Mouse Soluble E-selectin

Updated: 2026-07-15

Overview

Mouse Soluble E-selectin (sE-selectin) is a cleaved form of the transmembrane glycoprotein E-selectin, released during endothelial cell activation. It plays a critical role in leukocyte recruitment during inflammatory responses. As a research reagent, it is widely used to study vascular inflammation, atherosclerosis, and sepsis. In B2B contexts, sE-selectin is primarily supplied to pharmaceutical companies and academic laboratories. Commercial products are typically recombinant proteins produced in mammalian expression systems, ensuring proper glycosylation and biological activity.

Physical and Chemical Properties

Mouse sE-selectin is a glycoprotein with a molecular weight of approximately 110-140 kDa in its glycosylated form. The protein consists of an N-terminal lectin domain, an epidermal growth factor (EGF)-like domain, and multiple complement regulatory protein repeats. It retains ligand-binding capability to sialyl-Lewis X carbohydrates. The lyophilized form is stable at -20°C for years but requires reconstitution in sterile buffers (e.g., PBS) before use. In solution, it should be aliquoted to avoid degradation from repeated freeze-thaw cycles. Purity is typically >90% by SDS-PAGE, with endotoxin levels <1 EU/µg.

Main Applications

In biomedical research, mouse sE-selectin serves as a biomarker for endothelial activation in disease models such as rheumatoid arthritis, inflammatory bowel disease, and ischemia-reperfusion injury. It is also used to develop ELISA kits for quantifying circulating levels in preclinical studies. Pharmaceutical companies employ sE-selectin in drug screening assays to evaluate anti-inflammatory compounds targeting leukocyte-endothelial interactions. Additionally, it is utilized in flow cytometry and cell adhesion assays to investigate mechanistic pathways in vascular biology.

Safety and Storage

Mouse sE-selectin is classified as non-hazardous under normal laboratory conditions. Standard biosafety level 1 (BSL-1) precautions apply, including gloves and lab coats. Avoid inhalation or direct contact with skin/eyes. For storage, lyophilized powder should be kept at -20°C in a desiccator. Reconstituted solutions are stable for up to 1 week at 4°C or 3 months at -80°C. Always centrifuge vials briefly before opening to prevent protein loss. Suppliers typically provide detailed handling instructions with certificates of analysis (CoA).

B2B Procurement Guide

When procuring mouse sE-selectin, prioritize suppliers with ISO 9001 certification and documented quality controls. Key specifications to verify include: biological activity (e.g., binding affinity in SPR assays), endotoxin levels, and batch-to-batch consistency. Bulk purchasers (e.g., CROs) should negotiate volume discounts for orders exceeding 1 mg. Consider requesting custom formulations (e.g., carrier-free options) for specific assay requirements. Lead times for GMP-grade material may extend to 8-12 weeks. Always review SDS and technical data sheets before purchase.
