Recommended Assay Procedures: Recommended Assay Procedures Immunohistochemistry: This antibody may be used for the immunohistochemical staining of formalin-fixed paraffin-embedded sections of mouse spleen or thymus.  No pretreatment for antigen retrieval is required. This antibody has been reported to stain for all B cells but not plasma cells. The isotype control recommended for use with this antibody is purified rat IgG2a (Cat. No. 559073). For optimal indirect immunohistochemical staining, this antibody should be titrated (1:10 to 1:50 dilution) and visualized via a three-step staining procedure in combination with biotinylated polyclonal anti-rat Ig (Cat. No. 559286) as the secondary antibody and Streptavidin-HRP (Cat. No. 550946) together with the DAB detection system (Cat. No. 550880).  More conveniently, the anti-rat Ig HRP detection kit (Cat. No. 551013) can be used which contains the biotinylated secondary antibody, the antibody diluent, Streptavidin-HRP and DAB substrates for use in the staining procedure.
Product Notices: Product Notices Since applications vary, each investigator should titrate the reagent to obtain optimal results. Source of all serum proteins is from USDA inspected abattoirs located in the United States. 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. This antibody has been developed for the immunohistochemistry application. However, a routine immunohistochemistry test is not performed on every lot. Researchers are encouraged to titrate the reagent for optimal performance. An isotype control should be used at the same concentration as the antibody of interest.
