摘要:
A method is provided for selecting membrane-translocating peptides (MTPs) from a peptide display library that are capable of crossing or penetrating a lipid membrane. A plurality of nucleic acid constructs that encode displayed peptides are expressed, resulting in the formation of a plurality of nucleic acid-peptide complexes, each complex comprising at least one displayed peptide associated with the corresponding nucleic acid construct encoding the displayed peptide; the complexes are exposed to a population of membrane-encapsulated compartments, allowing a translocating reaction to occur; complexes that remain unassociated with the membrane are removed; optionally complexes that are associated with the membrane are removed; and internalised nucleic acid-peptide complexes are recovered. The membrane-encapsulated compartments may be artificial vesicles such as liposomes, or populations of one or more cell types.
摘要:
The present invention concerns methods and reagents useful in modulating transcription factor gene expression in a variety of applications, including methods of use in therapeutic, diagnostic, target validation, and genomic discovery applications. Specifically, the invention relates to small nucleic acid molecules, such as short interfering nucleic acid (siRNA), short interfering RNA (siRNA), and doublestranded RNA (dsRNA) molecules capable of mediating RNA interference (RNAi) against E2F1, NFkB, CREB-1, and/or CDC2A gene expression, useful in the treatment of cell cycle disorders, inflammatory conditions, reproductive disorders, cancers and any other condition that responds to modulation of E2F1, NFkB, CREB-1, and/or CDC2A expression and/or activity.
摘要:
A single tool T-shaped tool terminates at the bottom of its vertical portion with a first rectangular slot or socket for holding a nested and detachable socket for turning a rectangular valve lever arm engaged therein. Each of the first and second rectangular slot and socket mate with a corresponding gas and water supply valve levers wherein rotating the horizontal cross-arm of the T section opens or closes the corresponding supply line. The first and second rectangular components that define the valve lever arm engaging sockets are each marked with a different surface intended to correspond with surface marking on the supply line or valve lever to facilitate easy and rapid identification of the valve in emergencies.
