Gene Information

human ... CD81(975)

General description

Cluster of differentiation 81 (CD81) is expressed on the oocyte surface. It consists of five large helical segments and belongs to the tetraspanin family. The gene encoding this protein is localized on human chromosome 11p15.5.
The antibody M38 reacts with CD81, a 25 kDa member of the tetraspanin family, expressed on majority of cells.

Immunogen

MOLT-4 (human T-ALL cell line)

Application

The reagent is designed for Flow Cytometry analysis. Suggested working dilution for Flow Cytometry is 1 μg/mL of sample. Indicated dilution is recommended starting point for use of this product. Working concentrations should be determined by the investigator.

Biochem/physiol Actions

Cluster of differentiation 81 (CD81) has a role in membrane organization, cell-cell interactions, cellular fusion and protein trafficking. It is also involved in receptor clustering and signaling. CD81 is overexpressed in cancers.
