Scientific Data

Western Blot Detection of Human Frk antibody by Western Blot. View Larger

Detection of Human Frk by Western Blot. Western blot shows lysates of MCF-7 human breast cancer cell line, K562 human chronic myelogenous leukemia cell line, and NTera-2 human testicular embryonic carcinoma cell line. PVDF membrane was probed with 2 µg/mL of Goat Anti-Human/Mouse/Rat Frk Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3766) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). A specific band was detected for Frk at approximately 58 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: Frk

Fyn-related kinase (Frk) is a tyrosine kinase of the Src family. Also known as Rak, Gtk, and Iyk, Frk is predominantly expressed in epithelial tissues. Frk protein is 49% and 47% identical to Fyn and Csk, respectively. Src family kinases regulate an array of cellular processes, including growth factor signaling, cytoskeleton dynamics, and cell proliferation.
