Product Data
Clone Name Rib 5/2
Applications FC, FN, IHC
Recommend Dilution Suitable for Immunohistochemistry (IHC); has been described to work in FACS (see Table 1).
Recommended Dilutions for IHC:
Frozen sections: 1.5 μg/ml (1/200)
Paraffin sections: does not react on routinely processed paraffin sections.
Reactivity Rat
Host Mouse
Clonality Monoclonal
Immunogen Lymphoblasts.
Specificity Recognizes a subpopulation of rat T-cells (T-lymphocytes and thymocytes, monocytes, macrophages).
Rib 5/2 detects an epitope of the CD4 53kD glycoprotein on the cell surface. It is used for the identifcation of CD4 bearing cells, mainly T-helper / inducer lymphocytes.
Rib 5/2 stains T-cell areas in the spleen and lymphnodes well. In the thymus Rib 5/2 detects cortical and medullary thymocytes. It recognises tissue macrophages and Th-cells according to the CD 4 distribution.
It can also be applied for in vivo blocking of CD4 mediated immunological reactions.
Formulation PBS, pH 7.2 containing 0.01% Thiomerosal as preservative and 10 mg/ml BSA as stabilizer.
State: Purified
State: Lyophilized purified Ig fraction.
Reconstitution Method Restore with 0.5 ml distilled water.
Concentration 0.3 mg/ml
Purification Affinity chromatography.
Conjugation Unconjugated
Storage Condition Store the antibody at 2-8°C for one month or (in aliquots) at -20°C for longer.
Do not freeze working dilutions
Avoid repeated freezing and thawing.
Gene Name Cd4 molecule
Background CD4 is a single chain transmembraneous glycoprotein (59 kDa) which belongs to the immunoglobulin superfamily. CD4 is present on a subset of T lymphocytes ("helper/inducer" T cells) and is also expressed at a lower level on monocytes, tissue macrophages and granulocytes. The antigen is involved in binding to MHC class II molecules. The intracellular domain of the antigen is associated with p56lck protein tyrosine kinase.
Synonyms T-cell surface antigen T4/Leu-3
