I DENTIFICATION of the abnormal polypeptide chain of a hemoglobin ( Hb ) variant is often useful in connection with structural analyses and Chernoff and Pettit’ have recently improved on existing methods for this purpose by using starch gel electrophoresis of globin in urea barbital buffer. Izzo2 used this same buffer for electrophoresis of globin on cellulose acetate. Ohba et al.3 have propose...

The objective of this work was to study the feasibility of preparing cellulose acetate (CA) nanofibrous membranes by electrospinning with single solvent and their potential applying as affinity membrane. CA solutions in dichloromethane (DCM), formic acid, acetic acid and trifluoroacetic acid (TFA) were electrospun into nonwoven fiber membranes, respectively. The scanning electron microscope (SE...

A method of electrophoresis utilizing cellulose acetate is described wherein quantitation of serum protein fractions by densitometry is accomplished within 2 hr. of initiation of the procedure. The densitometer was found to have a linear response to amido black dye. Albumin and y-globulin demonstrated equal dye-binding characteristics. Combined with the absence of albumin trailing, this has aff...

BACKGROUND Cellulose acetate phthalate (CAP) has been used for several decades in the pharmaceutical industry for enteric film coating of oral tablets and capsules. Micronized CAP, available commercially as "Aquateric" and containing additional ingredients required for micronization, used for tablet coating from water dispersions, was shown to adsorb and inactivate the human immunodeficiency vi...

We describe here a simple, time-saving method for separating alkaline phosphatases on cellulose acetate, with a parallel detection of serum protein pattern. The staining procedure is based on a coupling reaction between the reaction product of alpha-naphthol with Fast Red Violet LB. The enzymatic reaction is done by bringing the cellulose acetate strip containing the phosphatase band into conta...

We describe a new principle of cellulose acetate electrophoresis (solid-support electrophoresis), in which cellulose acetate membranes are given a solid support, instead of being suspended as heretofore. The new technique is particularly well suited for screening procedures, because many samples can be processed economically on a single run. Also described for the first time, in conjunction wit...

This study describes the transformation of cellulose acetate filters into porous carbon structures by a facile, direct process. Filters from cigarettes were used as the source for cellulose acetate filters. Carbon was obtained by high-temperature treatment under inert conditions without extensive preparative methods. The resulting carbon materials showed structural features on different length ...
