Preparation and Evaluation of Lamivudine Microspheres Using Various Cellulose Polymers

The present study was planed to prepare microspheres for sustained release of Lamivudine using various cellulose polymers such as Ethyl cellulose, Cellulose acetate phthalate, cellulose acetate by employing solvent evaporation technique. Microspheres were characterized for the particle size distribution, wall thickness by scanning electron microscopy (SEM), angle of repose, drug content, bulk d...

Ocular gene delivery systems using ternary complexes of plasmid DNA, polyethylenimine, and anionic polymers.

In this experiment, we developed anionic ternary complexes for effective and safe ocular gene delivery. Ternary complexes were constructed by coating plasmid DNA (pDNA)/polyethylenimine (PEI) complex with anionic polymers such as γ-polyglutamic acid (γ-PGA) and chondroitin sulfate (CS). The cationic pDNA/PEI complex showed high gene expression on the human retinal pigment epithelial cell line, ...

Human gamma globulin fractionation on anion exchange cellulose columns.

The serum proteins designated as y-globulins include all proteins of the slowest moving of the several major protein groups seen on serum electrophoresis conducted at alkaline pH (2). Among the y-globulins of normal serum are proteins of differing electrophoretic mobility (3,4), proteins with sedimentation coefficients of 6.6 S and 18 S in the ultracentrifuge (2, 3, 5, 6)) many individual antib...
