Abstract:
The present invention relates to a nucleic acid molecule or a polypeptide that is selected from a method that includes cell-free expression of nucleic acid molecules immobilized on a sold support system. The present invention also relates to a molecular library that has a solid support system having a plurality of nucleic acid molecules immobilized thereon.
Abstract:
The present invention provides a method of identifying a base at a target position in a single-stranded sample DNA sequence wherein an extension primer, which hybridizes to the sample DNA immediately adjacent to the target position, is provided and the sample DNA and extension primer are subjected to a polymerization reaction in the presence of a deoxynucleotide or dideoxynucleotide, whereby the deoxynucleotide or dideoxynucleotide will only become incorporated and release pyrophosphate if it is complementary to the base in the target position. Release of pyrophosphate is detected enzymatically and pyrophosphate detection enzyme(s) are included in the polymerization step.
Abstract:
A process for preparing antibodies specific for an amino acid sequence which comprises immunizing a mammal with a fused protein comprising said amino acid sequence fused to an immunogenic IgG binding protein is disclosed.
Abstract:
A method for determining whether a mammalian subject having a malignant melanoma belongs to a first or a second group, wherein the prognosis of subjects of the first group is better than the prognosis of subjects of the second group is provided. The method comprises the steps of: evaluating an amount of RBM3 protein in at least part of a sample earlier obtained from the subject and determining a sample value corresponding to the evaluated amount; comparing said sample value with a predetermined reference value; and if said sample value is higher than said reference value, concluding that the subject belongs to the first group; and if said sample value is lower than or equal to said reference value, concluding that the subject belongs to the second group.
Abstract:
The present invention provides means, such as a method, for determining whether a mammalian subject having a colorectal cancer belongs to a first or a second group, wherein the prognosis of subjects of the first group is better than the prognosis of subjects of the second group. The method comprises the steps of: evaluating an amount of RBM3 protein or RBM3 mRNA molecule in at least part of a sample earlier obtained from the subject and determining a sample value corresponding to the evaluated amount; comparing said sample value with a predetermined reference value; andif said sample value is higher than said reference value, concluding that the subject belongs to the first group; and if said sample value is lower than or equal to said reference value, concluding that the subject belongs to the second group.
Abstract:
Methods of affinity separation wherein the affinity ligand is immobilized proteinaceous ligand wherein one or more of its asparagine (Asn) residues has been modified. Methods of making a stabilized combinatorial protein by a) modification of Asn residues within a protein molecule to increase stability of the protein in alkaline conditions, and b) randomization of the protein molecule to modify its binding characteristics, and combinatorial proteins wherein in a step separate from the randomization step, the stability of the protein in alkaline conditions has been increased by modifying one or more of its Asn residues.
Abstract:
The present invention provides a method of producing an insulin C-peptide, which comprises expressing in a host cell a multimeric polypeptide comprising multiple copies of the insulin C-peptide, and cleaving the expressed polypeptide to release single copies of the insulin C-peptide. Also provided are nucleic acid molecules, expression vectors and host cells, for use in such a method and the multimeric insulin C-peptide polypeptide expressed and cleaved in such a method.
Abstract:
Tripartite recombinant DNA encoding fusion proteins which comprise three sequences, i.e., a signal peptide which is operable in a Gram positive bacterium, an immunogenic polypeptide linked thereto which is not normally expressed in a Gram positive bacterium, and a cell wall spanning and a membrane anchoring sequence, as well as their use in Gram positive bacteria to express the resultant fusion protein on their surface are described. The preferred cell wall spanning and anchoring polypeptides include Staphylococcus protein A and Streptococcus protein G.
Abstract:
The invention provides a method of identification of the base in a target position in a DNA sequence wherein sample DNA is subjected to amplification; the amplified DNA is immobilised and then subjected to strand separation, the non-immobilised strand being removed and an extension primer, which hybridises to the immobilised DNA immediately adjacent to the target position, is provided; each of four aliquots of the immobilised single stranded DNA is then subjected to a polymerase reaction in the presence of a dideoxynucleotide, each aliquot using a different dideoxynucleotide whereby only the dideoxynucleotide whereby only the dideoxynucleotide complementary to the base in the target position becomes incorpored; the four aliquots are then subjected to extension in the presence of all four deoxynucleotides, whereby in each aliquot the DNA which has not reacted with the dideoxynucleotide is extended to form double stranded DNA while the dideoxy-blocked DNA remains as non-extended DNA; followed by identification of the double stranded and/or non-extended DNA to indicate which dideoxynucleotide was incorporated and hence which base was present in the target position.
Abstract:
The present invention provides a method for determining whether a mammalian subject having a breast cancer is likely to benefit from an endocrine treatment, comprising the steps of: providing a sample earlier obtained from said subject; evaluating the amount of HMGCR protein or HMGCR mRNA present in at least part of said sample, and determining a sample value corresponding to said amount; comparing the sample value obtained in step b) with a reference value; and, if said sample value is higher than said reference value, concluding that the subject is likely to benefit from an endocrine treatment. Further, a corresponding method of treatment is provided as well as further methods uses and means which may be employed in connection with breast cancer treatment or treatment prediction.
