Highly purified mRNA for chicken ovalbumin has been translated in a cell-free protein synthesizing system from rabbit reticulocytes in the presence or absence of EDTA-stripped microsomal membranes from dog pancreas. Nascent--but not completed--ovalbumin was transferred across the microsomal membrane, as demonstrated by cotranslational core glycosylation of ovalbumin nascent chains, by resistanc...

Ovalbumin family contains three proteins with high sequence similarity: ovalbumin, ovalbumin-related protein Y (OVAY), and ovalbumin-related protein X (OVAX). Ovalbumin is the major egg white protein with still undefined function, whereas the biological activity of OVAX and OVAY has not yet been explored. Similar to ovalbumin and OVAY, OVAX belongs to the ovalbumin serine protease inhibitor fam...

Ovalbumin, a member of the serpin superfamily, is transformed via an intermediate state into a non-cleaved, thermostabilized form (S-ovalbumin) during either the storage of unfertilized eggs or development of fertilized eggs; essentially the same thermostabilization also occurs upon in vitro incubation of isolated ovalubumin under alkaline conditions. To investigate the implications of a partia...

One proposed mechanism by which alum enhances an immune response is by its ability to induce an inflammatory response that results in the release of uric acid from necrotic cells. Uric acid is thought to be a mediator in enhancing the immune response. The aim of this study was to investigate the immunopotentiating effect of uric acid. Groups of BALB/c mice were injected intraperitoneally with o...

the immune responses of mice immunized with ovalbumin (ova) together with killed l. major (klm) promastigotes as adjuvant were studied. three doses (5 × 107, 1 × 108 and 2 × 108) of klm combined with ova (100 mg) were injected into the groups of c57bl/6 mice. bcg and complete freund’s adjuvant (cfa) were used as control adjuvants. lymphocyte proliferation and antibody titers were determined, an...

background: asthma is a chronic inflammatory disease with multifactorial and complicated mechanisms. elevated level of exhaled nitric oxide (no) in asthma and other inflammatory lung diseases has led to many studies examining no as a potential marker of airway inflammation. objective: this study was designed to determine the level of no in bronchoalveolar lavage (bal) fluid during early and lat...

The complete amino acid sequence of hen ovalbumin, comprising 385 residues, has been determined. The sequence was deduced from the 17 cyanogen bromide fragments and from peptides derived by digestion with a number of proteolytic enzymes. The molecular weight of the polypeptide chain of ovalbumin is 42699. Ovalbumin has four sites of postsynthetic modification; in addition to the acetylated N te...

BDF1 [(C57BL/6 X DBA/2)F1] mice were primed with alum-absorbed ovalbumin, and their spleen cells were cultured with ovalbumin to activate antigen-primed T cells. The activated T cells were then propagated in interleukin 2-containing medium in the presence or absence of affinity-purified glycosylation-inhibiting factor (GIF). Upon incubation with ovalbumin-pulsed macrophages, T cells propagated ...
