This protocol describes the generation of a fraction enriched in lysosomes from rat liver. The lysosomes are rapidly isolated using density-gradient centrifugation with gradient media that retain the osmolarity of the lysosomes such that they are functional and can be used in in vitro assays.
A method of zonal centrifugation was developed which separates rat thoracic duct lymphocytes (TDL) mainly according to size. The validity of the fractionation method was supported by light microscope observations, Coulter Counter sizing, and in vivo and in vitro labeling of lymphocytes. The distributions of lysosomal acid hydrolases in TDL fractionated by zonal centrifugation are similar to the...
The series introduced by this paper reports the results of a detailed analysis of the micro-somal fraction from rat liver by density gradient centrifugation. The biochemical methods used throughout this work for the determination of monoamine oxidase, NADH cyto
Feline leukemia virus from tissue culture fluids was concentrated 100 times by continuous-flow molecular filtration. Virus concentrates retained 100% of their original infectivity. Further purification was accomplished by a single sucrose density gradient centrifugation.
Objective(s) Herpes simplex viruses (HSVs) have widespread and ubiquitous prevalence in the human population and they have received a great deal of attention due to the range of diseases, they caused as a result of an infection. It seems that the fast and reliable diagnostic methods are needed for detecting the herpes simplex virus type 1 (HSV1) antibodies especially in patients with HSV encep...
A method of evaluating the iodine distribution in thryroglobulin has been developed. It is based on the increase in density that occurs when iodine is incorporated into proteins. Resolution of iodinated species is obtained by equilibrium centrifugation in a 34.5% (w/w) RbCl density gradient (isopycnic centrifugation) in either the analytical or preparative ultracentrifuge. The equilibrium in 34...
