Recommended Usage:

Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤ 0.25 µg per 106 cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.

CD5 is a 67 kD glycoprotein, also known as Lyt-1, Ly-1 or Ly-12. It is a member of the scavenger receptor superfamily and primarily expressed on thymocytes and mature peripheral T lymphocytes, but not on NK cells, intestinal intraepithelial gamma/delta T cells. A CD5+ B cell subset (B-1) has not been characterized in that rat.

Other Names: Ly-1, Tp67, Leu-1, T1, Lyt-1
Structure: CD5 is a 67 kD glycoprotein of scavenger receptor superfamily. It is expressed on thymocytes, T cells and small subset of B cells.
Distribution: Expressed on thymocytes, peripheral T cells, and some thymic dendritic cells. It should be noted that a CD5+ subset of B cells has not been characterized in the rat by OX-19. Most gamma/delta T cells do not express CD5.
Function: Important in T-B cell interaction.
Ligand Receptor: CD72
