  • Title: The blocking effects of omega-conotoxin on Ca current in bovine chromaffin cells.
    Author: Hans M, Illes P, Takeda K.
    Journal: Neurosci Lett; 1990 Jun 22; 114(1):63-8. PubMed ID: 2166262.
    Abstract:
    The effects of omega-conotoxin (omega-CgTX) on voltage-sensitive Ca currents (ICa) were studied in cultured bovine adrenal chromaffin cells. A maximal block of ICa of 40-50% was obtained with omega-CgTX in the microM range, and was independent of the holding potential. The onset of block was both concentration- and time-dependent. In bovine chromaffin cells, Ca channels, both sensitive and insensitive to omega-CgTX, appear to be present.
