Selectin E (SELE), recombinant human protein is supplied as a lyophilized powder. It is suitable for use in analysis of protein structure, and performing cell based assays. It can also be used as an immunogen, as a protein standard, or in other research applications.

This recombinant protein was expressed from a DNA sequence encoding the extracellular domain (Met 1-Pro 556) of the human SELE precursor(NP_000441.2) fused to the polyhistidine-tagged Fc region of human IgG1 at the C-terminus.

Activity: Measured by the ability of the immobilized protein to support the adhesion of U937 human histiocytic lymphoma cells . When cells are added to SELE coated plates (2 µg/ml, 100 µl/well) approximately 90 %-100 % will adhere specifically .

Formulation: Lyophilized in 140 mM NaCl, 2.7 mM KCl, 10 mM Na₂HPO₄, 1.8 mM KH₂PO₄, pH 7.4, 5% Mannitol, 5% Trehalose, 0.02% Tween-80.

Reconstitution: Dissolve the protein in sterile double distilled water to a concentration of 25 mg/ml or lower. It is recommended that the protein be aliquoted and be used as soon as possible. Store aliquots under sterile conditions at -20°C. Avoid repeated freeze-thaw cycles.

Expiration Date: Expires one year from date of receipt when stored as instructed.
