Purified Mouse Anti-Rat CD4

Immunohistochemical staining of rat CD4 + T lymphocytes. Frozen sections of normal rat spleen were stained with Purified Mouse Anti-Rat CD4 (Cat. No. 550297/554841). CD4+ T lymphocytes can be identified by the intense brown labeling of their cell surface membranes. Amplification 20X.

推奨アッセイ手順

Immunohistochemistry: Clone OX-38 is tested for immunohistochemical staining of acetone-fixed frozen sections of rat spleen or thymus. IHC of formalin-fixed paraffin embedded sections is not recommended.  This antibody has been reported to stain the CD4 subset of T lymphocytes.  The isotype control recommended for use with Purified Mouse IgG2a κ Isotype Control (Cat. No. 550339).  For optimal indirect immunohistochemical staining, the OX-38 antibody should be titrated (1:10 to 1:50 dilution) and visualized via a three-step staining procedure in combination with Biotin Rat Anti-Mouse IgG2a(Cat. No. 550332) as the secondary antibody and Streptavidin-HRP (Cat. No. 550946) together with DAB Substrate Kit (Cat. No. 550880).

  1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  2. An isotype control should be used at the same concentration as the antibody of interest.
  3. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
  4. 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.
  5. Sodium azide is a reversible inhibitor of oxidative metabolism; therefore, antibody preparations containing this preservative agent must not be used in cell cultures nor injected into animals. Sodium azide may be removed by washing stained cells or plate-bound antibody or dialyzing soluble antibody in sodium azide-free buffer. Since endotoxin may also affect the results of functional studies, we recommend the NA/LE (No Azide/Low Endotoxin) antibody format, if available, for in vitro and in vivo use.
  6. 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.

OX-38

The OX-38 antibody specifically recognizes the CD4 antigen on most thymocytes, a subpopulation of mature T lymphocytes (ie, MHC class II-restricted T cells, including most T helper cells), monocytes, macrophages, and some dendritic cells. 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. The OX-38 antibody has been reported to bind to the same epitope of CD4 as that recognized by W3/25 mAb, which is a different epitope than that recognized by OX-35 mAb. In vivo blocking of some cell-mediated immune responses by mAb OX-38 has been reported. Injection of OX-38 mAb induces allograft unresponsiveness in rats, with varying results depending on the rat strain used (high or low responder). Furthermore, in vivo depletion of CD4+ lymphocytes has been reported with this antibody.

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.
