• PubMed Abstract: 
  

  Although the basic scorpion K(+) channel toxins (KTxs) are well-known pharmacological tools and potential drug candidates, characterization the acidic KTxs still has the great significance for their potential selectivity towards different K(+) channel subtypes. Unfortunately, research on the acidic KTxs has been ignored for several years and progressed slowly.
