Protein aptamers The field of molecular biology and therapeutics has witnessed a significant advancement with the development of peptide aptamers. These remarkable molecules are not your typical peptides, but rather highly specific binding agents that offer a potent alternative to traditional biological tools like antibodies. Peptide aptamers are essentially small, artificial polypeptides or short amino acid chains that are engineered to exhibit specific binding affinity for a designated target molecule. Their ability to precisely recognize and interact with their targets makes them invaluable for a wide range of applications, from diagnostics to novel therapeutic strategies.Peptide Aptamers: Development and Applications

At their core, peptide aptamers are small recombinant proteins, typically composed of around 20 amino acids.Peptide aptamers as guides for small-molecule drug ... A key characteristic of these molecules is that they are often constrained within a larger protein scaffold.作者：NT Tung·2017·被引用次数：75—Thepeptide aptamer, which has an isoelectric point of 9.77, exhibits positive charge in PBS pH 4.
