title: [Conductivity and diameter of latrotoxin channels in lipid bilayers].
abstract: It is shown that approximately 9 A Ca-selective ion channels were induced in bilayer lipid membrane (BLM) from phosphatidylserine by nonpurified spider venom (Latrodectus tredicimguttatus) and by alpha-latrotoxin obtained from it. It is established that channels greatly different in conductivity have the same diameter and nearly the same charge constitution, that evidences for their claster organization. The purification process as well as freezing-thawing and long time keeping influence the channel conductivity without changing its diameter and selectivity.
