特異性：This item recognises an epitope within the central region (IN) of human Myeloid cell leukaemia sequence 1 (MCL-1), an anti-apoptotic member of the Bcl-2 family of proteins, first identified in differentiating ML-1 myeloid cells, and expressed in many different cell lines, tissues and a variety of tumours. The MCL-1 protein, localised to intracellular membranes and particularly mitochondrial membranes, has since been isolated in two distinct isoforms, known as MCL-1 long (MCL-1L) and MCL-1 short (MCL-1S). MCL-1S has been identified as a pro-apoptotic splice variant of MCL-1L, missing the transmembrane and BH1 and BH2 (Bcl-2 homology) domains. Interaction between these two antagonistic variants can act to regulate cell survival. This item recognises both the MCL-1L (38kDa) and MCL-1S (30kDa) isoforms of MCL-1.
