Gabr, West Virginia University, Dept of Pharmocology and Toxicology, Morgantown, WV. Introduction Secondary antibodies are host antibodies that bind to primary antibodies or antibody fragments. They are typically labeled with probes that make them useful for detection, purification or sorting applications. Secondary antibodies may be polyclonal antibodies or monoclonal antibodies. Polyclonal antibodies lack the specificity of monoclonal antibodies but frequently have higher sensitivities because polyclonal antibodies are a mixture of antibodies that may include very high affinity antibodies. Cloning may not effectively select the highest affinity antibody from a polyclonal host. Secondary antibodies are available with specificity for whole Ig molecules or antibody fragments such as the Fc or Fab regions. Sigma s polyclonal secondary antibodies are produced from the serum of host animals including, but not limited to, mouse, rabbit, goat, and sheep. Monoclonal secondary antibodies are produced from mouse hybridoma clones. Secondary antibodies are used in immunodetection, and immunoaffinity purification applications. Immunodetection applications include enzyme linked immunosorbent assays (ELISA); Western blotting, immunohistology, immunoblotting, immunostaining and cell based assays, and high throughput cell-based screening assays (HTS). Also, secondary antibodies are useful for fluorescence activated cell sorting or FACS. Sigma s commitment to manufacture and offer high quality antibodies at a competitive price is only the beginning. Sigma recognizes the importance of an ongoing partnership between the manufacturer and the customer. In the Sigma tradition, we will continue to emphasize service and provide all possible assistance to you: through customer service, technical service, and our award winning online tools, such as the Antibody Explorer and Your Favorite Gene; all of which allow you to search and browse for antibodies in a wide variety of ways. Jurkat cell nuclear extracts were separated on SDS- PAGE and blotted with Monoclonal Anti-MECP2, (lane 1) clone Men-8 (Cat. No. M7443); (lane 2) clone Mec-168 (Cat. No. M6818). The antibody was developed with Goat Anti-Mouse IgG (Fab specific)-peroxidase (Cat No. A2304) and a chemiluminescent substrate.

72 55 Order 800-325-3010 Technical Service 800-325-5832 3 26 The Ideal Anti-Rabbit Secondary Antibody for Western Blotting 43 34 Sigma s Mouse Anti-Rabbit IgG, Native, clone RabT-50 does not recognize denatured rabbit IgG. This feature is extremely useful in applications where the immuno pre ci pi ta ting and detecting antibodies are both produced in rabbit. In the example, this function is specifically demonstrated in the negative control lanes. Using Anti-Rabbit IgG, Native (Cat. No. R2655) the negative control lanes are clear in Panel A. However in Panel B, if a traditional Anti-Rabbit secondary is applied, the heavy chain of the immunoprecipitating antibody interferes and masks the sample bands. This antibody is especially valuable when the protein of interest has a molecular mass around 50 kda, which can be masked by the denatured (heavy chain) IgG.
