Fetal proteins are high levels of proteins present during the fetal stage of development. Often related proteins assume similar roles after birth or in the embryo, in which case the fetal varieties are called fetal isoforms. Sometimes, the genes coding fetal isoforms occur adjacent to their adult homologues in the genome, and in those cases a locus control region often coordinates the transition from fetal to adult forms. In other cases fetal isoforms can be produced by alternate splicing using fetal exons to produce proteins that differ in only a portion of their amino acid sequence. In some situations the continuing expression of fetal forms can reveal the presence of a disease condition or serve as a treatment for diseases such as sickle cell anemia. Some well known examples include...
A sensor capable of super-sensitive and rapid detection of alpha-fetal protein and a preparation method and application thereof
PendingCN122171807AColor/spectral properties measurementsBiological testingFetuin bElectrochemiluminescence
This invention discloses an ultrasensitive and rapid sensor for detecting alpha-fetoprotein (AFP), constructed based on a sandwich immunoassay structure and the electrochemiluminescence resonance energy transfer (ECL-RET) principle. The advantages of this invention compared to existing technologies are: high sensitivity and ultra-low detection limit: This invention innovatively uses MIL-NH2-RuMOF@Pt as an energy donor, whose MOF structure can load a large amount of Ru(bpy)3. 2+ The luminescent molecule provides a strong and stable initial ECL signal; ZnO@PDA acts as the acceptor, with its absorption spectrum highly overlapping with the donor emission spectrum, and PDA modification improves biocompatibility and coupling efficiency. The highly efficient RET pair formed by these two molecules, combined with the sandwich immunoamplification effect, achieves efficient signal quenching, resulting in a detection limit as low as 1.1 × 10⁻⁶. ‑ 14 mg·mL⁻¹; wide linear range; excellent specificity and accuracy; good stability and repeatability; broad application prospects.
