Extended validation for CD337 (NKp30) Antibody, anti-human, REAfinity™

Specificity

Epitope competition
In order to compare the epitope specificity of an antibody, the clone being used is compared with other known clones recognizing the same antigen in a competition assay.
Other clonesOverlap in epitope recognition with REA823
AF29-4D12++
P30-15++
Cells were incubated with an excess of purified unconjugated CD337 (NKp30) (REA823) antibody followed by staining with fluorochrome-conjugated antibodies of other known clones against the same marker. Based on the fluorescence signal obtained, the clones were identified as recognizing completely overlapping (++), partially overlapping (+), or completely different epitopes (-) of the marker.

Sensitivity

Performance comparison
Selected fluorochrome conjugated antibodies from Miltenyi Biotec were compared to commercially available hybridoma clones in flow cytometry analysis.

Flow cytometric comparison of different clones for CD337 (NKp30). Human peripheral blood mononuclear cells (PBMCs) were stained with CD337 (NKp30) antibodies and with a suitable counterstaining. As a control, CD337 (NKp30) antibody staining was omitted and cells were measured in the same channels. Flow cytometry was performed with the MACSQuant® Analyzer. Cell debris, dead cells, and cell doublets were excluded from the analysis based on scatter signals and 4',6-diamidino-2-phenylindole (DAPI) fluorescence. No FcR Blocking Reagent was used. The recommended titers of respective antibodies from different suppliers were used.

Specifications for CD337 (NKp30) Antibody, anti-human, REAfinity™

Overview

Clone REA823 recognizes the CD337 (NKp30) receptor, which is a 30 kDa type I membrane glycoprotein characterized by a single V-type Ig-like domain in the extracellular portion. CD337 is found almost exclusively on the surface of resting or activated natural killer (NK) cells and is a member of the natural cytotoxicity receptor (NCR) family which trigger cytotoxicity in NK cells. CD337 is directly involved in target cell recognition and lysis and is expressed by all resting or activated NK cells and by a small subset of T cells. Its expression density parallels that of CD336 (NKp44). It seems to be involved in killing of cells which are lysed independently from CD336 (NKp44) and CD335 (NKp46).
Additional information: Clone REA823 displays negligible binding to Fc receptors.
