摘要:
The present invention provides a cell culture medium formulation that supports the in vitro cultivation, particularly in suspension, of mammalian cells, particularly epithelial cells and fibroblast cells, and methods for cultivating mammalian cells in suspension in vitro using these media. The media comprise a basal medium and a polyanionic or polyanionic compound, preferably a polysulfonated or polysulfated compound, and more preferably dextran sulfate. The present invention also provides chemically defined, protein-free eukaryotic cell culture media comprising an iron chelate and zinc, which is capable of supporting the growth (and particularly the high-density growth of mammalian cells) in suspension culture, increasing the level of expression of recombinant protein in cultured cells, and/or increasing virus production in cultured cells.
摘要:
The present invention provides serum-free cell culture media formulations which are capable of supporting the in vitro cultivation of animal cells. The media comprise at least one nutrient of non-animal derivation, such as at least one plant peptide and/or at least one non-animal or plant lipid and/or fatty acid. The media may further optionally comprise an enzymatic digest or extract of yeast cells. The present invention also provides methods of cultivating animal cells in vitro using these cell culture media formulations. In addition, the media of the present invention can be used for growth of animal cells for virus production.

A hydraulic bushing having at least two chambers and at least one channel connecting the chambers. The bushing is made of a high durometer rubber or other polymer to increase durability. The bushing further includes a center bearing press fit in the center of the annular bushing. The bushing is further press fit into an annular seal operable to seal the fluid within the chambers and channels. The bearing, bushing, and seal assembly is then press fit into a bracket which is subsequently mounted to the vehicle. The center bearing is operable to hold the prop shaft wherein the center bearing is free to rotate within the bushing thereby allowing the prop shaft to rotate.

A masking circuit for selectively masking scan chain inputs and/or outputs during scan testing of an integrated circuit, comprises a mask register having at least two mask register elements for each scan chain to provide a plurality of masking modes; and an input and output mask control circuit for each scan chain, each mask control circuit being connected between a test pattern source and a signature register and between a serial input and a serial output of an associated scan chain and being responsive to mask control data stored in the register elements for configuring the associated scan chain in one of the plurality of masking modes during a scan test of the circuit.

This invention provides methods for detecting cancers and for evaluating the prognosis of cancer patients. In particular, the methods of this invention utilize YKL-40 as a marker for the presence or absence of a cancer and for the prognosis (e.g. likelihood of recurrence) of a cancer. Elevated levels of YKL-40 are indicative of the presence of a cancer in undiagnosed subjects and indicate likely recurrence of the cancer in subjects diagnosed as having a cancer.
摘要:
A method is disclosed for using aqueous VES-based gravel carrier fluids in gravel packing operations using screens and shunt tubes that have been run into a well completed with an oil-based mud. With this method, the previously necessary but undesirable steps of first running in a perforated liner and then displacing the oil-based mud with an aqueous-based fluid in the region to be gravel packed are both avoided while the advantages of gravel packing with an aqueous-based fluid are retained.

An embedded test, chip design utility is an ease-of-use utility for assisting a circuit designer in quickly implementing a circuit embedded test design flow. Using the utility, a designer transforms a design netlist to include embedded test structures. The utility automatically builds a workspace containing a predetermined repository structure and design environment, generates control files for executing design automation tools that operate within the design flow, and encapsulates the data so as to be self-contained and easily transferable to other design teams.
