BD, 554001, FITC Goat Anti-Mouse Ig Poly1270

Flow cytometry: As a second step reagent for staining rat splenocytes, it is reactive with mouse antibodies having the IgG1, IgG2a, IgG2b, IgG3, IgM, and IgA isotypes. However it has been reported that reactivity with some mouse IgM monoclonal antibodies is weak. Minimal background staining of rat leukocytes occurs in the absence of primary antibody. In addition, it stains mouse peripheral B lymphocytes with no non-specific staining of other splenic leukocytes. Therefore, it is useful as a primary reagent in immunofluorescent staining of mouse B cells and antibody-producing cells and as a secondary reagent for staining rat leukocytes with mouse antibodies, particularly mouse IgG. For optimal staining of human leukocytes, with mouse IgG and IgM primary antibodies, FITC goat anti-mouse IgG + IgM (human-, bovine-, and horse-adsorbed, Cat. No. 555988) is recommended.
The polyclonal antibody was purified from antiserum by negative adsorption and affinity chromatography. The antibody was conjugated with FITC under optimum conditions, and unreacted FITC was removed. Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.
1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
