Recombinant Human Baculoviral IAP Repeat-Containing Protein 5/BIRC5 is produced with our E. coli expression system. The target protein is expressed with sequence (Met1-Asp142) of Human BIRC5.
纯度
> 95 % as determined by reducing SDS-PAGE.
过滤
0.2 μm filtered
内毒素水平
Less than 0.1 ng/μg (1 IEU/μg) as determined by LAL test
It is not recommended to reconstitute to a concentration less than 100 μg/mL. Dissolve the lyophilized protein in ddH2O. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
缓冲液
Lyophilized from a 0.2 μm filtered solution of 20 mM Tris, 0.1M NaCl, pH 7.5.
注意事项
Always centrifuge tubes before opening. Do not mix by vortex or pipetting.
储存条件
4 °C/-20 °C/-80 °C
储存方法
Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks. Reconstituted protein solution can be stored at 4-7°C for 2-7 days. Aliquots of reconstituted samples are stable at < -20°C for 3 months.
Baculoviral IAP Repeat-Containing Protein 5 (BIRC5) belongs to the IAP family. BIRC5 exists as a homodimer in the apo state and as a monomer in the CPC-bound state. BIRC5 contains one BIR repeat and is expressed only in fetal kidney and liver, and to lesser extent, lung and brain. BIRC5 functions as a multitasking protein that has dual roles in promoting cell proliferation and preventing apoptosis. BIRC5 is also a component of a chromosome passage protein complex (CPC), which is essential for chromosome alignment and segregation during mitosis and cytokinesis. BIRC5 acts as an important regulator of the localization of this complex.
