Isotype

Mouse IgM

Specificity

The antibody MEM-195 reacts with CD173 (H2), an extracellular saccharide antigen expressed mainly during early hematopoiesis; it is also expressed on endothelial cells.

Workshop

HLDA VII

Application

FC (QC tested)

Application details

Flow cytometry: The reagent is designed for analysis of human blood cells using 10 μl reagent / 100 μl of whole blood or 10⁶ cells in a suspension. The content of a vial (1 ml) is sufficient for 100 tests.

Reactivity

Human

Immunogen

Human thrombocytes

Preparation

Purified antibody is conjugated with R-phycoerythrin (PE) under optimum conditions. Unconjugated antibody and free fluorochrome are removed by size-exclusion chromatography.

Antigen description

CD173 (blood group antigen H2) is a fucosylated saccharide (Fuc-alpha-1-2-Gal-beta-1-4-GlcNAc-beta) generated by beta-D-galactoside 2-alpha-L-fucosyltransferase (FUT1). CD173 belongs to markers of early hematopoiesis; it is expressed mainly on CD34-positive hematopoietic progenitor cells. CD173 is a precursor structure of CD174 (Lewis Y) and is also structurally related to CD15 (Lewis X). On endothelial cells CD173 and CD174 are concentrated on pseudopodial extensions responsible for initial contacts between endothelial cells.
