Background
Caveolae are specialized plasma membrane associated organelles that participate in numerous cellular functions including endocytosis, potocytosis, transcytosis, signal transduction and cholesterol trafficking. The major proteins that form caveolae are the caveolins of which there are three major isoforms. Caveolin-2 has been shown to positively regulate caveolin-1-dependent caveolae biogenesis; this phenomenon is contingent on the phosphorylation of caveolin-2 on serine 23 and 36. |
Antigen
Rabbits were immunized with a synthetic peptide based on amino acid residues 18-31 of caveolin-2 phosphorylated on Ser23. Antibodies were purified by peptide affinity chromatography. |
Application Notes
An ~20 kDa band is observed. |

|
Lysates from LNCaP cells expressing nonphosphorylated and phosphorylated caveolin-2 were left untreated (-) or treated with (+) calf intestinal phosphatase (CIP). The phosphospecific caveolin-2 (Ser23) (Cat No.IMG-5013) recognized the untreated, but not the CIP-treated lysate. |
