The BCL2A1 protein plays a critical role in resisting apoptosis triggered by IL-3 deprivation, suggesting its importance in the response of hematopoietic cells to external signals and may be involved in protecting endothelial cell survival during infection. It also inhibits serum starvation-induced apoptosis in mammary epithelial cells (HC11) . BCL2A1 Protein, Human (His) is the recombinant human-derived BCL2A1 protein, expressed by E. coli , with N-His labeled tag.
