Description

The eBioBT3.1 monoclonal antibody recognizes BT3.1, BT3.2 and BT3.3. The BT family of proteins is a subgroup of the Ig superfamily (IgSF). BT is a glycoprotein that forms a major component of the milk fat globule molecule. In addition to BT, there are six other genes that have been discovered which have been sub-divided into the BT2 (BT2.1, BT2.2, and BT2.3) and BT3 (BT3.1, BT3.2, and BT3.3) families. BT3.1, BT3.2, and BT3.3 share 95% mRNA identity. BT3 molecules are constitutively expressed on the cell surface of antigen-presenting cells, and the IgV-like domain of BT3.1 is sufficient for interaction with its counter-receptor. BT3.1 is expressed by T cells, B cells and CD14+ cells.

Applications Reported

For research use only, not for diagnostic or therapeutic use. This eBioBT3.1 (20.1, BT3.1) antibody has been reported for use in flow cytometric analysis.

Applications Tested

This eBioBT3.1 (20.1, BT3.1) antibody has been tested by flow cytometric analysis of normal human peripheral blood lymphocytes. This can be used at less than or equal to 1 μg per 100 μl blood (or per 1 million cells in 100 μl total staining volume). It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.
