Alexa Fluor® 647 anti-ZAP70
Description
ZAP70 is a 70 kD protein tyrosine kinase associated with the zeta chain of the T cell receptor. It is expressed in T cells and NK cells and has been shown to be involved in T cell signaling. Defects in ZAP70 have been linked to selective T cell defects. The ZAP70 kinase undergoes multiple phosphorylation events after T cell receptor engagement and interacts with a number of proteins involved in signal transduction. Recently, ZAP70 has been identified as an important prognostic marker in B-cell chronic lymphocytic leukemia (B-CLL).
Formulation
Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide and 0.2% (w/v) BSA (origin USA).Recommended Usage
Each lot of this antibody is quality control tested by intracellular immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is 5 µl per million cells or 5 µl per 100 µl of whole blood. It is recommended that the reagent be titrated for optimal performance for each application.
* Alexa Fluor® 647 has a maximum emission of 668 nm when it is excited at 633 nm / 635 nm.
