Evolution of Complex Target SELEX to Identify Aptamers against Mammalian Cell-Surface Antigens
The demand has increased for sophisticated molecular tools with improved detection limits. Such molecules should be simple in structure, yet stable enough for clinical applications. Nucleic acid aptamers (NAAs) represent a class of molecules able to meet this demand. In particular, aptamers, a class of small nucleic acid ligands that are composed of single-stranded modified/unmodified RNA/DNA m...
متن کاملMethods To Identify Aptamers against Cell Surface Biomarkers
Aptamers are nucleic acid-based ligands identified through a process of molecular evolution named SELEX (Systematic Evolution of Ligands by Exponential enrichment). During the last 10-15 years, numerous aptamers have been developed specifically against targets present on or associated with the surface of human cells or infectious pathogens such as viruses, bacteria, fungi or parasites. Several ...
متن کاملDiscovering Aptamers by Cell-SELEX against Human Soluble Growth Factors Ectopically Expressed on Yeast Cell Surface
SELEX, the process of selecting aptamers, is often hampered by the difficulty of preparing target molecules in their native forms and by a lack of a simple yet quantitative assay for monitoring enrichment and affinity of reactive aptamers. In this study, we sought to discover DNA aptamers against human serum markers for potential therapeutic and diagnostic applications. To circumvent soluble ex...
متن کاملIdentification of malaria parasite-infected red blood cell surface aptamers by inertial microfluidic SELEX (I-SELEX)
Plasmodium falciparum malaria parasites invade and remodel human red blood cells (RBCs) by trafficking parasite-synthesized proteins to the RBC surface. While these proteins mediate interactions with host cells that contribute to disease pathogenesis, the infected RBC surface proteome remains poorly characterized. Here we use a novel strategy (I-SELEX) to discover high affinity aptamers that se...
متن کاملExpression of S and pre s2 Hepatitis B Surface Antigens in Mammalian Cos-7 Cell Line
Hepatitis B virus (HBV) is a serious global health problem. The development of a safe and effective vaccinewould help infection prevention. Previous hepatitis B vaccine production involved the isolation of the noninfectious particle from chronic HBV carriers. DNA recombinant technology has been used for vaccineproduction without having been contaminated with blood-born infectious ag...
