Ready-to-use ELISA kits are available for the detection of NFkB p65, an alias of the protein, RELA proto-oncogene, NF-kB subunit. The official gene symbol is RELA. The kits can detect several species variants of the protein, including: human, mouse, rat, chicken, primate, guinea pig, and other mammalian. The protein, with a mass of 60.2 kDa and length of 551 residues, is reported to be cytoplasmic and nuclear. It may be known by other names, including: v-rel reticuloendotheliosis viral oncogene homolog A, v-rel avian reticuloendotheliosis viral oncogene homolog A, nuclear factor NF-kappa-B p65 subunit, NF-kappa-B transcription factor p65, NF-kappa-B p65delta3, and transcription factor p65, and NFKB3.
