Extended validation for CD105 Antibody, anti-mouse, 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 REA1058
MJ7/18++
Cells were incubated with an excess of purified unconjugated CD105 (REA1058) 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 CD105. Mouse bone marrow cells were stained with CD105 antibodies and with a suitable counterstaining. As a control, CD105 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 CD105 Antibody, anti-mouse, REAfinity™

Overview

Clone REA1058 recognizes the mouse CD105 antigen, also known as endoglin. CD105 is a proliferation-associated and hypoxia-inducible protein, abundantly expressed in angiogenic endothelial cells. In mouse bone marrow, CD105 is also expressed on a population of Sca-1
+
hematopoietic stem cells (HSCs). This population has a long-term repopulating (LTR) capacity and is therefore termed LTR-HSCs. Furthermore, on liver sinusoidal endothelial cells (LSEC), CD105 is co-expressed with CD146 (LSEC).
Additional information: Clone REA1058 displays negligible binding to Fc receptors.
