Spider venoms are biologically active substances which affect a variety of vital physiological functions in both insects and mammals. The major constituents of spider venoms are protein, polypeptide and polyamine neurotoxins, enzymes, nucleic acids, free amino acids, monoamines and inorganic salts. The identification of the proteins in spider venoms is an essential step for identification of venom. In this study, we compared with protein profiles of Agelena labyrinthica venom obtained by electrostimulation of the prosoma and extracted directly from gland. There were seven components identified in whole venom, when whole venom and venom gland extracts composition of A. labyrinthica were compared by SDS-PAGE.
