CD15 Monoclonal Antibody (HI98), PE, eBioscience™, Invitrogen™

Description

• Description: The HI98 monoclonal antibody reacts with human CD15, Lewis X
• This 3-fucosyl-N-acetyllactosamine carbohydrate moiety is expressed by granulocytes
• Monocytes express this structure at varying degree while lymphocytes are negative
• Applications Reported: This HI98 antibody has been reported for use in flow cytometric analysis
• Applications Tested: This HI98 antibody has been pre-titrated and tested by flow cytometric analysis of normal human peripheral blood cells
• This can be used at 5 μL (0.125 μg) per test
• A test is defined as the amount (μg) of antibody that will stain a cell sample in a final volume of 100 μL
• Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test
• Excitation: 488-561 nm; Emission: 578 nm; Laser: Blue Laser, Green Laser, Yellow-Green Laser
• Filtration: 0.2 μm post-manufacturing filtered
• CD15 (Lewis X, Le(x); stage specific embryonic antigen-1, SSEA-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 tumour 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.
