BD, 553397, Purified Rat Anti-Mouse IgG2a/2b R2-40

The R2-40 monoclonal antibody specifically recognizes a common epitope, probably located in the CH1 domain, shared by mouse IgG2a, and IgG2b, of Igh-Ca and Igh-Cb haplotypes. It does not react with other Ig isotypes.
Purified Rat Anti-Mouse IgG2a/2b may be used as a primary reagent in immunofluorescent staining. For flow cytometric detection of intracytoplasmic IgG2a/2b, we recommend FITC Rat Anti-Mouse IgG2a/2b (Cat. No. 553399).
The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. Store undiluted at 4°C.
1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
2. 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.
3. Sodium azide is a reversible inhibitor of oxidative metabolism; therefore, antibody preparations containing this preservative agent must not be used in cell cultures nor injected into animals. Sodium azide may be removed by washing stained cells or plate-bound antibody or dialyzing soluble antibody in sodium azide-free buffer. Since endotoxin may also affect the results of functional studies, we recommend the NA/LE (No Azide/Low Endotoxin) antibody format, if available, for in vitro and in vivo use.
