ITI BioChem is specialized in providing aptamer. An aptamer is a sequence of single strand nucleic acid (DNA or RNA) with a variable region of about 40 nucleotide bases, which can bind to a specific target molecule with high specificity and affinity. SELEX (systematic evolution of ligands by exponential enrichment), an elegant process by which aptamers can be generated for a given target (e.g protein), is widely used now.
The ability of DNA and RNA oligonucleotides to make strong interactions with other types of molecules, including metal ions, small molecules and large macromolecules such as proteins, nucleic acids, and cells. This range of potential targets makes them ideal for many applications，which can be used in any instance where traditionally an antibody is used, such as biomarker discovery, drug discovery, diagnostics and therapeutics.
