    Rat frozen spleen section was fixed with 4% paraformaldehyde (PFA) for ten minutes at room temperature and blocked with 5% FBS for 30 minutes at room temperature. Then the section was stained with 10 µg/mL of CD4 (clone W3/25) Alexa Fluor® 488 (green), 10 µg/mL of CD8a (clone OX-8) Alexa Fluor® 647 (blue), and 10 µg/mL of purified CD38 (clone 14.27) overnight at 4°C, followed by 5 µg/mL of anti-mouse IgG2b (clone RMG2b-1) Alexa Fluor® 594 (red) for two hours at room temperature. The image was captured by 10X objective.

Description

CD4 is a 55 kD glycoprotein also known as T4. Rat CD4 is a member of the immunoglobulin superfamily and is expressed on majority of thymocytes, macrophages, and a peripheral T cell subset (T helper cells). CD4 is a T cell co-receptor that interacts with the MHC class II molecule and is involved in T cell activation.

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 million cells in 100 µl volume. For immunohistochemistry staining on frozen tissue sections, a concentration range of 2.5 - 10 µg/ml is suggested. It is recommended that the reagent be titrated for optimal performance for each application.

* Alexa Fluor® 488 has a maximum emission of 519 nm when it is excited at 488 nm.

Application Notes

The W3/25 antibody has been shown to inhibit IL-2 production by T helper cells and to prevent autoimmune T cell transfer in an MBP induced EAE model in vivo. Additional reported applications (for the relevant formats) include: immunohistochemistry of acetone-fixed frozen sections1,2, inhibition of IL-2 production3, inhibition of MBP-induced T cell activation in EAE transfer model3.
