Concentration: 125 µg/ml
RRID: AB_2075940
Storage Buffer: Aqueous buffered solution containing BSA, goat serum, and ≤0.09% sodium azide.
Regulatory Status: RUO
Preparation And Storage: Preparation And Storage Store undiluted at 4°C. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography.
Recommended Assay Procedures: Recommended Assay Procedures Immunohistochemistry: Clone 3/23 is recommended to test for immunohistochemical staining on acetone-fixed frozen sections or zinc-fixed paraffin sections of mouse spleen or thymus. IHC of formalin-fixed paraffin embedded sections is not recommended .  The isotype control recommended for use with this antibody is purified rat IgG2a (Cat. No. 559073). For optimal indirect immunohistochemical staining, the 3/23 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 (multiple adsorbed) (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 a DAB substrate 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. An isotype control should be used at the same concentration as the antibody of interest. 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.
