Purified Mouse Anti-Rat CD3

Immunohistochemical staining of T lymphocytes. The frozen section of normal rat spleen was reacted with Purified Mouse Anti-Rat CD3 (Cat. No. 550295). T lymphocytes in the periarteriolar sheath, are identified by the brown labeling of their cell surface membrane.

Preparation And Storage

Store undiluted at 4°C. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography.

Recommended Assay Procedures

Immunohistochemistry: Purified Mouse Anti-Rat CD3 (Cat. No. 550295) is recommended to test for immunohistochemical staining of acetone-fixed frozen sections and paraffin sections. Tissue tested was rat spleen. The antibody stains T lymphocytes. The isotype control recommended for use with this antibody is Purified Mouse IgG3, κ Isotype Control (Cat. No. 550341). For optimal indirect immunohistochemical staining, the G4.18 antibody should be titrated (1:10 to 1:50 dilution) and visualized via a three-step staining procedure in combination with Purified Mouse IgG3, κ Isotype Control (Cat. No. 553401) as the secondary antibody and Streptavidin HRP (Cat. No. 550946) together with the DAB Substrate Kit (Cat. No. 550880). A detailed protocol of the immunohistochemical procedure can be found at http://www.bdbiosciences.com/us/resources/s/cellbiology

Product Notices

  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. 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.
  4. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
  5. 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.
  6. 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.
  7. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.

G4.18

The G4.18 monoclonal antibody specifically recognizes the T-cell receptor-associated CD3 cell-surface antigen found on thymocytes, peripheral T lymphocytes, and dendritic epidermal T cells. It has been reported that CD3 expression is down-regulated within 24 hours in concanavalin A-stimulated rat T cells, and soluble mAb inhibits the allogeneic mixed-lymphocyte proliferative response and cell-mediated cytotoxicity to allogeneic target cells. In vivo treatment with G4.18 mAb prevents cardiac and skin allograft rejection, resulting in donor-specific tolerance. Pre-incubation of splenocytes with the alternate anti-rat CD3 monoclonal antibody, 1F4, blocks staining with mAb G4.18.

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.
