Molecular characterization of allergens by recombinant DNA technology has made rapid progress in the recent few years. In the present study we immunized mice with aluminum hydroxide-adsorbed purified recombinant major timothy grass pollen allergens (rPhl p 1, rPhl p 2, rPhl p 5), dog albumin, a major animal dander allergen, and proteins with low (beta-lactoglobulin) or no (ribulose diphosphate ...

Calcium-binding proteins play essential roles in the cell. One important class of calcium-binding proteins is the annexin family. This is a family of 13 proteins, which binds to phospholipids in a calcium-dependent manner. Osteosarcoma cell line (MG-63) is a transformed cell that has many characteristics of the differentiated cell, such as a considerable serum dependency in its growth rate. Usi...

BACKGROUND The pollen coat is the first structure of the pollen to encounter the mucosal immune system upon inhalation. Prior characterizations of pollen allergens have focused on water-soluble, cytoplasmic proteins, but have overlooked much of the extracellular pollen coat. Due to washing with organic solvents when prepared, these pollen coat proteins are typically absent from commercial stand...

A panel of cDNAs encoding allergenic proteins was isolated from an Aspergillus fumigatus cDNA library displayed on the surface of filamentous phage. Solid phase-immobilized serum immunoglobulin E (IgE) from A. fumigatus-allergic individuals was used to enrich phage displaying IgE-binding molecules. One of the cDNAs encoded a 11.1-kD protein that was identified as acidic ribosomal phosphoprotein...

In Korea, common whelk (Buccinum undatum) is a popular edible shellfish. The aim of this study was to observe the sensitization rate to common whelk and to characterize its allergens. We carried out skin prick test (SPT) in 1,700 patients with various allergic diseases. Specific IgE were detected by ELISA in the patient sera and ELISA inhibition tests were conducted. IgE-binding components were...

background one disadvantage of expressing heterologous proteins in escherichia coli is that the proteins are frequently expressed as insoluble inclusion bodies. to avoid this problem, heterologous proteins are typically expressed as a fusion protein. maltose binding protein (mbp) is one of the widely used partners for production of recombinant fusion proteins in e. coli. mbp is among the most e...

Methods b-Lactoglobulin, whole casein and its four different fractions, i.e. as1-, as2-, band -caseins, were isolated from raw CM and GM. Purified b-caseins were subjected to a mild proteolysis by plasmin which generated 3 peptides, i.e. f(1-28), f(29-107) and f(108-207/9). Synthetic peptides partially recovering the N-terminal f(29107) part of the caprine b-casein were also produced. Immunorea...

Peanut allergy is a significant IgE-mediated health problem because of the increased prevalence, potential severity, and chronicity of the reaction. Following our characterization of the two peanut allergens Ara h 1 and Ara h 2, we have isolated a cDNA clone encoding a third peanut allergen, Ara h 3. The deduced amino acid sequence of Ara h 3 shows homology to 11S seed-storage proteins. The rec...

Summary House dust mites are among the most important allergy triggers worldwide. While of genus Dermatophagoides occur almost worldwide, tropical mite Blomia tropicalis and storage only importance for certain areas or groups people. The allergens pteronyssinus Der p 1, 2, 23 with immunoglobulin E (IgE)-binding frequencies more than 70% high allergenic activity. Also 5, 7, 21, which have IgE-bi...
