Isolation and partial characterization of a myotoxin from the venom of the snake Bothrops nummifer
(1986)
A myotoxin from the venom of the snake Bothrops nummifer was purified to homogeneity by ion-exchange chromatography on CM-Sephadex. The toxin is a basic dimer with a subunit molecular weight of 16,000, as estimated by ...
Purification and characterization of BaH4, a hemorrhagic metalloproteinase from the venom of the snake Bothrops asper
(2000-01)
A hemorrhagic metalloproteinase, named BaH4, was isolated from the venom of the snake Bothrops asper by a combination of ion-exchange chromatography on DEAE-Sepharose and gel filtration on Sephacryl S-200. BaH4 is a 69 kDa ...
Pitfalls to avoid when using phage display for snake toxins
(2017-02)
Antivenoms against bites and stings from snakes, spiders, and scorpions are associated with immunological side effects and high cost of production, since these therapies are still derived from the serum of hyper-immunized ...
Antivenoms for the treatment of snakebite envenomings: The road ahead
(2011-05)
The parenteral administration of antivenoms is the cornerstone of snakebite envenoming therapy. Efforts are made to ensure that antivenoms of adequate efficacy and safety are available world-wide. We address the main issues ...
Serum antibody response to polysaccharides in children with recurrent respiratory tract infections
(2001)
We evaluated children (15-months old and older) with recurrent upper respiratory tract infections and normal
levels of immunoglobulins in serum for specific polysaccharide immunodeficiency using an enzyme-linked
immunosorbent ...
p-Bromophenacyl bromide modification of Bothrops asper myotoxin II, a lysine-49 phospholipase A2, affects its pharmacological activities
(1993-09)
Modification of Bothrops asper myotoxin II, a lysine-49 phospholipase A2 variant, was carried out with p-bromophenacyl bromide. Modified toxin did not show changes in its charge and immunological properties but two of its ...
Pathological alterations induced by neuwiedase, a metalloproteinase isolated from Bothrops neuwiedi snake venom
(2001-06)
The pathological alterations induced by neuwiedase, a 22 kDa class P-I metalloproteinase from the venom of the South American pit viper Bothrops neuwiedi, were studied in mice. Neuwiedase was devoid of hemorrhagic activity ...
Cross-recognition of a pit viper (Crotalinae) polyspecific antivenom explored through high-density peptide microarray epitope mapping
(2017-07)
Snakebite antivenom is a 120 years old invention based on polyclonal mixtures of antibodies
purified from the blood of hyper-immunized animals. Knowledge on antibody recognition
sites (epitopes) on snake venom proteins ...
Preclinical evaluation of the efficacy of antivenoms for snakebite envenoming: State-of-the-art and challenges ahead
(2017-05)
Animal-derived antivenoms constitute the mainstay in the therapy of snakebite envenoming. The efficacy of antivenoms to neutralize toxicity of medically-relevant snake venoms has to be demonstrated through meticulous ...
Neutralization of four Peruvian Bothrops sp. snake venoms by polyvalent antivenoms produced in Perú and Costa Rica: preclinical assessment
(2005-06)
Envenomations after bites inflicted by snakes of the genus Bothrops constitute a public health hazard in Perú, and the intravenous administration of equine-derived antivenoms represents the only scientifically validated ...
