Activation of the complement system and leukocyte recruitment by Tityus serrulatus scorpion venom

International Immunopharmacology, 2005
The scorpion Tityus serrulatus is considered one of the most dangerous species in Brazil. Its venom evokes an inflammatory response, although the exact mechanism of this effect is still unknown. The aim of the present study was to investigate the effect of Tityus serrulatus venom (TsV) on the complement system (CS) and on leukocyte recruitment ...

Purification and partial characterization of a second toxin from the scorpion Tityus serrulatus

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1976
1. 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.

Technetium-99m labeling of tityustoxin and venom from the scorpion Tityus serrulatus

Applied Radiation and Isotopes, 2002
The 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%

Exploring high molecular weight components in Tityus serrulatus venom

Toxicon
Our 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.

Isolation of a Bradykinin-Potentiating Factor from Scorpion Tityus Serrulatus Venom

1992
A 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 ...
