Left : IHC image of ab223052 diluted at 1 : 100 and staining in paraffin-embedded human tonsils tissue performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a Goat anti-rabbit polymer IgG labeled by HRP and visualized using 0.05% DAB. Right : Negative Control

Characterization of exosomes derived from septic mouse serum. (A) Electron microscope (EM) analysis of exosomes. The circular particles representing exosomes are indicated by arrows. The scale bar represents a length of 200 nm. (B) Exosomes containing 20 μg of proteins were used to detect exosome-specific proteins (CD9, CD63, and CD81) by Western blot. (C) The size distribution of exosomes was determined by nanoparticle tracking analysis (NTA). (D) Dynamic change in exosome protein concentrations. The exosomes were separated from 200 μl of serum harvested from septic mice at different time points for protein quantitation. (E) The sequential detection of exosomes derived from septic mouse serum. The particle sizes of exosomes were analyzed by the NTA technique. Data are shown as the mean ± SD from three independent experiments (n = 3) and analyzed by one-way ANOVA. *p < 0.05, compared with the 0 h as the control.

Target Information
CD9 also known as p24 is a member of the tetraspanin family, which includes proteins involved in various cellular processes. CD9 (p24) plays a significant role in cancer progression and metastasis by influencing cell adhesion, migration, and signaling. CD9 (p24) is found on the surface of cancer cells and within exosomes, impacting cancer progression and therapy resistance. CD9's role in cancer is complex, as it can both suppress and promote tumor growth depending on the context. The protein's interactions within tetraspanin-enriched microdomains (TEMs) are crucial for its function.

Biological function summary
The CD9 protein is integral to cell adhesion migration and fusion. It forms complexes with other tetraspanins and proteins like EWI-2 and EWI-F contributing to cellular signaling and membrane compartmentalization. Additionally CD9 plays an important role in the formation and secretion of exosomes tiny vesicles emitted by cells that mediate cell-to-cell communication. These exosomes can be analyzed using tools like exosome assays and detection kits that target CD9 proteins.
Pathways
CD9 is involved in the regulation of immune response and cell morphology. It participates in pathways such as the integrin signaling pathway and the phosphatidylinositol 3-kinase (PI3K) signaling pathway. CD9 modulates these interactions by associating with proteins such as integrins and other members of the tetraspanin family influencing cellular movement and proliferation.
