Rat Anti-Mouse CD4 (Clone GK1.5) recognizes an epitope on Mouse CD4. This monoclonal antibody was purified using multi-step affinity chromatography methods such as Protein A or G depending on the species and isotype.

Antigen Distribution:
The L3T4 antigen is expressed by the helper/inducer subset of mouse T-cells. The antigen is present on approximately 80% of thymocytes, 20% of spleen cells and 60% of lymph node cells. The expression of L3T4 correlates with class II MHC antigen reactivity on cloned T-cell lines.

CD4 (cluster of differentiation 4) is a glycoprotein expressed on the surface of T helper cells, regulatory T cells, monocytes, macrophages, and dendritic cells. CD4 interacts with class II molecules of the major histocompatibility complex (MHC) enhancing the signal for T-cell activation.1

Known Species Cross Reactivity: Ms+
Host Species
This biotinylated antibody is formulated in 0.01 M phosphate buffered saline (PBS) pH 7.4, 150 mM NaCl, 1% BSA and 0.09% sodium azide as a preservative.
Storage and Stability
This biotinylated antibody is stable when stored at 2-8°C. Do not freeze.
Reported Applications
IHC (Frozen), FC
Flow Cytometry: It is recommended to use the indirect method for signal enhancement when enumerating cells expressing CD4. A suggested method would be to stain cells expressing CD4 with 0.25 µg per 1 x 106 cells in a total staining volume of 100 µl followed by UltraAvidin™- R-phycoerythrin (R-PE) (Leinco Prod. No.: A104).
Each investigator should determine their own optimal working dilution for specific applications.
