Preparation And Storage
Product Notices
- 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).
- An isotype control should be used at the same concentration as the antibody of interest.
- 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.
- Source of all serum proteins is from USDA inspected abattoirs located in the United States.
- Pacific Blue™ is a trademark of Molecular Probes, Inc., Eugene, OR.
- Brilliant Violet™ 421 is a trademark of Sirigen.

The HECA-452 monoclonal antibody specifically reacts with Cutaneous Lymphocyte Associated Antigen (CLA), a carbohydrate domain shared by sialyl Lewis[x] (sLe[x]) and sialyl Lewis[a] (sLe[a]) antigens. It serves as a ligand for selectins including CD62E (E-selectin; ELAM-1). CLA is expressed on high endothelium and on lymphocytes including most T lymphocytes infiltrating cutaneous sites of inflammation. Amongst peripheral blood cells, it is expressed on monocytes and granulocytes and a subset of lymphocytes. The HECA-452 antibody is also reportedly crossreactive with the mouse CLA carbohydrate epitope that is transiently expressed by PSGL-1/CD162 on activated T cells. A number of studies suggest that CLA plays an important role in supporting leucocyte adhesive interactions and migration into extravascular tissues during inflammation.
The antibody was conjugated to BD Horizon™ BV421 which is part of the BD Horizon™ Brilliant Violet™ family of dyes. With an Ex Max of 407-nm and Em Max at 421-nm, BD Horizon™ BV421 can be excited by the violet laser and detected in the standard Pacific Blue™ filter set (eg, 450/50-nm filter). BD Horizon™ BV421 conjugates are very bright, often exhibiting a 10 fold improvement in brightness compared to Pacific Blue™ conjugates.
