    Location of antibody epitopes. Shown is a schematic of the Ca v 1.2 α 1 1.2 subunit, in which regions used as immunogens for the depicted antibodies are identified by arrows. Exact residues are listed in the table and numbered according to α 1 1.2 given in Gene Bank Accession number CAA33546. FP1, CNC1, and ACC-003 are directed against the loop between domains II and III, pS1700 against phosphorylated S1700, pS1928 against phosphorylated S1928, and CNC2 against residues 2122-2138 of α 1 1.2, which are ~40 residues upstream of the very C terminus of α 1 1.2.

    Article Snippet: Concordant with this idea, neither the ACC-003 antibody that we received from Alomone Labs that recognized a 130 kDa band in WT and cKO brains nor our CNC1 antibody recognized the strong 150 kDa band seen with FP1 in brain lysate.

    Techniques:

    Differential recognition of the strong 150 kDa FP1 band in lysate and weak 150 kDa band by FP1, CNC1, and ACC-003 after IP of α 1 1.2 with FP1. Immunoblots with CNC1 ( A , B ), FP1 ( C ), and ACC-003 ( D , E ) of Triton X-100 extracts from WT mice (lysate) and after immunoprecipitation with FP1 from cKO and WT mice. Gels were polymerized from 8% acrylamide. Note that a weak 150 kDa band is detected by CNC1, FP1, and ACC-003 after enrichment of α 1 1.2 by immunoprecipitation with FP1 but the strongly immunoreactive 150 kDa band detected by FP1 in lysate is not detectable by either CNC1 or ACC-003.
