There are a number of ELISA Kits available for the measurement of Myeloid Cell Leukemia Sequence 1, another term for the human protein, MCL1 apoptosis regulator, BCL2 family member. Other synonyms may include: BCL2 family apoptosis regulator, MCL1 BCL2 family apoptosis regulator, bcl-2-like protein 3, myeloid cell leukemia 1, and myeloid cell leukemia ES. It is encoded by the MCL1 gene to yield a protein 350 amino acids in length and 37.3 kDa in size. However, there are up to 2 reported isoforms. The protein is categorized into the Bcl-2 family. Versions of Myeloid Cell Leukemia Sequence 1 are present in other organisms, including: Mouse, Rat, Frog, Chicken.
