Extended validation for CD99R 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 REA323
HIT4 (IgM)++
MEM-131+
Cells were incubated with an excess of purified unconjugated CD99R (REA323) 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 CD99R. Human peripheral blood mononuclear cells (PBMCs) were stained with CD99R antibodies and with a suitable counterstaining. As a control, CD99R 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.

Fixation data
To provide an indication on how an antibody performs after fixation of cells, in-house data on staining results before and after fixation with 3.7% formaldehyde using Miltenyi Biotec antibodies are provided. Different experimental settings may lead to different results.

Specifications for CD99R Antibody, anti-human, REAfinity™

Overview

Clone REA323 recognizes the human CD99R antigen, an isoform of CD99 with restricted cell distribution. CD99 is a Single-pass type I membrane protein which is also known as E2 molecule or MIC2. It is involved in multiple cellular events including cell adhesion and migration, apoptosis, cell differentiation and regulation of protein trafficking either in physiological or pathological conditions. In contrast to CD99, which is broadly distributed on many cell types, CD99R is expressed only on T cells, NK cells, and monocytes but not on B cells, erythrocytes, or platelets.
Additional information: Clone REA323 displays negligible binding to Fc receptors.
