摘要:
The invention relates to a process for the hydroformylation of propylene with carbon monoxide and hydrogen to selectively form iso-butanal with respect to n-butanal, the process implementing a hydroformylation catalyst in combination with a phosphine, the hydroformylation catalyst comprising a palladium catalyst which comprises the element PdX 2 , where X is a halogen element selected from iodine I and bromine Br, the phosphine is of the form the phosphine is of the form P(R)(R')(R"), where R, R' and R" each comprise an alkyl group or an aryl group or an alkoxy group or an amino group.
摘要:
The present invention relates to a method for tightly temporally controlling the biological activity of a protein of interest in a vertebrate, upon induction of the activity of a fusion protein comprising said protein of interest and an ERM polypeptide containing a mutated ligand binding domain of the human oestrogen receptor α, with a synthetic ligand that does not interfere with oestrogen signalling. In particular, the present invention concerns a method for generating tightly temporally-controlled targeted somatic mutations in a vertebrate, preferably a mouse, by inducing the activity of a fusion protein comprising a site- specific recombinase protein and an ERM polypeptide, with a synthetic ligand devoid of oestrogenic and anti-oestrogenic activities.
摘要:
The invention relates to novel fluorescent compounds derived from non-fluorinated dipyrromethene-boron, to a method for preparing same and to the use thereof for the fluorescent marking of biological molecules. The invention also relates to biological molecules marked with said fluorescent compounds, and to the use thereof in detection methods such as medical diagnosis methods. More particularly, the detection methods of the invention are particularly useful for diagnosing neurodegenerative diseases such as Alzheimer's disease.
摘要:
The invention relates to a photocatalyst that comprises a β-SiC cellular foam and a photocatalytically active phase directly deposited on said cellular foam or on an intermediate phase deposited on said cellular foam. The average size of the cells is 2500 μm to 5000 μm. The foam may comprise nanotubes or nanofibres (particularly of carbon, SiC, and TiO 2 ) that consist of, or carry as an intermediate phase, a photocatalytically active phase.
摘要:
The invention relates to a method for manipulating, isolating, detecting or amplifying a target nucleic acid in a sample by hybridization with an oligonucleotide-oligocation conjugate, comprising allowing said nucleic acid to react with an oligonucleotide- oligocation conjugate comprising at least A1 and Bj linked together directly or via a linker, wherein. A, is an i-mer oligonucleotides, with i = 3 to 50, where Ai is an oligomer with naturally or non naturally occurring nucleobases and/or pentafuranosyl groups and/or native phosphodiester bonds, optionally comprising a marker group. Bj is a j-mer organic oligocation moiety, with j = 1 to 50, where B is - HPO3-R1-(NH-R2)n-NH-R3-O-, where R1, R2 and R3 are lower alkylene, identical or different, NH-R2 moieties being identical or different when n is >1; HPO3-R1-CH(X)-R3-O-, where Ri and R3, identical or different, are lower alkylene and X is putrescine, spermidine or spermine residue.
