There are a number of ELISA Kits available for the measurement of CTF18, chromosome transmission fidelity factor 18, another term for the human protein, chromosome transmission fidelity factor 18. Other synonyms may include: chromosome transmission fidelity protein 18 homolog, C321D2.3 (novel protein), C321D2.4 (novel protein), CTF18 chromosome transmission fidelity factor 18 homolog, some homology with holliday junction DNA helicase RUVB like, C16orf41, and C321D2.2. It is encoded by the CHTF18 gene to yield a protein 975 amino acids in length and 107.4 kDa in size. However, there are up to 3 reported isoforms. The protein is categorized into the Activator 1 small subunits family, CTF18 subfamily. Versions of CTF18, chromosome transmission fidelity factor 18 are present in other organisms, including: Mouse, Rat, Zebrafish, Frog, Chicken.
