as a selective inhibitor of protein kinase Cδ (PKCδ). However, recent studies indicate that rottlerin has no direct effect on PKCδ and that it should not be used to determine the involvement of PKCδ in biological processes.

Product Description
Analog of microcystin-LR (Prod. No. ALX-350-012) with Trp substituted in place of Arg. Hydrophobic and believed to be more cell permeable than other microcystins. May prove useful in biochemical studies in intact cells. Microcystin-LW has a characteristically different absorption spectrum compared to other microcystins, making it a useful reference compound for HPLC analysis. The Trp confers an absorption maximum at 222nm, whereas most microcystins have a characteristic maximum at 239nm.
