Activities of the chloroplasts and nucleus are coordinated by retrograde signaling, which has crucial roles in plant development and environmental adaptation. However, the connection between chloroplast status and nuclear genome stability is not well understood. Chloroplast state transitions allow the plant to balance the absorption capacity of the photosystems in an environment in which the light quality was changing.

As an important member of the Siglec family, SIGLEC-15 plays an important role in osteoclast differentiation, bone remodeling, and tumor immune evasion. In the tumor microenvironment, SIGLEC-15 functions independently of the B7-H1/PD-1 pathway. In this study, the SIGLEC-15 fusion protein (SIGLEC-15-Fc) was successfully expressed and purified using a eukaryotic expression system.

Homogeneous analysis techniques offer several advantages as alternatives to heterogeneous immunoassays, such as simplicity and rapidity. In this study, a visual homogeneous immunoassay without a labeling process was developed based on target-induced steric hindrance to regulate competitive recognition mechanism. Specifically, as the analyte concentration varies, the change of microenvironment based on steric hindrance could affect the recognition of Cu by signal probes.

Background: Estriol (E3) is a common estrogen responsible for regulating the female reproductive system, but excessive amount can pose health risks to humans and wild life. Therefore, sensitive and accurate detection of estriol level is crucial. A novel competitive ECL immunosensor based on a dual signal amplification strategy of AuNPs@GO@SmMoSe and Gd(MoO) was fabricated for ultrasensitive detection of estriol.

Hemoglobin, composed of α- and β-chains, is essential for oxygen transport and is key in diagnosing and treating gastrointestinal and blood disorders. It also aids in detecting blood contamination and estimating transfusion volumes. Immunological methods, based on antigen-antibody interactions, are distinguished by their high sensitivity and accuracy.
