Cat.No.

CSC-C0303

Description

Supposedly "established from the peripheral blood of a 72-year-old woman with acute myelomonocytic leukemia (AML FAB M4) in 1983"; however Creative Bioarray DNA fingerprinting and cytogenetic analysis established unequivocally that JOSK-I, JOSK-M and U-937 are identical; thus, JOSK-I is clearly a derivative of U-937

Why do we use HEPES in cell culture?

HEPES is widely used in cell culture, largely because it is better at maintaining physiological pH despite changes in carbon dioxide concentration (produced by aerobic respiration) when compared to bicarbonate buffers, which are also commonly used in cell culture.
