Proteomic and biological characterization of the venom of the redtail coral snake, Micrurus mipartitus (Elapidae), from Colombia and Costa Rica
(2011-12)Venoms of the redtail coral snake Micrurus mipartitus from Colombia and Costa Rica were analyzed by “venomics”, a proteomic strategy to determine their composition. Proteins were separated by RP-HPLC, followed by SDS-PAGE, ... -
Proteomic and functional analysis of the venom of Porthidium lansbergii lansbergii (Lansberg’s hognose viper) from the Atlantic Department of Colombia
(2015)The venom of the Lansberg's hognose pitviper, Porthidium lansbergii lansbergii, a species found in the northern region of Colombia, is poorly known. Aiming to increase knowledge on Porthidium species venoms, its proteomic ... -
Proteomic and functional profiling of the venom of Bothrops ayerbei from Cauca, Colombia, reveals striking interspecific variation with Bothrops asper venom
(Journal of Proteomics Volume 96, 16 January 2014, Pages 159–172, 2014-01)Bothrops ayerbei, a pitviper inhabiting the Patía River's basin (Valle Alto del Río Patía) in the Southwestern Department of Cauca, Colombia, was considered as a variant form of Bothrops asper prior to being proposed as a ... -
Proteomic and toxicological analysis of the venom of Micrurus yatesi and its neutralization by an antivenom
(2022)Coralsnakes belong to the family Elapidae and possess venoms which are lethal to humans and can be grouped based on the predominance of either three finger toxins (3FTxs) or phospholipases A2 (PLA2s). A proteomic and ... -
Proteomic and toxicological characterization of the venoms of the most enigmatic group of rattlesnakes: The long-tailed rattlesnakes
(2022)The most enigmatic group of rattlesnakes is the long-tailed rattlesnake group, consisting of three species: Crotalus ericsmithi, Crotalus lannomi and Crotalus stejnegeri. These species have been the least studied rattlesnakes ... -
Proteomic and toxicological profiling of the venom of Bothrocophias campbelli, a pitviper species from Ecuador and Colombia
(Toxicon 90, 2014)Detailed snake venom proteomes for nearly a hundred species in different pitviper genera have accumulated using ‘venomics’ methodologies. However, venom composition for some lineages remains poorly known. Bothrocophias ... -
Proteomic and toxinological characterization of the venom of the South African Ringhals cobra Hemachatus haemachatus
(2018-06)The protein composition and toxinological profile of the venom of the African spitting elapid Hemachatus haemachatus (Ringhals) were characterized by bottom-up proteomics and functional in vitro and in vivo assays. Venom ... -
