background: the use of igys in a variety of methods in different areas of research, diagnostics, medical application and biotechnology should be considered widely. objectives: development of antibodies against extra cellular domain of influenza m2 (m2e) protein in egg yolk of laying hens. methods: a fusion construct harboring c-terminal of bovine heat shock protein 70 (hsp70) and influenza m2e ...
In Argentina Bovine Genital Campylobacteriosis is routinely diagnosed by direct immunofluorescence test. Generally, the hyperimmune sera used for this test are obtained from rabbits and less often from goats. In this work, a chicken egg yolk immunoglobulin (IgY) extract was conjugated and its ability to detect campylobacters with the regular conjugate prepared with rabbit sera was comparatively...
A two-step chromatographic procedure was developed for the isolation and purification of hen IgY antibodies from egg yolk. The antibodies were completely separated from vitellin and lipids by hydrophobic interaction chromatography followed by gel filtration. Almost no residual yolk proteins, no immunoglobulin aggregates, and no antibody fragments could be detected in the final extract. Moreover...
Avian eggs contain a variety of maternally-derived substances that can influence the development and performance of offspring. The levels of these egg compounds vary in relation to environmental and genetic factors, but little is known about whether there are correlative links between maternal substances in the egg underlying common and different pathways of maternal effects. In the present stu...
one of the most important goals for increasing recognition and treatment revenue is transmitting vital data to medical care team, more quickly. nowadays, use of new technologies for transmitting data will deploy more and more daily. in this article, for transmitting electrocardiogram, first we code the signal into a suite of codes, then we will use bluetooth technology to transmit data from off...
The protective effect of hyperimmune IgY fraction of egg yolk prepared from hens hyperimmunized with multiple species of Eimeria oocysts on experimental coccidiosis was evaluated in young broilers. Chickens were continuously fed from hatch with a standard diet containing hyperimmune IgY egg yolk powder or a nonsupplemented control diet and orally challenged at d 7 posthatch with 5.0 x 10(3) spo...

A study was conducted to develop a simple sequential separation protocol to separate phosvitin and IgY from egg yolk without using organic solvents. Egg yolk was diluted with 2 volumes of distilled water (DW), homogenized, and centrifuged. The precipitant was collected and homogenized with 4 volumes of 10% NaCl (wt/vol) in 0.05 N NaOH solution to extract phosvitin. The pH of the homogenate was ...
