      Purified Rat Anti-Mouse CD4
      Purified Rat Anti-Mouse CD4
      Immunohistochemical staining of mouse CD4. Frozen sections of normal mouse spleen were stained with the anti-mouse CD4 antibody clone RM4-5. CD4+ T lymphocytes can be identified by the intense brown labeling of their cell surface membranes. Amplification 20X.

      Recommended Assay Procedures

      Immunohistochemistry:  Clone RM4-5 is recommended to test for immunohistochemical staining of acetone-fixed frozen or zinc-fixed paraffin embedded sections of mouse spleen or thymus.  IHC of formalin-fixed paraffin embedded sections is not recommended.  The isotype control recommended for use with this antibody is purified rat IgG2a (Cat. No. 559073). For optimal indirect immunohistochemical staining, the RM4-5 antibody should be titrated (1:10 to 1:50 dilution) and visualized via a three step staining procedure in combination with biotinylated polyclonal anti-rat Ig (Cat.No. 559286) as the secondary antibody and streptavidin-HRP (Cat.No. 550946) together with the DAB detection system (Cat.No. 550880).  More conveniently, the anti-rat Ig HRP detection kit (Cat. No. 551013) can be used which contains the biotinylated secondary antibody, the antibody diluent, Streptavidin-HRP and DAB substrates for use in the staining procedure.

      Product Notices

      1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
      2. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
      3. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
      4. This antibody has been developed for the immunohistochemistry application. However, a routine immunohistochemistry test is not performed on every lot. Researchers are encouraged to titrate the reagent for optimal performance.
      5. An isotype control should be used at the same concentration as the antibody of interest.
      6. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.

      RM4-5

      The RM4-5 monoclonal antibody specifically binds to the CD4 (L3T4) differentiation antigen expressed on most thymocytes, subpopulations of mature T lymphocytes (i.e., MHC class II-restricted T cells, including most T helper cells and immunosuppressive regulatory T cells), and a subset of NK-T cells. CD4 has also been reported to be detected on pluripotent hematopoietic stem cells, bone marrow myeloid and B-lymphocyte precursors, intrathymic lymphoid precursors, and a subset of splenic dendritic cells. CD4 has been reported to be expressed on the plasma membrane of mouse egg cells and is involved in adhesion of the egg to MHC class II-bearing sperm. CD4 is an antigen coreceptor on the T-cell surface which interacts with MHC class II molecules on antigen-presenting cells. It participates in T-cell activation through its association with the T-cell receptor complex and protein tyrosine kinase lck. Purified RM4-5 mAb has been reported to block the binding of FITC-conjugated anti-mouse CD4 clones GK1.5 and H129.19, but not the RM4-4 clone.

      Purified
      Tissue culture supernatant is purified by either protein A/G or affinity purification methods. Both methods yield antibody in solution that is free of most other soluble proteins, lipids, etc. This format provides pure antibody that is suitable for a number of downstream applications including: secondary labeling for flow cytometry or microscopy, ELISA, Western blot, etc.
