This product was assayed by immunoblot and found to be reactive against NF-Y (B subunit specific) at a dilution of 1:2,000 followed by reaction with Peroxidase conjugated Affinity Purified anti-Rabbit IgG [H&L] (Goat) code #611-1302. Anti-NF-Y (B subunit specific) is suitable for the detection by immunoblot of human and mouse NF-Y. Minimal reactivity was observed against the A subunit of NF-Y. This product was also tested in a gel supershift assay and found to be reactive against NF-Y using 0.5 to 1.0 µl per assay. This product is suitable for immunohistochemistry in human thymus tissue at 1:500.
