Extended validation for CD45RA 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 CD45RA (T6D11) 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.
Knockout validation
To ensure antibody specificity, the target gene is knocked out in a suitable cell line using the CRISPR/Cas9 system and the knockout is confirmed by sequencing of the target locus. The antibody is considered to bind specifically to the intended epitope if no antibody binding to the knockout cells can be detected. The antibody staining is controlled by fluorescence microscopy and/or flow cytometry.

As a control, CD45RA 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 CD45RA Antibody, anti-human

Overview

Clone T6D11 recognizes the human CD45RA antigen which is expressed on naive CD4
+
and CD8
+
T cells as well as on CD8
+
effector T cells. CD45RA is also present on subsets of B and NK cells as well as on plasmacytoid dendritic cells. The CD45RA antibody recognizes the 220 kDa isoform of the leukocyte common antigen (LCA), a transmembrane tyrosine phosphatase.
