Extended validation for CD57 Antibody, anti-human

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.

Cells were incubated with an excess of purified unconjugated CD57 (TB03) 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 CD57. Human peripheral blood mononuclear cells (PBMCs) were stained with CD57 antibodies and with a suitable counterstaining. As a control, CD57 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 CD57 Antibody, anti-human

Overview

Clone TB03 specifically recognizes human CD57. CD57, also known as HNK-1 or Leu-7, is an antigenic oligosaccharide moiety detected on extracellular proteins of certain cell types. In blood, CD57 is found on 15–20% of mononuclear cells, including subsets of natural killer (NK) and T cells, though not on erythrocytes, monocytes, granulocytes, or platelets. Also, CD57 expression can be found on a variety of neural cell types.
CD57 has been shown to be expressed on late stage effector CD8
+
T cells. The frequency of CD57
+
T lymphocytes is raised in a variety of diseases. CD57 expression is also increased on chronically activated CD8
+
T cells in persistent viral infections, such as HIV.
