          DescriptionFormalin-fixed and heat-killed Staphylococcus aureus cells bearing protein A that bind to the Fc portion of human IgG subclasses 1, 2, and 4, and to IgG from other species (binding capacity: ≥2 mg human IgG/100 mg cells). Used for many purposes, including radioimmunoassays, enzyme immunoassays, agglutination, and immunoprecipitation of antigens. PANSORBIN® also stimulates B-lymphocyte production and inhibits neoplasm growth. Lyophilized from preparations of Cat. No. 507858. Note: size of 5 g or 1 g refers to the wet cell weight.

          Recommended reaction conditions
          The procedures used for performing immunoprecipitations using PANSORBIN® cells are somewhat variable, but this protocol can serve as a general guideline. PANSORBIN® cells work best when the antibody is human (IgG1, IgG2, IgG4), rabbit IgG (all isotypes), or mouse (IgG2a, IgG2b, IgG3). Prewashing: 1. Transfer desired amount of PANSORBIN® cells to a microfuge tube (typically 10-30 µl of a 10% PANSORBIN® cell suspension per immunoprecipitation). 2. Centrifuge at 3000 x g for 5 min, or at maximum speed in a microfuge for 1 min at 4°C. 3. Aspirate the supernatant. 4. Resuspend to the original volume or in 1.0 ml of cold lysis buffer, whichever is greater. Mix gently. 5. Repeat wash (steps 2-4). 6. Resuspend the final pellet to the original volume (from step 1) in lysis buffer. 7. If kept sterile, washed PANSORBIN® cells are stable at 4°C. Pre-Clearing (Optional): Pre-clearing with PANSORBIN® cells prior to immunoprecipitation removes material that binds nonspecifically, reducing the background. 1. Add 10-30 µl of washed PANSORBIN® cells to the lysate prior to incubation with the primary antibody. 2. Incubate for 1 h on ice, mixing occasionally. 3. Centrifuge at 3000 x g for 5 min, or at maximum speed in a microfuge for 1 min at 4°C. 4. Transfer the supernatant to another microfuge tube and discard the pellet. Alternatively, the lysate can be pre-cleared with PANSORBIN® cells which have been pre-bound to nonspecific antiserum (see Secondary Antibody pre-binding procedure). Primary Antibody: 1. Add the required amount of primary antibody to the lysate. 2. Incubate for at least 1 h on ice, mixing occasionally. 3. If a secondary antibody step is not required or desired, proceed to the PANSORBIN® Step described below. Secondary Antibody: In some cases, a secondary antibody will be necessary. For example, if the primary antibody is mouse IgG1, it is best to use a rabbit anti-mouse IgG as a secondary antibody. If desired, the secondary antibody can be pre-bound to the PANSORBIN® cells to eliminate the loss of antibody-antigen complexes which have not bound to the protein A. 1. Incubate the desired amount of secondary antibody with prewashed PANSORBIN® cells for 45-60 min on ice. 2. Centrifuge at 3000 x g for 5 min, or at maximum speed in a microfuge for 1 min at 4°C. 3. Aspirate the supernatant and wash the lysis buffer. 4. Resuspend in lysis buffer to a volume equal to the original volume of PANSORBIN® cells which were added. Alternatively, the unbound secondary antibody and PANSORBIN® cells can be incubated with the sample sequentially, following primary antibody incubation. PANSORBIN® Step: 1. Add at least 10X the amount of PANSORBIN® cells (alone or bound to secondary antibody) needed to precipitate the primary (or secondary) antibody. PANSORBIN® cells bind about 2 mg of human IgG/ml. Typically, add 10-30 µl of PANSORBIN® cells per immunoprecipitation. This quantity gives a visible pellet. 2. Incubate for 1-2 h on ice, mixing regularly. 3. Centrifuge at 3000 x g for 5 min, or at maximum speed in a microfuge for 1 min at 4°C. 4. Wash PANSORBIN® pellet 2-3 times with lysis buffer. 5. If samples are to be loaded onto a polyacrylamide gel, the PANSORBIN® pellet can be resuspended in sample buffer, boiled for 10 min, centrifuged quickly (30 s in a microfuge at 20°C). Load the supernatant onto the gel. If a high background is observed, it may be necessary to pre-clear lysates, prebind the antibody to PANSORBIN® cells, or use a stronger lysis buffer (e.g. RIPA). This protocol is meant to serve as a guideline and may need to be modified for specific applications.
