摘要：
Dimethyl-DL-2,3-disteroyloxypropyl-2'-hydroxy-ethylammonium (Rosenthal's inhibitor) was coupled to carboxyhexyl-Sepharose 4B, through carbodiimide chemistry. Phopholipase A2 from Heloderma horridum horridum and Crotalus adamanteus bind to the immobilized ligand in the presence of Ca2+ and can be easily eluted under acidic conditions or in the presence of a cheating agent, respectivley. This affinity media proved to be effective also in the purification of a Ca2+-independent phospholipase A1 from vespid venom.
