Description

Sialyl Lewis X CAS NO 98603-84-0 is a crucial carbohydrate antigen and selectin ligand involved in cell-cell recognition and adhesion processes. This compound is of significant value in biomedical research for studying inflammation, cancer metastasis, and immune cell trafficking. It is primarily needed by researchers and developers in the pharmaceutical, biotechnology, and diagnostic sectors for use as a critical standard, inhibitor, or tool compound in glycobiology and immunology studies.

Application

• Biomedical Research: As a key ligand for studying E-selectin, P-selectin, and L-selectin mediated cell adhesion and signaling pathways in inflammation and immune response.
• Oncology Research: Investigation of its role in cancer cell adhesion, extravasation, and metastasis, particularly in carcinomas.
• Drug Discovery: Serving as a target or inhibitor scaffold for developing novel anti-inflammatory and anti-metastatic therapeutic agents.
• Diagnostic Development: Utilization in the development of assays and kits for detecting inflammatory or cancer-related biomarkers.
• Glycobiology Studies: Essential standard for analytical techniques (HPLC, MS) to characterize glycosylation patterns and enzyme activities.
• Vaccine Research: Exploration as a component or target in carbohydrate-based vaccine development against cancer or pathogens.
