WebPhospho-Chk1 (Ser345) Antibody detects endogenous levels of Chk1 only when phosphorylated at serine 345. This antibody does not cross-react with Chk1 when phosphorylated at other sites. Species Reactivity: Human, … WebWe also found that pS345 Chk1, which is a measure of DNA damage, was induced in marker-positive cells but not in the marker-negative cells. These data demonstrate that Chk1 inhibition in combination with gemcitabine reduces both the percentage and the tumor-initiating capacity of pancreatic cancer stem cells. Furthermore, the finding that the ...
