Detection of Human Lck by Western Blot. Western blot shows lysates of MOLT‑4 human acute lymphoblastic leukemia cell line and Jurkat human acute T cell leukemia cell line. PVDF Membrane was probed with 0.5 µg/mL of Goat Anti-Human Lck Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3704) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). A specific band was detected for Lck at approximately XXX kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group XXX.

Lck (p56lck) is a member of the Src family of non-receptor tyrosine kinases. It was identified as a gene rearranged and over-expressed in the murine lymphoma LSTRA, most likely as a result of the insertion of Moloney murine leukemia virus DNA immediately adjacent to the gene. Lck behaves as a proto-oncogene and can lead to cell transformation upon activation. A number of human cancer cell lines show over-expression of Lck, pointing to a possible role for this kinase in the initiation and maintenance of the transformed state in human cancers.
