Xanthine oxidase (XO) generates reactive oxygen species, including hydrogen peroxide (H2O2), as it oxidizes specific substrates in the presence of water and oxygen.{15324} 6-Formylpterin is an oxidized pterin produced by photolytic breakdown of folic acid.{24043} It binds to one of two active sites on XO nearly quantitatively and irreversibly and prevents the metabolism of other substrates at the second site, resulting in “hetero-substrate” inhibition at nanomolar concentrations.{24043,24041} However, 6-formylpterin itself is converted by XO to 6-carboxylpterin and H2O2 and the turnover rate of this reaction can actually be accelerated by prior binding of a hetero-substrate to XO.{24041} In this way, 6-formylpterin acts as an intracellular generator of H2O2 in cells expressing XO, altering cellular function.{24042,24039}

    SC-1 – 5 mg

    The maintenance of embryonic stem cells in culture typically requires feeder cells and various exogenous factors found in serum. Murine embryonic stem (mES) cells can be maintained in the absence of feeder cells and serum but require the leukemia inhibitor factor (LIF) and bone morphogenic protein (BMP) to prevent differentiation and promote self-renewal.

    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.
