Figure Lengend Snippet: Immunoblot confirmation of regulated sites. Immunoblotting with phospho-specific antibodies confirmed phosphorylation of NKCC2 at Ser126 (A, Top) and Ser874 (A, Middle), NHE3 at Ser552 (B, Top), and β-catenin at Ser552 (C, Top) in paired vehicle- and hormone-treated mTAL suspensions. In each case (A–C), the respective holo-protein was also probed. Bar graph shows results of densitometry analysis of immunoblots. H, hormone treated; V, vehicle. Error bars indicate SEM (n = 3). The asterisk indicates statistical significance (P < 0.05).
Article Snippet: A rabbit polyclonal antibody (H7644) against total NHE3 was generated (Lofstrand Labs) against a synthetic peptide corresponding to amino acids 621–640 of rat NHE3 (RefSeq: {"type":"entrez-protein","attrs":{"text":"NP_036786","term_id":"6981562","term_text":"NP_036786"}} NP_036786 ) and affinity purified ( SI Materials and Methods ).
