Crystallization of chicken egg white lysozyme from assorted sulfate salts
Chicken egg white lysozyme has been found to crystallize from ammonium, sodium, potassium, rubidium, magnesium, and manganese sulfates at acidic and basic pH, with protein concentrations from 60 to 190 mg/ml. Crystals have also been grown at 4°C in the absence of any other added salts using isoionic lysozyme which was titrated to pH 4.6 with dilute sulfuric acid. Four different crystal forms ha...
متن کاملSeparation of ovotransferrin and ovomucoid from chicken egg white.
Ovotransferrin and ovomucoid were separated using 2 methods after extracting the ovotransferrin- and ovomucoid-containing fraction from egg white. Diluted egg white (2×) was added to Fe(3+) and treated with 43% ethanol (final concentration). After centrifugation, the supernatant was collected and treated with either a high-level ethanol (61% final concentration) or an acidic salt combination (2...

متن کاملThe effect of florfenicol egg-injection on embryonated chicken egg
Pathogens are an important and significant hazard for human and animal health. In recent years, antibiotics are used to treat different types of infection caused by bacterial agents. In veterinary medicine, antibiotics injected into hatching eggs to eliminate pathogens and prevention of egg transmission of disease, but the adverse effects of drugs have always been a major conc...
