The antibody was conjugated with Alexa Fluor® 647 under optimal conditions, and is at >85% purity. The solution is free of unconjugated Alexa Fluor® 647.
Storage & Handling:
The antibody solution should be stored undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.
Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For immunofluorescent staining, the suggested use of this reagent is 5 µl per million cells or 5 µl per 100 µl of whole blood. It is recommended that the reagent be titrated for optimal performance for each application.
* Alexa Fluor® 647 has a maximum emission of 668 nm when it is excited at 633nm / 635nm. ** Alexa Fluor® is a registered trademark of Molecular Probes, Inc.

The TRA-1-81 antibody reacts with a 200-240 kD cell surface antigen expressed by human embryonic stem cells (ESC), embryonic germ cells (EG), and embryonal carcinoma cells. The expression of TRA-1-81 on human ESC is downregulated upon differentiation. Further studies have shown that TRA-1-81 is neuroaminidase-resistant carbohydrate epitope expressed on podocalyxin, a member of mucin-like glycoprotein with CD34 family. Podocalyxin is a type I tranmembrane sialoprotein with anti-adhesion property.
Other Names:
Podocalyxin
Structure:
Mucin-like protein, CD34 family member, 200-240 kD
