There are a number of ELISA Kits available for the measurement of BCL2-antagonist/killer 1, another term for the human protein, BCL2 antagonist/killer 1. Other synonyms may include: bcl-2 homologous antagonist/killer, BCL2-like 7 protein, apoptosis regulator BAK, bcl-2-like protein 7, pro-apoptotic protein BAK, BAK, and BAK-LIKE. It is encoded by the BAK1 gene to yield a protein 211 amino acids in length and 23.4 kDa in size. However, there are up to 2 reported isoforms. The protein is categorized into the Bcl-2 family. Versions of BCL2-antagonist/killer 1 are present in other organisms, including: Mouse, Rat.
