Alginate matrix‐supported acetylcholinesterase

Abstract

A natural matrix‐supported acetylcholinesterase was prepared from alginate extracted from a green algae commonly found in Egyptian fisheries. The COO− ions of alginate‐entrapped acetylcholinesterase protein molecules forming the basic groups. Calcium ions fixed to the anionic groups contributed to preserving the activity of acetylcholinesterase when stored for long periods of time. The effects of thermal denaturation and of various organophosphorus inhibitors upon the matrix‐supported enzyme have been determined. In all cases the supported enzyme appeared to be less affected by the inhibitor than was the free enzyme.

Determination of Trace Amount of Pd(II) and Ni(II) with Newly Synthesized Pyrozlon Azo Bromo Phenol by Spectrophotometric Methods

“…Azo pyrazole derivatives and its metal complexes can be used as inkjet, they have got fastness properties for dying papers 12 and process high dying power on fibers 13 . They can also be used in subtractive photographic process and for the production of color transparences and color pictures 14 and have many applications 15 . Various methods for the assay of nickel(II) have been reported.…”
