摘要:
The inventive anti-HGF/SF humanized antibody prepared by displaying on the surface of a phage an anti-HGF/SF chimeric Fab library comprising a set of human antibody light chain variable region (VL) and human antibody heavy chain variable region (VH) which are grafted with heavy chain complementary determining regions (HCDRs) of an anti-HGF/SF antibody of an animal other than human, has the equal or greater binding affinity than that of the parent anti-HGF/SF antibody, the neutralizing activity inhibiting the binding of HGF/SF to its receptor, cMET, while having the reduced immunogenicity in human. Therefore, the inventive anti-HGF/SF humanized antibody can be used for preventing and treating diseases effectively, e.g., cancers, by the action of binding HGF/SF to cMET.

摘要:
A bioinformatics process which provides an improved means to detect a JAK-STAT3 cellular signaling pathway in a subject, such as a human, based on the expression levels of at least three unique target genes of the JAK-STAT3 cellular signaling pathway measured in a sample. The invention includes an apparatus comprising a digital processor configured to perform such a method, a non-transitory storage medium storing instructions that are executable by a digital processing device to perform such a method, and a computer program comprising program code means for causing a digital processing device to perform such a method. Kits are also provided for measuring expression levels of unique sets of JAK-STAT3 cellular signaling pathway target genes.
摘要:
According to a first aspect of the invention, a method for the generation of a cell line is provided, comprising the steps of (a) providing a plurality of mammalian B cells, wherein each of the plurality of B cells comprises a transgenic genomic DNA sequence encoding a marker protein inserted into an endogenous immunoglobulin locus comprised in said B cell, and wherein the transgenic genomic DNA sequence is amenable to cleavage by a site directed nuclease, particularly Cas9; (b) replacing the transgenic genomic DNA sequence encoding a marker protein with a second transgenic DNA sequence encoding a protein of interest; (c) sorting B cells based on the presence or absence of the marker protein; and (d) collecting B cells in which the marker protein is absent.
摘要:
The invention provides efficient methods for combining single-substitution libraries of nucleic acids that span and encode proteins of interest and for selecting resultant mutant proteins after expression which have improved properties or characteristics.
摘要:
A general method and recombinant nucleic acid sequences, by means which the method selects a recombinant protein containing an FHA domain for binding a target molecule from a library proteins with a high-throughput method of creating protein variations within the FHA domain in non-conserved or non-structural sequences of the FHA scaffold, and the library may also be in the form of a phagemid or phage library wherein the ALP nucleic acid sequence is inserted into a vector capable of allowing the vector and expressed ALP protein from being virally packaged, and the recombinant nucleic acid sequences which are randomly mutated at varying non-conserved or non-structural FHA domain sequences.

A system for continuous mutagenesis to facilitate directed evolution, the system including DNA polymerases carrying the novel K54E point mutation, and other point mutations including I709N, A759R, D424A (herein called K54E_LF Pol I) and this methods of use to produce and detect lines where mutagenesis is continuous and does not exhibit the usual decline in mutagenesis with sequential cloning.
摘要:
Methods and compositions are provided for producing libraries of soluble random polypeptides. In the methods, the fraction of hydrophilic residues in the polypeptide is controlled so as to maintain the solubility of the polypeptide constructs.
摘要:
The invention describes a method for isolating one or more genetic elements encoding a gene product having a desired activity, comprising of the steps of: (a) compartmentalizing genetic elements into microcapsules; (b) expressing the genetic elements to produce their respective gene products within the microcapsules; (c) sorting the genetic elements which produce the gene product having a desired activity. The invention enables the in vitro evolution of nucleic acids by repeated mutagenesis and iterative applications of the method of the invention.
