摘要:
The present invention discloses an affinity-binding assay comprising a particle having at least four copies of a target molecule and at least two binding molecules specific for said target molecule, wherein a first of said binding molecules is associated with a first label and a second of said binding molecules is associated with a second label, wherein a particle having said first label and a particle having said second label are distinguishable from a particle having both said first and said second label, wherein said first and said second binding molecule each comprise at least two binding regions specific for said target molecule. The present invention also discloses a composition comprising a first binding molecule associated with a first label and a second binding molecule associated with a second label, wherein the signal obtained from said first label and said second label is distinguishable from the combined signal of said first and second label, characterised in that said first and said second binding molecule each comprise at least two binding regions specific for essentially the same target molecule, preferably for essentially the same epitope on said target molecule and a method for selecting a synthetic antigen from a collection of at least three antigens comprising using the disclosed composition and method. The invention further discloses an antigen obtainable by above described method and capable of inducing an early immune response, a kit of parts to perform said method, the use of antigens selected by said methods for use as a vaccine, and the use of antibodies and antigens as a medicament.
摘要:
Method for magnetic resonance imaging (MRI) of at least one specific element, wherein signal of background tissue represented in an MR image is at least partially dephased by applying a gradient imbalance or additional gradient, wherein signal around said element is accordingly conserved, resulting in a selective depiction of said element.
摘要:
The invention provides a novel method of analysing the proteome of a cell. The method allows the correlation of expression of proteins with the activity of compartments in the cell and the association of thus far unidentified proteins with(in) such compartments. This gives the artisan a powerful tool in the elucidation of the function of proteins thus identified. According to this method a new family of proteins was identified and the function thereof determined and confirmed by experiments. The family termed smERp belongs to the oxidoreductase proteins, but is distinct therefrom in their activity and internal structure. The invention further identifies several other proteins and their function, together with methods wherein the identified proteins can be manipulated to obtain, or gain further functionality. The invention also provides methods wherein proteins identified in the present invention are used for the production of proteins of interest.
摘要:
The present invention relates to a method for preparing Lipid II, which method comprises the steps of preparing a mixture of bacterial membranes, uridine diphosphate N-acetylmuramyl peptide (UDP-MurNAc), uridine diphosphate N-acetylglucosamine (GlcNAc), a chain of n prenyl residues, wherein n is at least 2, and optionally a detergent in a buffer; reacting the mixture thus obtained to prepare an n-Lipid II containing mixture, wherein n represents the amount of prenyl residues in the Lipid II molecule and wherein n is at least 2; and optionally further purifying the n-Lipid II containing mixture. Preferably n is selected from the range 2-25. Instead of bacterial membranes the reaction mixture may comprise isolated enzymes, such as MraY (undecaprenyl phosphate phospho-N-acetylmuramoyl-pentapeptide transferase).
