Identification of the major mannose-binding proteins from chicken egg yolk and chicken serum as immunoglobulins.
Chicken egg yolk contains a mannose-binding protein that could be purified with a modification of the procedure of affinity chromatography and gel filtration used for chicken serum mannose-binding protein. The yolk protein was indistinguishable from the serum protein with respect to apparent molecular masses (169 +/- 7 kDa), subunits (74 kDa and 27 kDa, in approximately 1:1 ratio) produced afte...
متن کاملDistribution of egg white proteins in chicken blood serum and egg yolk.
The four proteins, ovalbumin, conalbumin, lysozyme, and ovomucoid, which comprise the major portion of the proteins of chicken egg white have now been isolated. Quantitative immunochemical investigations of these proteins (l-2) have led to the development of reagents and methods suitable for the study of their distribution in the tissues of the chicken. Such a study has been carried out with eg...
متن کاملSpecific Chicken Egg Yolk Antibodies against Enterotoxigenic Escherichia coli K99 in Serum and Egg Yolk of Immunized Laying Hens
Enterotoxigenic Escherichia coli K99 is one of the dominant pathogens associated with diarrhea of calves. Immunoglobulin Y (IgY), has been used as an inexpensive alternative to antibiotics for the prevention and therapy of several bacterial infections. The study aimed to prepare IgY antibodies against E. coli K99 and to investigate its in vitro effectiveness. E. c...
متن کاملRelationship between biotin-binding proteins from chicken plasma and egg yolk.
The plasma of laying hens contains a specific biotin-binding protein that appears to be identical with an egg-yolk biotin-binding protein. Both proteins are saturated with biotin and require elevated temperatures to effect the exchange of [14C]biotin for the protein-bound vitamin. The heat-exchange curve in each case is the same and differs sharply from that of avidin, the egg-white biotin-bind...
متن کاملidentification and extraction of chicken egg yolk immunoglobulin from egg by polyethylene glycol (peg) precipitation
background : staphylococcus aureus strains exhibiting multiple antibiotic resistances are isolated from most communities and hospital infections. treatment of patients with these infections has been difficult. the aim of this study was to detect and extract, the egg yolk immunoglobulin y as a potential source of anti- s. aureus antibody. methods : specific igy was produced by immunizing hens wi...
