Survivin/BIRC5 Antibody (YA045)

Survivin/BIRC5 Antibody (YA045) is a Rabbit-derived and non-conjugated IgG monoclonal antibody, targeting to Survivin/BIRC5.

BIRC5, a versatile protein, plays dual roles in promoting cell proliferation and preventing apoptosis, highlighting its multifaceted functions. As a crucial component of the chromosome passage protein complex (CPC), BIRC5 is integral to chromosome alignment and segregation during mitosis and cytokinesis. It orchestrates CPC movement, directing its localization from the inner centromere in prometaphase to the midbody during cytokinesis, and contributes to central spindle organization by associating with polymerized microtubules. BIRC5 is intricately involved in recruiting CPC to centromeres during early mitosis, binding to histone H3 phosphorylated at 'Thr-3' (H3pT3). Functioning in collaboration with RAN, it aids in mitotic spindle formation, serving as a scaffold for delivering the RAN effector molecule TPX2 to microtubules. Beyond its mitotic functions, BIRC5 counters default apoptosis induction in G2/M phase, and its acetylated form represses STAT3 transactivation of target gene promoters. Additionally, it serves as an inhibitor of CASP3 and CASP7, essential for maintaining mitochondrial integrity and function. Existing as a monomer in the CPC-bound state, BIRC5 efficiently protects cells against apoptosis, while its dimeric form enhances tubulin stability. BIRC5 engages in a complex network of interactions with various proteins, such as histone H3, RAN, tubulin, XIAP/BIRC4, and DIABLO/SMAC, underscoring its pivotal regulatory functions in cellular processes.

• 
  Western blot analysis of extracts from Hela (lane 2(20μg) , Jurkat (lane 3(20μg) , RAW264.7 (lane 4(20μg),using Survivin Antibody (HY-P80352). Proteins were transferred to a PVDF membrane and blocked with 5% BSA in TBST for 2 hour at room temperature. The primary antibody and Loading control antibody (Beta Actin, HY-P80438, 1/3000) was used in 5% BSA in TBST at 4°C overnight. Goat Anti-Mouse/Rabbit IgG-HRP Secondary Antibody (HY-P8004/HY-P8001, 1/10,000) was used for 1 hour at room temperature.
• 
  Immunohistochemical analysis of paraffin-embedded Rat kidney tissue using Survivin Antibody (YA045). The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH 6.0) for 8 minutes. The tissues were blocked in QuickBlock for 20 minutes at room temperature, washed with ddH2O and PBS, and then probed with the primary antibody (HY-P80325, 1/200) in 4℃ overnight. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX.
