Immunofluorescence analysis of Bcl-X Antibody was done on 70% confluent log phase A549 cells. The cells were fixed with 4% paraformaldehyde for 15 minutes, permeabilized with 0.25% Triton™ X-100 for 10 minutes, and blocked with 5% BSA for 1 hour at room temperature. The cells were labeled with Bcl-X Antibody (AHO0222) at 1µg/mL in 1% BSA and incubated for 3 hours at room temperature and then labeled with Alexa Flour 488 Rabbit Anti-Mouse IgG Secondary Antibody (A11059) at a dilution of 1:400 for 45 minutes at room temperature (Panel a: green). Nuclei (Panel b: blue) were stained with SlowFade® Gold Antifade Mountant with DAPI (S36938). F-actin (Panel c: red) was stained with Alexa Fluor 594 Phalloidin (A12381). Panel d is a merged image showing cytoplasmic and nuclear localization. Panel e is a no primary antibody control. The images were captured at 40X magnification.

This antibody reacts with both Bcl-XS (short) and Bcl-XL (long) proteins. The immunogenic sequence (aa 3-14) is conserved in human and mice.
Staining of formalin-fixed paraffin-embedded tissues requires boiling tissue sections in 10mM citrate buffer, pH 6.0, for 20 min followed by cooling at room temperature for 20 min. A recommended positive control is Hodgkin's lymphoma.
Bcl-X has two isoforms, Bcl-XL (long), a 241 amino acid protein, and Bcl-XS (short), a 178 amino acid protein lacking a 63 amino acid domain that is well-conserved among members of the Bcl-2 family. This family of proteins is an important regulator of apoptosis. Bcl xL forms heterodimers with BAX, BAK, and Bcl2, and its overexpression in tumor cells confers resistance against chemotherapeutic drugs. Bcl xL is phosphorylated on many sites including serine 62, a critical site for Bcl xL response to microtubule-damaging drugs such as taxol and vinblastine. Phosphorylation of serine 62 is thought to be mediated by Jun N-terminal stress kinase (JNK) signaling - negatively regulates the anti-apoptotic function of Bcl xL and controls the growth of neoplastic cells.
