The paper itself is not on this site: read it at the publisher. This page lists only the values CatLog read from it.
CatLog read 12 records (36 values) from this paper: DS-AChE (detergent-soluble acetylcholinesterase), SS-AChE (spontaneously soluble acetylcholinesterase) from Hirudo medicinalis.
Read from the paper by an AI model and checked against the paper by a second, separate AI run; code converted the units. Values are in CatLog's units; each record opens in Browse with the line the paper prints and the checks.
