Compositions and methods for the detection of Taenia solium and the diagnosis of T. solium infection are described. The nucleotide and amino acid sequences of the antigenic T. solium polypeptides gp50a, gp50b and gp50c are provided. The compositions contain synthetic antigenic polypeptides of larval origin prepared using the sequences described herein. Probes and primers for the detection or amplification of T. solium nucleic acid molecules are also described. The polypeptides can be administered to a human or animal to protect against T. solium infection. In addition, the polypeptides are useful as research tools for studying T. solium and as reagents in assays for the detection of T. solium antibodies in a biological sample. The methods are sensitive and specific assays that utilize the stable recombinant or synthetic antigenic polypeptides or nucleic acid molecules encoding the larval polypeptides.
摘要:
The present invention solves the three-dimensional structure of BPI and thereby provides atomic coordinates of BPI from the analysis of x-ray diffraction patterns of sufficiently high resolution for three-dimensional structure determination of the protein, as well as methods for rational drug design, based on using amino acid sequence data and/or x-ray diffraction data provided on computer readable media, as analyzed on a computer system having suitable computer algorithms; and atomic coordinates are provided yielding structural information on related proteins, including the lipid binding and lipid transport protein family that includes BPI, LBP, CETP and PLTP.
摘要:
The present invention provides antibodies that specifically bind RSP-2 proteins which are involved in the cytoadhesion of P. falciparum during ring-stage infection of erythrocytes as well as methods of using these antibodies.
摘要:
An apparatus and method for penetrating a bacteria detection culture bottle in an aseptic manner. The apparatus includes the use of a sample bulb pre-connected to a product bag along with a sampler coupler including a needle or hollow spike. The apparatus also includes for the use of a sample bag or sample bulb and penetrating needle or hollow spike pre-connected or sterilely connected to a product container so that a sample may be taken for bacteria detection without contaminating the product in the product container.
摘要:
A microarray containing components of cell membranes and a high-throughput method for using the microarray to detect toxins and screen for other biological or chemical compounds that may block the binding of toxin molecules to targets is provided. The microarray according to the present invention provides an attractive platform for efficient study of fundamental aspects of molecular recognition at the cell surface. Specific binding pattern of a given toxin to a set of different biological membrane probes in the microarray can be employed as a nullsignaturenull to identify and detect the presence of a toxin in a sample.
摘要:
Disclosed are genes found in Streptococcus pneumoniae that are essential for survival for a wide range of bacteria. These genes are termed nullS-ylqF,null nullS-yqeG,null nullS-yybQ,null nullS-yerL,null and nullS-ysxC.null These genes and the polypeptides that they encode, as well as homologs and orthologs thereof can be used to identify antibacterial agents for treating a broad spectrum of bacterial infections.
摘要:
The present invention provides isolated polynucleotides encoding the Helicobacter bilis antigens P167 and P17Hb48 and the Helicobacter hepaticus antigen P25Hh4. The present invention further provides methods and kits for detection and diagnosis of Helicobacter infections using the polynucleotides and polypeptides described herein.
摘要:
A biosensor includes a substrate with areas of active receptive material disposed thereon. The receptive material is specific for an analyte of interest. A pattern of the active areas is defined on the substrate by an oxidizing photo-masking process.
摘要:
The epitope recognized by a mouse monoclonal antibody (MAb) to the crystalline surface layer protein (SLP) of Rickettsia typhi, SRT10, is mapped to ten amino acid residues (SRTag, TFIGAIATDT). The oligonucleotide sequence covering the epitope recognized by SRT10 is inserted to a mammalian expression vector together with multiple cloning sites. When the SRTag is fused in frame to the coding region of protein gene and expressed in bacteria or mammalian cells, the MAb SRT10 can detect the tagged protein by immunoblotting, immunocytochemistry, and immunoprecipitation.
