High‐affinity binders for the C‐reactive protein (CRP), with dissociation constants in the pM to nM range and selectivities in human serum comparable to those of antibodies, were obtained by conjugation of 16 designed polypeptides to phosphocholine, a small molecule that binds CRP with a KD value of 5 μM (see picture). The polypeptides were not designed specifically to recognize CRP and bind by an
C反应蛋白(CRP)的高亲和力结合剂通过将16种设计的多肽与小分子磷酸胆碱结合获得,其解离常数在p M至n M范围内,并且在人血清中的选择性与抗体相当。结合CRP的K D 值为5μM(见图)。没有专门设计多肽识别CRP并通过适应的拟合机制进行结合。
