Description
The 5B5 monoclonal antibody specifically binds to human CD77, a small neutral glycosphingolipid also referred to as globotriaosylceramide (Gb3), Burkitt 's lymphoma associated antigen (BLA), ceramide trihexoside (CTH), and Pk blood group antigen. CD77 is expressed on a subset of germinal center B-lymphocytes including centroblasts that are found with greater frequency in tonsil and mucosal lymphoid tissues and less frequently in peripheral blood, bone marrow and spleen. It has been described as a receptor for Shiga Toxin, produced by Shigella dysenteriae, and Verotoxin 1 (VT1), produced by some strains of E. coli. CD19 has been reported as a ligand for CD77. This interaction may function in adhesion and signal transduction at a specific stage of B cell differentiation. Studies have shown that cross-linking CD77 induces apoptosis in some B cell lines.
Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated to Alexa Fluor® 647 under optimum conditions, and unreacted Alexa Fluor® 647 was removed.
1. This reagent has been pre-diluted for use at the recommended Volume per Test. We typically use 1 × 10^6 cells in a 100-µl experimental sample (a test).
2. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
3. An isotype control should be used at the same concentration as the antibody of interest.

5. The Alexa Fluor®, Pacific Blue™, and Cascade Blue® dye antibody conjugates in this product are sold under license from Molecular Probes, Inc. for research use only, excluding use in combination with microarrays, or as analyte specific reagents. The Alexa Fluor® dyes (except for Alexa Fluor® 430), Pacific Blue™ dye, and Cascade Blue® dye are covered by pending and issued patents.

7. Alexa Fluor® 647 fluorochrome emission is collected at the same instrument settings as for allophycocyanin (APC).
8. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
