Isotype

Mouse IgM

Specificity

The antibody MEM-131 reacts with CD99R, an extracellular epitope restricted to a subset of CD99 molecule expressed on myeloid cells, NK cells and T lymphocytes.

Workshop

HLDA V: WS Code AS S020; HLDA V: WS Code T T-E2.02; HLDA V: WS Code T T-017

Application

FC (QC tested)

Application details

Flow cytometry: The reagent is designed for analysis of human blood cells using 20 μl reagent / 100 μl of whole blood or 10⁶ cells in a suspension. The content of a vial (2 ml) is sufficient for 100 tests.

Reactivity

Human

Antigen description

CD99 (E2, MIC2) is a transmembrane glycoprotein that is involved in regulation of T cell addhesive properties and programmed cell death distinct from typical apoptosis course. CD99 roles are specific to certain stages of T cell differentiation such as corticothymocytes. CD99R isoform expression is restricted in the haematopoietic system to T, NK and myeloid cells.

Anti-human CD99R PE antibody (clone MEM-131) works in flow cytometry application.

Analysis of the antibody staining profile was performed on blood leukocytes isolated from buffy coats. HCDM CDMaps standardized procedures (Kuzilkova D et al. Front Immunol. 2022;13:827898) were used for cell isolation and surface staining of blood leukocytes, with the modification of staining protocol using cytometry test tubes.
Mouse monoclonal anti-human CD99R PE antibody (clone MEM-131) was used in concentration 1 µg/ml in stained blood sample (2 x 10⁶ cells).

Expression profiling on peripheral blood subsets using Anti-human CD99R PE antibody (clone MEM-131). Adaptive panel

HCDM CDMaps standardized procedures (Kuzilkova D et al. Front Immunol. 2022;13:827898) were used for cell isolation and surface staining of blood leukocytes, with the modification of staining protocol using cytometry test tubes.
Suspension of blood leukocytes isolated from buffy coats (2 x 10⁶ cells) was added to the mixture of anti-human CD99R PE antibody (clone MEM-131, 1 µg/ml in stained blood sample) and Monocyte Blocking Buffer (#ED7747), vortexed and incubated for 20 min. Next, optimized backbone antibody panel (HLDA Adaptive) was added to test tubes, vortexed and incubated for 20 min. The residual erythrocytes were lysed with 2 ml of 10× diluted EXCELLYSE Easy solution (#ED7066) and incubated for 10 min. Finally, samples were centrifuged (670 g, 5 min.), supernatant removed and the cell pellet was resuspended in 200 µl of PBS for acquisition.
