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 TRA-1-85 monoclonal antibody (mAb) specifically binds to the high frequency blood group antigen OKa. The OKa blood group antigen is a 35-69 kDa glycoprotein also known as CD147, EMMPRIN, M6, or Basigin. The OKa group is widely expressed on most human tissues including, but not limited to kidney, peripheral blood leukocytes, liver, pancreas, colon, skin, and brain. TRA-1-85 mAb is often used to discern human cells from non-human cells in multiple applications including animal transplantation studies. During development, the purified TRA-1-85 mAb was found to detect OKa blood group antigen by western blot analysis of cellular lysates, by immunofluorescent staining of fixed cells, and by flow cytometric analysis of live cells.
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.
