|ICC||Use at an assay dependent concentration.|
功能Potent inhibitor of cell death. Inhibits activation of caspases (By similarity). Appears to regulate cell death by blocking the voltage-dependent anion channnel (VDAC) by binding to it and preventing the release of the caspase activator, CYC1, from the mitochondrial membrane.
Isoform Bcl-X(S) promotes apoptosis.
组织特异性Bcl-X(S) is expressed at high levels in cells that undergo a high rate of turnover, such as developing lymphocytes. In contrast, Bcl-X(L) is found in tissues containing long-lived postmitotic cells, such as adult brain.
序列相似性Belongs to the Bcl-2 family.
结构域The BH4 motif is required for anti-apoptotic activity. The BH1 and BH2 motifs are required for both heterodimerization with other Bcl-2 family members and for repression of cell death.
翻译后修饰Proteolytically cleaved by caspases during apoptosis. The cleaved protein, lacking the BH4 motif, has pro-apoptotic activity.
细胞定位Mitochondrion membrane. Nucleus membrane. Mitochondrial membranes and perinuclear envelope.

ICC/IF image of ab2568 stained HeLa cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab2568, 1µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
ab2568 staining BCL-XL (green) in Mouse RAW 264.7 cells by ICC (Immunocytochemistry). Cells were fixed with paraformaldehyde, permeabilized by 0.1% Triton X-100 in 2% BSA for 15 minutes and blocked with 2% BSA for 1 hour at 22°C. Samples were incubated with primary antibody (1/250 in 2% BSA in PBS) for 16 hours at 4°C. An Alexa Fluor®488-conjugated Chicken anti-rabbit IgG polyclonal (1/750) was used as the secondary antibody.
WGA (red) = Alexa Fluor®568-conjugated Wheat Germ Agglutinin
