- Observation BSP-2 was dominated by glucose, with minor galactose, arabinose and rhamnose residues.
- Observation The number-average molecular weight of BSP-2 was 3.612 ± 0.13646 kDa.
- Observation The weight-average molecular weight of BSP-2 was 4.456 ± 0.18019 kDa.
- Observation The z-average molecular weight of BSP-2 was 6.364 ± 0.5518 kDa.
- Observation The peaked molecular weight of BSP-2 was 2.808 ± 0.09041 kDa.
- Intervention effect BSP-2 inhibited the production of IFN-γ, TNF-α and IL-1β in LPS-stimulated RAW264.7 cells.
- Mechanism The anti-inflammatory effects of BSP-2 are mediated by regulation of the NF-κβ pathway.
- Intervention effect BSP-2 downregulated p65, p-p65, IκBα, p-IκBα, COX-2 and iNOS proteins in RAW264.7 cells.
