摘要:
The present invention provides non-human mammalian cell lines that are deficient in CMP-Neu5Ac hydroxylase (Cmah) and/or glycoprotein alpha-1,3-galactosyltransferase (Ggta1). Also provided are methods for using the cells disclosed herein for producing recombinant proteins with human-like patterns of glycosylation.
摘要:
The present invention relates to diionic liquid salts of dicationic or dianionic molecules, as well as solvents comprising such diionic liquids and the use of such diionic liquids as the stationary phase in a gas chromatographic column.
摘要:
The present invention provides compositions comprising a metal amidoborane and an amine, and processes for preparing the metal amidoborane compositions. In particular, the process comprises contacting ammonia borane with a metal amide in the presence of an amine solvent to form the metal amidoborane composition. The invention also provides methods for generating hydrogen, wherein the method comprises heating the metal amidoborane composition such that hydrogen is released.
摘要:
The present invention provides methods for modifying chromosomal sequences. In particular, methods are provided for using RNA-guided endonucleases or modified RNA-guided endonucleases to modify targeted chromosomal sequences.
摘要:
An organometallic precursor is provided. The precursor corresponds in structure to Formula I: Cp(R)nM(CO)2(X) (Formula I) wherein: M is Ru, Fe or Os; R is C1-C10-alkyl; X is C1-C10-alkyl; and n is 1, 2, 3, 4 or 5. The precursors are useful in chemical phase deposition processes, such as atomic layer deposition (ALD) and chemical vapor deposition (CVD).
摘要:
The present invention provides methods and kits for editing specific chromosomal sequences in cells. In particular, targeting endonucleases and single-stranded nucleic acids are used to edit the chromosomal sequence.
摘要:
This disclosure provides methods and devices for quantitating, separating and/or detecting water in a liquid, gas or solid sample comprising one or more chemicals, the method comprising: providing the liquid, gas or solid sample comprising water and the one or more chemicals; and exposing said liquid, gas or solid sample to at least one solid support including at least one dicationic and/or tricationic species of Formula I or II adsorbed, absorbed or immobilized on the solid support.
摘要:
The present invention provides compositions and methods for monitoring cellular signal transduction events. In particular, signal transduction events may be monitored by the use of biosensors comprising protein-binding domains, which bind signal-transduction proteins, and fluorescent proteins. Provided herein, therefore, methods for detecting activation of signal transduction proteins or screening for agents that modulate the activity of signal transduction proteins. Also provided are cells comprising the biosensors; lentiviral particles comprising biosensor coding sequence; and kits comprising the lentiviral particles.
