摘要:
Methods are described for phototransferring a compound from a first surface to a second surface. Compounds are described with photocleavable linkers. Compounds attached to a first surface through a photocleavable linker are put in proximity (or contact) with a second surface, and then phototransferred to the second surface upon exposure to electromagnetic radiation. Illuminating the compound with radiation photocleaves the compound from the first surface and transfers the compound to the second surface.
摘要:
The present invention relates to a method for assessing the endometrium receptivity of a patient, comprising a step consisting of measuring the expression level of eleven genes in an endometrial biopsy sample obtained from said patient wherein said genes are MFAP5, ANGPTL1, PROK1, NLF2, LAMB3, BCL2L10, CD68, TRPC4, SORCS1, FST and KRT80.
摘要:
Focused libraries of vectors or genetic packages that display, display and express, or comprise a member of a diverse family of antibody peptides, polypeptides or proteins and collectively display, display and express, or comprise at least a portion of the focused diversity of the family. The libraries have length and sequence diversities that mimic that found in native human antibodies.
摘要:
The invention relates to a procedure for linking cognate pairs of VH and VL encoding sequences from a population of cells enriched in particular surface antigen markers. The linking procedure involves a multiplex molecular amplification procedure capable of linking nucleotide sequences of interest in connection with the amplification, in particular polymerase chain reaction (multiplex PCR). The method is particularly advantageous for the generation of cognate pair libraries as well as combinatorial libraries of variable region encoding sequences from immunoglobulins. The invention also relates to methods for generation of chimeric human/non-human antibodies and expression libraries generated by such methods.
摘要:
Methods for improving antibodies by a variety of DNA diversification and selection procedures are provided. Improvements include increases in affinity, alterations in specificity and effector function, as well as reduced antigenicity, e.g. humanization. Libraries of recombinant antibody sequences are provided, as are cells expressing members of such libraries. Novel phage display vectors are provided. Methods for the coevolution of an antibody and its cognate antigen are provided. Coevolution is used to evolve HIV envelope proteins with increased antigenicity and broadly neutralizing antibodies that interact therewith. Methods of improving antibodies for use in the detection of biological warfare agents are provided.
摘要:
Provided is a method and system for screening chemical compounds or compositions, wherein replicating entities are introduced into the yolk of an (un)fertilized egg or embryo. The method may be extended to elucidate the mechanism-of-action of functional chemical compounds or compositions in the same method and system. The method and system may also be employed for identifying marker genes, marker proteins or marker metabolites.
摘要:
A method of recognizing the development of an Acute Myocardial Infarction (AMI) process in an individual, wherein the method comprises steps of: profiling specific antibody reactivities or biomarkers associated with AMI susceptibility, the profiling comprises steps of: attaching a set of defined antigens to a substrate; obtaining a biological fluid derived specimen from an individual, the specimen containing a specific antibody repertoire; and binding said antibodies of the biological fluid specimen to the attached antigens thereby forming bound antibody antigen complexes; and analyzing results obtained, wherein the presence of the complexes is indicative of AMI.
摘要:
The present invention provides methods and compositions for tagging nucleic acid sequence fragments, e.g., a set of nucleic acid sequence fragments from a single genome, with one or more unique members of a collection of oligonucleotide tags, or sequence tokens, which, in turn, can be identified using a variety of readout platforms. As a general rule, a given sequence token is used once and only once in any tag sequence. In addition, the present invention also provides methods for using the sequence tokens to efficiently determine variations in nucleotide sequences in the associated nucleic acid sequence fragments.
