Biological Activity

MFG-E8 is expressed in mammary epithelial cell surfaces and aortic media. MFG-E8 plays an important role in the maintenance of intestinal epithelial homeostasis and the promotion of mucosal healing. It promotes VEGF-dependent neovascularization and contributes to the phagocytic removal of apoptotic cells in many tissues. It also binds to phosphatidylserine-enriched cell surfaces in a receptor-independent manner. MFG-E8 has opsonization of the apoptotic cells and binding to integrins on the surface of phagocytic cells. It also mediates the engulfment of the dead cell.

The recombinant human MFGE8 consists of 390 amino acids and predicts a molecular mass of 44.1 kDa.


Biotin/Protein Ratio: 0.7-1 as determined by the HABA assay

Endotoxin < 1.0 EU/μg

Lyophilized from sterile 20 mM Tris, 150 mM NaCl, pH 8.5, 10 % glycerol, 0.2 M Arginine, 0.01 % Tween-20.

Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.

Recombinant Human DPP4/CD26 (Mammalian, C-6His)

DPP4/CD26 is a signal-anchor for type II membrane protein that belongs to the peptidase S9B family. DPP4/CD26 acts as a positive regulator of T-cell coactivation, by binding at least ADA, CAV1, IGF2R, and PTPRC. It’s binding to CAV1 and CARD11 induces T-cell proliferation and NF-kappa-B activation in a T-cell receptor/CD3-dependent manner.

USP14 belongs to the ubiquitin-specific processing (USP) family which is a deubiquitinating enzyme (DUB) with His and Cys domains. USP14 acts also as a physiological inhibitor of endoplasmic reticulum-associated degradation (ERAD) under the non-stressed condition by inhibiting the degradation of unfolded endoplasmic reticulum proteins via interaction with ERN1.
