Polyphosphate, Medium Chain (p

Product Type: Small Molecule Name: Polyphosphate, Medium Chain (p100; biotinylated) Chemical Formula: Nan+2PnO3n +1 n = the average number of phosphorus (P) atoms in the chain Molecular Weight: Heterogeneous Format: Lyophilized Purity: <1% monophosphate Buffer: 50mM MES pH 6.0, 1mM EDTA Solubility: At least 100 mM in water; <1 mM in buffers containing divalent metals (make intermediate dilutions in divalent metal ion free buffers) Concentration: When reconstituted: 1 M (phosphate monomer) NOTE: To estimate the polymer concentration, divide the phosphate monomer concentration by the modal polymer length Size Distribution: Please see vial label (lot specific) Comments: It is recommended to use ~10.2 ug of the polyphosphate to coat all wells of a streptavidin-coated 96-well plate. Storage: Dry material should be stored at room temperature (or lower) with dessication. Once reconstituted: - Stable at least 12 hours at room temperature - Stable at least 72 hours at 4C - Store long-term at -80C - Aliquot for repeated use, avoiding repeated freeze-thaw cycles - Do not store in the presence of divalent metal ions Shipped: Ambient Temperature
