Fc Engineered Anti-Human CD20 Therapeutic Antibody, a CDC-Enhanced Biobetter [Lot: CB20-PZ29] (CAT#: BioBet-C029ZP) Datasheet

MS4A1

membrane spanning 4-domains A1

This gene encodes a member of the membrane-spanning 4A gene family. Members of this nascent protein family are characterized by common structural features and similar intron/exon splice boundaries and display unique expression patterns among hematopoietic cells and nonlymphoid tissues. This gene encodes a B-lymphocyte surface molecule which plays a role in the development and differentiation of B-cells into plasma cells. This family member is localized to 11q12, among a cluster of family members. Alternative splicing of this gene results in two transcript variants which encode the same protein.

Protein Based Therapies
Monoclonal antibody (mAb)

Murine IgG1

Ibritumomab tiuxetan, trade name Zevalin. The drug combines the monoclonal mouse IgG1 antibody ibritumomab with the chelator tiuxetan to treat relapsed or refractory B-cell non-Hodgkin's lymphoma. Ibritumomab tiuxetan is a monoclonal antibody radioimmunotherapy that targets the CD20 antigen on the surface of B cells and malignant B lymphocytes.

Ibritumomab

Ibritumomab tiuxetan targets binding to the CD20 antigen found on the surface of normal and malignant B cells (instead of B cell precursors), thereby killing and killing B cells and some nearby cells through radiation of attached isotopes (mainly beta emission) . In addition, the antibody itself may trigger cell death through antibody-dependent cell-mediated cytotoxicity (ADCC), complement-dependent cytotoxicity (CDC), and apoptosis. These actions collectively eliminate B cells in the human body, thereby enabling lymphoid stem cells to form a new healthy B cell population.
