The invention pertains to the synthesis, isolation, and characterization of hemiaminal for selective labeling of peptides, proteins, antibodies, and organic fragments with -C(=0) CH2NH2 and derivatives with -CH2NH2 group over -C(=0) CHRNH2 group (where R≠H). The invention also pertains to the method of single-site immobilization of proteins through N-terminus Gly on solid phase. The invention includes late-stage tagging of N-terminus Gly with an affinity tag, 19F NMR probe, and a fluorophore and a method for metal-free protein purification and isolation of analytically pure proteins.
该发明涉及半胺的合成、分离和表征,用于选择性标记肽、蛋白质、抗体和有机片段,其中含有-C(=0) CH2NH2和-C(=0) CH2NH2基团的衍生物,而不是含有-CH2NH2基团的-C(=0) CHRNH2基团(其中R≠H)。该发明还涉及通过N-末端甘氨酸在固相上进行单位点固定蛋白质的方法。该发明包括将N-末端甘氨酸进行末端标记,使用亲和标记、19F核磁共振探针和荧光团,并提供一种无金属蛋白质纯化和分离的方法,以获得分析纯度的蛋白质。
