Product Background

CD22, also known as Siglec-2 (sialic acid-binding immunoglobulin-type lectin 2), is a transmembrane glycoprotein belonging to the Siglec family. CD22 contains an extracellular region with immunoglobulin (Ig) domains that bind sialic acid residues, a transmembrane domain, and a cytoplasmic tail with immunoreceptor tyrosine-based inhibitory motifs (ITIMs). CD22 binds to sialic acid-containing glycoproteins, both on the same cell (cis ligands) and neighboring cells (trans ligands), influencing its clustering and activity.

Product Description

Epratuzumab is a recombinant,  humanized monoclonal antibody directed against CD22,  a cell surface glycoprotein present on mature B-cells and on many types of malignant B-cells. It binds with high specificity to normal B-cells and B-cell tumors at the third Ig-like domain of CD22. After binding to CD22,  epratuzumab's predominant antitumor activity appears to be mediated through antibody-dependent cellular cytotoxicity .

Mechanism of Action

Epratuzumab is a monoclonal antibody targeting CD22,  a molecule expressed on B cells.

Metabolism

Epratuzumab has a long half-life typical of monoclonal antibodies. Its pharmacokinetics involve distribution into the bloodstream and tissues.
