P-Selectin Protein, Mouse (HEK293, Fc)

P-selectin is a Ca(2+)-dependent receptor on myeloid cells that specifically binds to carbohydrates on neutrophils and monocytes.It mediates interactions between activated endothelial cells or platelets and leukocytes by recognizing sialic acid-Lewis X.P-Selectin Protein, Mouse (HEK293, Fc) is the recombinant mouse-derived P-Selectin protein, expressed by HEK293 , with C-hFc labeled tag.

The P-selectin protein is a Ca(2+)-dependent receptor found on myeloid cells, which specifically binds to carbohydrates on neutrophils and monocytes. It plays a crucial role in mediating the interaction between activated endothelial cells or platelets and leukocytes. The ligand recognized by P-selectin is sialyl-Lewis X. P-selectin facilitates the rapid rolling of leukocytes over vascular surfaces during the initial stages of inflammation by interacting with SELPLG. It also interacts with SNX17. Moreover, P-selectin interacts with SELPLG/PSGL1 and PODXL2, promoting neutrophil adhesion and leukocyte rolling. This interaction requires the presence of the sialyl-Lewis X epitope on SELPLG and PODXL2, as well as specific tyrosine sulfation on SELPLG.

Measured by the ability of the immobilized protein to support the adhesion of U937 human histiocytic lymphoma cells. The ED₅₀ this effect is 5.013 μg/mL, corresponding to a specific activity is 199.48 units/mg.

  ≥ 95%, as determined by reducing SDS-PAGE.

Lyophilized powder.

Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
