Rat anti Mouse CD5 antibody, clone YTS 121.5.2 recognizes murine CD5 (Lyt-1) a cell surface glycoprotein expressed by T-lymphocytes.
Studies suggest that CD5 plays an important role in the regulation of immune tolerance and lymphocyte selection.
Rat anti Mouse CD5 antibody, clone YTS 121.5.2 is suitable for T-cell depletion in vivo (Cobbold et al. 1984).

Flow Cytometry Neat 1/5
Where this antibody has not been tested for use in a particular technique this does not necessarily exclude its use in such procedures. Suggested working dilutions are given as a guide only. It is recommended that the user titrates the antibody for use in their own system using appropriate negative/positive controls.
Flow Cytometry
Use 10ul of the suggested working dilution to label 106 cells in 100ul.

The Fc region of monoclonal antibodies may bind non-specifically to cells expressing low affinity fc receptors. This may be reduced by using SeroBlock FcR (BUF041A/B).
