synthetic peptide corresponding to amino acids 422-436 located at the C-terminus of mouse LKB1, conjugated to KLH. This sequence is highly conserved (90%) in human LKB1.

General description

LKB1 is a serine/threonine kinase that functions as a tumor suppressor. LKB1 mediates several functions such as initiation of axons during neuronal polarization, spermiogenesis and hepatic glucose homeostasis. Mutations in LKB1 have been linked to Peutz-Jeghers syndrome . Anti-LKB1 antibody is specific for mouse, human and rat LKB1 (55 kDa). In immunoblotting, staining of LKB1 is specifically inhibited with the LKB1 immunizing peptide (mouse, amino acids 422-436).

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.


Anti-LKB1 antibody is suitable for use in western blot at 1:2,000-1:4,000 dilutions, using cytosolic fractions (S1) of mouse brain or whole cell extracts of rat fibroblasts (Rat-1 cell line) and human epidermoid carcinoma (A431 cell line). The antibody can also be used for immunofluorescence and microarray studies.
