title: [Comparison between human and rat erythrocyte acetylcholinesterase].
abstract: This paper reports on a comparative study of acetylcholinesterase (AChE) extracted from human and rat erythrocytic membranes. The recovery of enzymatic activity when AChE wa solubilized by means of freezing and thawing followed by treatment with 0,5% Triton X-100, represented approximately 95% of the total erythricytic activity for both human and rat preparations. When subjected to gel electrophoresis, the AChE preparation gave rice to two tipes of isoenzimatic patterns: with a single band and two bands (termed band I and band II according to their anodic migration).
