There are a number of ELISA Kits available for the measurement of PRP18 pre-mRNA processing factor 18 homolog (yeast), another term for the human protein, pre-mRNA processing factor 18. Other synonyms may include: pre-mRNA-splicing factor 18, PRP18 homolog, PRP18 pre-mRNA processing factor 18 homolog, PRP18 pre-mRNA processing factor 18 homolog(PRPF18), and PRP18 homolog. It is encoded by the PRPF18 gene to yield a protein 342 amino acids in length and 39.9 kDa in size. However, there are up to 2 reported isoforms. The protein is categorized into the PRP18 family. Versions of PRP18 pre-mRNA processing factor 18 homolog (yeast) are present in other organisms, including: Mouse, Rat, Frog.
