Comparison of cystatin, lysozyme and Anti-trypsin agents activities in geese egg white
The objective of the study was to examine the activity of different biologically active proteins in geese egg whites. The experiment was performed in 8 replicates on eggs collected from Italian White geese, Polish wild geese (Gegawa) and their cross line. Analyses of activities of cystatin, lysozyme and serine proteinases inhibitors in fresh geese egg whites were carried out. Moreover, trypsin ...
متن کاملEgg White Proteins
Egg white as a protein system possesses much interest, both biochemical and technological. Study of the egg white proteins has been handicapped by the difficulty of preparation. The five variant system developed by Cohn and coworkers for the fractionation of plasma offers many advantages over the salting-out techniques (1). Low temperatures are employed to improve protein stability. Since low s...
متن کاملEgg white injury.
A 66-year-old man was admitted to our Department for a sudden loss of consciousness, tonic–clonic movement and psychomotor agitation. During the previous 4 months the patient had complained of drowsiness, fatigue, lack of appetite, and nausea. During the prior 2 months he had experienced hair loss, coating of the tongue, and skin flaking with pruritus. Two hours prior to admission, the patient ...
متن کاملCystatin, a protein inhibitor of cysteine proteinases. Improved purification from egg white, characterization, and detection in chicken serum.
The protein from chicken egg white that inhibits cysteine proteinases, and has been named 'cystatin', was purified by ovomucin precipitation, affinity chromatography on carboxymethylpapain-Sepharose and chromatofocusing. The final purification step separated two major forms of the protein (pI 6.5 and 5.6), with a total recovery of about 20% from egg white. By use of affinity chromatography and ...
متن کاملOvoglycoprotein, a protein of hen's-egg white.
1. A description is given of the isolation of a glycoprotein from hen's-egg white; it has been called ovoglycoprotein. 2. It contains 13.6% of hexose, 13.8% of hexosamine and 3% of sialic acid. 3. Hexose occurs as mannose and galactose in the ratio 2:1, hexosamine as glucosamine and sialic acid as N-acetylneuraminic acid. 4. It has S(20,w) 2.47s and a minimum molecular weight, calculated from t...
