An aptamer affinity column for purification and enrichment of aflatoxin B1 and aflatoxin B2 in agro-products
We have developed an aptamer affinity column (AAC) for the purification and enrichment of trace aflatoxin B1 (AFB1) and aflatoxin B2 (AFB2) in genuine agro-products through the covalent conjugation of amino modif...

Affinity capture of aflatoxin B1 and B2 by aptamer-functionalized magnetic agarose microspheres prior to their determination by HPLC
A novel adsorbent is described for magnetic solid-phase extraction (MSPE) of the aflatoxins AFB1 and AFB2 (AFBs). Magnetic agarose microspheres (MAMs) were functionalized with an aptamer to bind the AFBs which th...

An oligosorbent-based aptamer affinity column for selective extraction of aflatoxin B2 prior to HPLC with fluorometric detection
The article describes an aptamer affinity column for selective solid-phase extraction of aflatoxin B2 (AFB2). Amino-modified aptamer against AFB2 was immobilized on CNBr-activated Sepharose through a covalent bon...

Visual and microplate detection of aflatoxin B2 based on NaCl-induced aggregation of aptamer-modified gold nanoparticles
We describe a fast and sensitive method for the detection of aflatoxin B2 (AFB2) that is based on the addition of AFB2-sensitive aptamers to a colloidal solution of gold nanoparticles (AuNPs). Subsequent addit...

Ectopic expression of foxtail millet zip-like gene, SiPf40, in transgenic rice plants causes a pleiotropic phenotype affecting tillering, vascular distribution and root development
Plant architecture determines grain production in rice (Oryza sativa) and is affected by important agronomic traits such as tillering, plant height, and panicle morphology. Many key genes involved in controlling ...

Ribosomal DNA gene and phylogenetic relationships of Diplura and lower Hexapods
The monophyly of Diplura and its phylogenetic relationship with other hexapods are important for understanding the phylogeny of Hexapoda. The complete 18SrRNAgene and partial 28SrRNA gene (D3-D5 region) from 2...

Phylogeny of higher taxa of hexapoda according to 12sRNA sequences
The phylogenetic relationship of Hexapoda has been debated for a long time, which will be resolved mainly depending on the settlement of monophyly, affinities and interrelationships among Protura, Collembola a...
