Application Notes

Published Applications:
See references for more information. Individual optimization may be required.


This Bub1 antibody was raised against a recombinant protein corresponding to amino acids 281-419 of human Bub1.


Purified IgG in 70 mM Tris (pH 8), 105 mM NaCl, 31 mM glycine, 0.07 mM EDTA, 30% glycerol and 0.035% sodium azide. Sodium azide is highly toxic.



Bub1 is a serine-threonine protein kinase and an important regulator of cell division. It is essential for the G2/M mitotic spindle assembly/integrity checkpoint as well as critical for chromosome alignment. Bub1 is required for the assembly of a large number of proteins at the kinetochore, including CENP-E, CENP-F, BUB1B, MAD2L1 and PLK1. It plays a role in sister chromatid cohesion and it serves as a substrate for the anaphase-promoting complex. Bub1 mediates cell death in response to chromosome mis-segregation and acts to suppress spontaneous tumorigenesis.

Compatible Secondary Antibodies

Active Motif has developed a variety of high-quality secondary antibodies for most applications, with anti-rabbit and anti-mouse conjugates to a broad line of high-quality fluorescent molecules, as well as horse radish peroxidase (HRP).

Some products may be shipped at room temperature. This will not affect their stability or performance. Upon receipt, unconjugated antibodies may be stored at -20°C for up to 2 years. Fluorophore- & enzyme-conjugated antibodies should be stored at 4°C. Fluorophore-conjugated antibodies should be protected from light. Keep reagents on ice when not in storage; to avoid repeated freeze/thaw cycles, we recommend aliquoting items that will be stored frozen into single-use fractions prior to freezing.


This product is guaranteed for 6 months from date of receipt.
