Construction of electrochemical aptasensor of carcinoembryonic antigen based on toehold-aided DNA recycling signal amplification. RenZhang,Bioelectrochemistry,2020

Applications: As control proteins
Review: To verify the specificity of the sensor for CEA detection, control experiments were carried out by using BSA, PSA, CD86 and EpCAM as control proteins. As shown in Fig. 4C, an obvious current was obtained in buffer containing CEA while only negligible currents were obtained in control groups containing BSA, PSA, CD86 and EpCAM even at a 10-fold concentration of CEA, indicating the specificity of the sensor.
PMID: 32120323

Target Data

Function Receptor involved in the costimulatory signal essential for T-lymphocyte proliferation and interleukin-2 production, by binding CD28 or CTLA-4. May play a critical role in the early events of T-cell activation and costimulation of naive T-cells, such as deciding between immunity and anergy that is made by T-cells within 24 hours after activation. Isoform 2 interferes with the formation of CD86 clusters, and thus acts as a negative regulator of T-cell activation.; FUNCTION
