This product was assayed by immunoblot and found to be reactive against NFkB cRel at a dilution of 1:1000 followed by reaction with Peroxidase conjugated Affinity Purified anti-Rabbit IgG [H&L] (Goat) code #611-1302. Anti-NFkB cRel is suitable for the detection by immunoblot of human NFkB cRel. No reaction was observed against the analogous Mouse protein. This product was also tested in a gel supershift assay and found to be reactive against all cRel containing human NFkB complexes using 0.5 to 1.0 µl per assay.
