Background InformationCD15 (Le(x); Lewis x or SSEA-1; stage specific embryonic antigen-1) is a trisacharide determinant (3-fucosyl-N-acetyllactosamine) expressed on several glycolipids, glycoproteins and proteoglycans of various cell types, e.g. granulocytes, mast cells, monocytes, macrophages, cells of gastric mucosa, nervous system or various tumor cells. There are several variants of Lewis x, such as sialyl-Lewis x or sulphated Lewis x. Cells with high surface expression of Le(x) antigen exhibit strong self-aggregation, based on calcium-dependent Le(x)-Le(x) interaction. This process is involved for example in embryo compaction or in autoaggregation of teratocarcinoma cells. Sialyl-Le(x) and its isomer sialyl-Le(a) are ligands of selectins. CD15 expression has been extensively used to confirm diagnosis of Hodgkin´s disease.
UsageThe reagent is designed for indirect immunofluorescence analysis by Flow Cytometry. Suggested working usage is 1·µg/ml. Indicated dilution is recommended starting point for use of this product, but working concentrations should be validated by the investigator.
Storage BufferThe reagent is provided in Tris buffered saline (TBS) solution, pH ≈8.0, containing 0.09% (w/v) sodium azide.
StorageAvoid prolonged exposure to light. Store in the dark at 2-8°C. Do not freeze.
StabilityDo not use after expiration date stamped on vial label.
