Description

The monoclonal antibody 29A1.4 recognizes mouse NKp46, also known as CD335. CD335, a member of the natural cytotoxicity receptor (NCR) family, is a glycoprotein with 2 Ig-like domains and a short cytoplasmic tail. Expression of CD335 is uniquely found on NK cells (including immature NK cells (as defined as DX5- CD3-) and thereby allowing discrimination between NKT cells and NK cells (NKp46+, CD3-). Furthermore unlike many of the NK markers which also stain NKT cells, staining with 29A1.4 is not strain specific. Staining has been shown on C57Bl/6, SJL. CBA/CA and BALB/C strains. NKp46 has been shown to play a role in NK cell-mediated lysis of several tumor cells and pathogen-infected cell lines.

The 29A1.4 monoclonal antibody has been shown to activate NK cells in vitro. The 29A1.4 monoclonal antibody does not deplete NK cells in vivo.

Applications Reported

For research use only, not for diagnostic or therapeutic use. This 29A1.4 antibody has been reported for use in flow cytometric analysis.

Applications Tested

This 29A1.4 antibody has been tested by flow cytometric analysis of mouse splenocytes. This can be used at less than or equal to 1 μg per million cells in a 100 μl total staining volume. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.
