Product Overview
This rabbit polyclonal antibody targets dual specificity protein kinase TTK in human, mouse and rat samples and is validated for Western blot, IHC, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 97.1 kDa, and the supplier reports an observed band at about 97 kDa.
TTK (also called MPS1) is a dual-specificity kinase that is a central component of the spindle assembly checkpoint. At kinetochores it phosphorylates KNL1, MAD1 and other targets to hold cells in mitosis until chromosomes are properly attached, and it helps correct faulty attachments; it is studied as a cancer drug target.

Samples with a confirmed band (WB): human A549 cells, human HepG2 cells, rat testicular tissue, mouse spleen tissue, mouse RAW264.7 cells.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 5–20% gradient SDS-PAGE under reducing conditions, 50 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 0.5 µg/mL overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Samples with confirmed staining (IHC): human rectal cancer tissue, rat intestine tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
