Title: Methods for isolating and characterizing endogenous mrna-protein (mrnp) complexes
Inventor: KEENE JACK D
IPC: C12Q1/6809
Filed: 2000-12-28
Abstract: Cellular mRNA-protein (mRNP) complexes are partitioned in vivo by contacting a biological sample with at least one ligand that specifically binds at least one component of a mRNP complex.  Suitable biological samples comprise at least one mRNA-protein (mRNP) complex and include cell cultures, cell extracts, and whole tissue, including tumor tissue. Ligands include antibodies that specifically bind RNA-binding or RNA-associated proteins present in the mRNP complex. The mRNP complex is separated by binding the ligand with a binding molecule specific for the ligand, where the binding molecule is attached to a solid support. The mRNP complex is collected by removing the mRNP complex from the solid support. After collecting the mRNP  complex, the mRNA bound within the complex may be characterized and identified. Subsets of the total mRNA population of a cell may accordingly be characterized, and a gene expression profile of the cell obtained.

Abstract: A system 10 for the remote delivery of grease to a downhole end of a drill string 24 includes a cylinder 12 having a first axial end 14, a second axial end 16 and at least one bleed hole 18 extending transversely through the cylinder 12 through which water can flow. The system 10 includes a piston 20 slidably retained within the cylinder 12. A storage volume 22 is defined in the cylinder 12 between the piston 20 and the second axial end 16 for holding the grease. With the system10 lowered into the drill string 24 and placed marginally above a toe 28 of a bore hole 30, water is pumped into the drill string 24. The water flows into the second axial end 14 of the cylinder 12 pushing the piston 20 in a downhole direction. This causes the grease to be ejected from the second axial end 16 to flow about the outside of the drill string 24. A portion of the water is also bled from hole 18 to flow between the outside of the cylinder 12 and the inside of the drill string 24 to flush any grease that may otherwise flow into the drill string 24.
