Leukotrienes (LTs) are a group of acute inflammatory mediators derived from arachidonic acid in leukocytes. The majority of these metabolites are formed through the 5-lipoxygenase (5-LO) pathway.{11267} 14,15-LTC4 is a member of an alternate class of LTs synthesized by a pathway involving the dual actions of 15- and 12-LOs on arachidonic acid via 15-HpETE and 14,15-LTA4 intermediates.{453,391,15256,11160} 14,15-LTC4 is classified as an eoxin, because it is formed mostly by eosinophils.{15256} However, mast cells and nasal polyps can synthesize 14,15-LTC4 as well. Little is known about the physiological actions of 14,15-LTC4. It has weak contractile activity on both guinea pig ileum and pulmonary parenchyma in contrast to the effects of 5-LO-derived LTs.{11158,11187} However, in an in vitro permeability assay, 14,15-LTC4 can increase vascular permeability of human endothelial cell monolayers, with similar potency to that of 5-LO-derived LTs resulting in plasma leakage – a hallmark of inflammation.{15256}

    PtdIns-(3,4,5)-P3-biotin (sodium salt) – 50 µg

    The PtdIn phosphates play an important role in the generation and transduction of intracellular signals.{8344,4096,14518} PtdIns-(3,4,5)-P3-biotin is an affinity probe which allows the PIP3 to be detected through an interaction with the biotin ligand. This design allows PtdIns-(3,4,5)-P3-biotin to serve as a general probe for any protein with a high affinity binding interaction with inositol-(3,4,5)-triphosphate phospholipids, such as phosphatidylinositol 3-kinase, PTEN, or PH-domain-containing proteins.
