Screening and Preparation of Nanobodies for SIGLEC-15 Detection.

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.

[Seasonal variations and driving factors of phytoplankton community shift in Datun Lake with long-term stress of arsenic contamination.].

Heavy metal is an important environmental stress that threatens water quality and ecological health of surface waters. Therefore, it is vital to identify the responses of lake community to long-term pollution for sustainable ecological restoration of polluted lakes. From June 2017 to March 2018, we conducted a seasonal survey of phytoplankton and environmental factors in Datun Lake, which had a decadal history of tailing-related arsenic contamination.
