penicillin g acylase from e. coli ta1 was immobilized by cross-linked enzyme aggregates (clea), a new method for immobilization. this biocatalyst and commercial immobilized penicillin g acylase (pga-450) were used to study the effect of ph, temperature and substrate concentration on the synthesis of ampicillin from phenyl glycine methyl ester (pgme) and 6-aminopenicillanic acid (6-apa). compare...

Cascade reactions catalyzed by immobilized multi enzymatic systems are emerging as a tool to address the increasing need for green and sustainable chemistry. In this regard, carrier-free immobilization strategy of combined cross-linked enzymes aggregates (combi- CLEAs) is great interest. combi-CLEAs two or more co-immobilized into single unit where they accommodated in close proximity order min...
the aim of this study was to evaluate an enzyme - linked immunosorbent assay (elisa) for the detection of anti - helicobacter pylori (h. pylori) specific igg antibodies in specimens of oral fluid. all subjects over the age 18 years undergoing endoscopy for any reason were asked to participate in the study. two groups of 44 patients in each were selected as hp+ and hp-. at the same time, 5 milli...
