Src-mCherry-epH4 is a mouse mammary epithelial cell line (epH4) expressing Src kinase fused to mCherry, a red fluorescent protein. The cell line is used to study Src kinase signaling and its role in epithelial cell function and cancer progression. It is particularly useful in experiments requiring visualization of Src activity within cells., These vials contain 1 million cells of Src-mCherry-epH4 cells. The cells are cryopreserved for long-term storage and should be thawed according to standard cell culture protocols.
