|Recombinant Human PBK protein (Catalog#10729-H08B)|
|0.2 μm filtered solution in PBS with 5% trehalose|
|This antibody was produced from a hybridoma resulting from the fusion of a mouse myeloma with B cells obtained from a mouse immunized with purified, recombinant Human PBK / TOPK (rh PBK; Catalog#10729-H08B; NP_060962.2; Met 1-Val 322). The IgG fraction of the cell culture supernatant was purified by Protein A affinity chromatography.|
|Human PBK / TOPK / CT84|
No cross-reactivity in WB and ELISA with
Insect cell lysate
WB: 5-10 μg/mL
ELISA: 0.5-1 μg/mL
This antibody can be used at 0.5-1 μg/mL with the appropriate secondary reagents to detect Human PBK. The detection limit for Human PBK is 0.16 ng/well.
|This antibody can be stored at 2℃-8℃ for one month without detectable loss of activity. Antibody products are stable for twelve months from date of receipt when stored at -20℃ to -80℃. Preservative-Free.|
Sodium azide is recommended to avoid contamination (final concentration 0.05%-0.1%). It is toxic to cells and should be disposed of properly. Avoid repeated freeze-thaw cycles.
PDZ binding kinase (PBK), also known as TOPK (T-LAK cell-originated protein kinase), is a serine/threonine kinase related to the dual specific mitogen-activated protein kinase kinase (MAPKK) family, and has all the characteristic protein kinase subdomains and a C-terminal PDZ-binding T/SXV motif. PBK is expressed in the testis restrictedly expressed in outer cell layer of seminiferous tubules, as well as placenta. PBK may be enrolled in the activation of lymphoid cells and support testicular functions, with a suggested role in the process of spermatogenesis.This mitotic kinase phosphorylates MAP kinase p38 and seems to be active in mitosis. When phosphorylated, PBK forms a protein-protein interaction with tumor suppressor p53 (TP53), leading to TP53 destabilization and attenuation of G2/M checkpoint during doxorubicin-induced DNA damage. The expression level of PBK is thus upregulated in a variety of neoplasms including hematological malignancies.
