Biotin Hamster Anti-Mouse/Rat CD81
Biotin Hamster Anti-Mouse/Rat CD81

Two-color analysis of the expression of CD81 on mouse and rat splenocytes. C57BL/6 splenocytes were simultaneously stained with FITC Rat anti-Mouse CD45R/B220 (Cat. no. 553087/553088, First and second panels) and PE Hamster IgG1 κ Isotype Control (Cat. no. 553972, First panel) or PE Hamster Anti-Mouse/Rat CD81 (Cat. No, 559519; Second panel) monoclonal antibodies. Similarly, LOU splenocytes were simultaneously stained with FITC Mouse anti-Rat CD45RA (Cat. No. 554883, Third and last panels) and PE Hamster IgG1 κ Isotype Control (Cat. no. 553972; Third panel) or PE Hamster anti-Mouse/Rat CD81 (Cat. No, 559519; Last panel) monoclonal antibodies.

Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated with biotin under optimum conditions, and unreacted biotin was removed.

Product Notices

  1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  2. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
  3. Although hamster immunoglobulin isotypes have not been well defined, BD Biosciences Pharmingen has grouped Armenian and Syrian hamster IgG monoclonal antibodies according to their reactivity with a panel of mouse anti-hamster IgG mAbs. A table of the hamster IgG groups, Reactivity of Mouse Anti-Hamster Ig mAbs, may be viewed at http://www.bdbiosciences.com/documents/hamster_chart_11x17.pdf.
  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. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
  6. An isotype control should be used at the same concentration as the antibody of interest.

Eat2

The Eat2 monoclonal antibody specifically binds to CD81, a 26-kDa nonglycosylated member of the transmembrane 4 integral membrane protein superfamily, expressed by many types of cells.  For example, CD81 participates with CD19 and CD21 in the signal  transduction complex associated with the B-cell receptor on human B lymphocytes and with the CD4 and CD8 co-receptors on human thymocytes and T lymphocytes.  In mouse fetal thymic organ culture, interactions of immature thymocytes with CD81 expressed by thymic stromal cells are required to induce development of T cells with αβ T-cell receptors.  Furthermore, CD81 has been shown to play a role in the regulation of rat mastcell degranulation.  Despite its important roles in the immune response and wide tissue distribution, CD81-deficient mice are born without obvious developmental abnormalities.  However, these mice have abnormal immune responses, and impaired fertility.  Eat2 mAb cross-reacts with the rat CD81 antigen.

Biotin
Biotin is a ubiquitous co-factor (also known as Vitamin B7) that has many properties that make it extremely useful for molecular biology. Biotin has an extremely high affinity for the Avidin family of proteins (Kd = 10-15 M), making it the perfect tool to link two molecules. Biotin labeled antibodies can be combined with any number of Avidin-conjugated probes in order to customize an assay to a particular need. This is especially useful in the case of magnetic cell separation using streptavidin/magnetic bead conjugates, or in the case of flow cytometry using streptavidin/fluorophore conjugates.
