Browsing Sobre-expresión de ciclofilinas en el parásito unicelular Trypanosoma cruzi: Desarrollo de herramientas para el análisis de la función de proteínas. by Subject "low-abundance proteins"
Protein samples can be challenging to analyze due to the presence of high-abundance proteins masking low abundance proteins of interest, such as biomarkers and novel physiological mediators. Cyclophilins are chaperones
involved in the cis/trans isomerization of peptidyl-prolyl bonds in peptides or proteins and have been found in every
organism sequenced to date. Although considerable progress has been made in the characterization of some
cyclophilins expressed in diverse parasites invading humans, the main aspects of low-abundance members of this
family remain unknown. In the present work, we present that the combined strategy of using more specific antibodies
and increasing the presence of subcellular proteins in the sample, allowed us to confirm the expression of a 21.1 kDa
cyclophilin for the first time in Trypanosoma cruzi.
