Positive inotropic effects of Tityus cambridgei and T. serrulatus scorpion venoms on skeletal muscle
Comparative Biochemistry and Physiology Part C: Toxicology & Pharmacology, 2009Toxins that block voltage-dependent K+ channels and those that modify Na+ channel gating exhibit positive inotropic effect on skeletal muscle. We compared the effect of the venom of Tityus cambridgei (Tc) and Tityus serrulatus (Ts) scorpions on mouse diaphragm force, in vitro.

Purification and partial characterization of a second toxin from the scorpion Tityus serrulatus
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 19761. 1. A purification procedure is described for a second toxin of T. serrulatus, which also can be used with advantage for toxin I. 2. 2. Aminoacid compositions of toxins I and II were determined. 3. 3. Molecular weight of the toxins, were 6400 and 7700, respectively for toxins I and II. 4. 4.

Potassium channel blockers from the venom of the Brazilian scorpion Tityus serrulatus ( )
Toxicon, 2016Potassium (K(+)) channels are trans-membrane proteins, which play a key role in cellular excitability and signal transduction pathways. Scorpion toxins blocking the ion-conducting pore from the external side have been invaluable probes to elucidate the structural, functional, and physio-pathological characteristics of these ion channels.

Exploring high molecular weight components in Tityus serrulatus venom
ToxiconOur study identified high-molecular-weight compounds from Tityus serrulatus venom (TsV), and most of them have not yet been well explored. TsV was fractionated using FPLC system with different columns, analyzed by SDS-PAGE, and characterized by MALDI-TOF/TOF.

Technetium-99m labeling of tityustoxin and venom from the scorpion Tityus serrulatus
Applied Radiation and Isotopes, 2002The tityustoxin, the most toxic fraction from scorpion Tityus serrulatus venom, has been used as a tool in several neurochemical and neuropharmacological studies. Biological activities of labeled and unlabeled tityustoxin and venom were compared. The samples were labeled in the presence of stannous chloride and sodium borohydride with a yield of 60-70%

Isolation of a Bradykinin-Potentiating Factor from Scorpion Tityus Serrulatus Venom
1992A bradykinin-potentiating factor was isolated and characterized from the scorpion Tityus serrulatus venom by chromatographic techniques and reverse phase followed by biological assays. This factor showed to be able to potentiate the contractile activity of the isolated guinea-pig ileum, inhibited the angiotensin-converting enzyme and potentiated the ...
