R-phycoerythrin (PE) is an accessory photosynthetic pigment found in red algae. It exists in vitro as a 240-kDa protein with 23 phycoerythrobilin chromophores per molecule. This makes PE one of the brightest fluorochromes for flow cytometry applications, but its photobleaching properties make it unsuitable for fluorescence microscopy.

Preparation and Storage
The polyclonal antibody was purified from antiserum by negative adsorption and affinity chromatography.
The antibody was conjugated with R-PE under optimum conditions, and unconjugated antibody and free PE were removed.
Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.
The polyclonal antibody solution was passed through solid-phase immunoadsorbent gels to minimize cross reactivity with rat, human, bovine, and horse serum proteins.
- Since applications vary, each investigator should titrate the reagent to obtain optimal results.

- 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.
As a second-step reagent for staining rat spleen and bone marrow leukocytes, Cat. No. 550589 is reactive with mouse primary antibodies having the IgG1, IgG2a, IgG2b, IgG3, IgM, and IgA isotypes. Minimal background staining of rat leukocytes occurs in the absence of primary antibody. In addition, it stains mouse peripheral B lymphocytes with little 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 Ig primary antibodies. However, we have observed that the reactivity of polyclonal second-step antibodies to mouse or rat IgM may be reduced after adsorption against Ig of rat or mouse, respectively. Because this anti-mouse Ig antibody was adsorbed with rat Ig, it may be weakly with some mouse IgM primary antibodies. In those cases, we recommend anti-mouse IgM mAb R6-60.2 (Cat. No. 553409) or anti-mouse Ig κ light chain mAb 187.1 (Cat. No. 559940). For optimal staining of human leukocytes, with mouse IgG and IgM primary antibodies, we recommend FITC-conjugated goat anti-mouse IgG + IgM (human-, bovine-, and horse-adsorbed, Cat. No. 555988).
