|0.3 mg/mL of mouse anti-PBK monoclonal antibody. Dilute to a working concentration of 2 μg/mL in CBS before coating.|
|0.5 mg/mL mouse-anti-PBK monoclonal antibody conjugated to horseradish-peroxidase (HRP). Dilute to working concentration of 1 μg/mL in detection antibody dilution buffer before use.|
|Each vial contains 40 ng of recombinant PBK. Reconstitute with 1 mL detection antibody dilution buffer. After reconstitution, store at -20℃ to -80℃ in a manual defrost freezer. A seven-point standard curve usi ng 2-fold serial dilutions in sample dilution buffer, and a high standard of 4 ng/mL is recommended.|
|The minimum detectable dose of Human PBK / TOPK was determined to be approximately 62.5 pg/ml. This is defined as at least three times standard deviations above the mean optical density of 10 replicates of the zero standard.|
|The human PBK / TOPK ELISA Pair Set is for the quantitative determinationof human PBK / TOPK.
This ELISA Pair Set contains the basic components required for the development of sandwich ELISAs.
The Sino Biological ELISA Pair Set is asolid phase sandwich ELISA (Enzyme-Linked ImmunosorbentAssay). It utilizes a monoclonal antibody specific for PBK / TOPK coated on a 96-well plate. Standards and samples are added tothe wells, and any PBK / TOPK present binds to the immobilizedantibody. The wells are washed and a horseradish peroxidase conjugated mouse anti-PBK / TOPKmonoclonal antibody is thenadded, producing an antibody-antigen-antibody "sandwich". The wells are againwashed and TMB substrate solution is loaded, which produces color in proportionto the amount of PBK / TOPK present in the sample. To end theenzyme reaction, the stop solution is added and absorbances of the microwell are read at 450 nm.

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.
