Species cross-reactivity is determined by western blot.
Applications Key: W=Western Blotting, IP=Immunoprecipitation, IF-IC=Immunofluorescence (Immunocytochemistry),
Specificity / Sensitivity
Phospho-Lamin A/C (Ser22) (D2B2E) XP® Rabbit mAb recognizes endogenous levels of lamin A/C protein only when phosphorylated at Ser22.
Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Ser22 of human lamin A/C protein.
Confocal immunofluorescent analysis of HeLa cells, untreated (left) or hydroxyurea-treated (right), using Phospho-Lamin A/C (Ser22) (D2B2E) XP® Rabbit mAb (green). Actin filaments were labeled with DyLight™ 554 Phalloidin #13054 (red). Blue pseudocolor = DRAQ5® #4084 (fluorescent DNA dye).
Western blot analysis of extracts from HeLa, NIH/3T3, and C6 cells, treated with either hydroxyurea (4 mM, 20 hr; +) to induce G1/S phase or Paclitaxel #9807 (100 nM, 20 hr; +) to induce G2/M phase, using Phospho-Lamin A/C (Ser22) (D2B2E) XP® Rabbit mAb (upper) and Lamin A/C Antibody #2032 (lower).
Immunoprecipitation of phospho-Lamin A/C (Ser22) from extracts of HeLa cells treated with Paclitaxel #9807, using Rabbit (DA1E) mAb IgG XP® Isotype Control #3900 (lane 2) or Phospho-Lamin A/C (Ser22) (D2B2E) X® Rabbit mAb (lane 3). Lane 1 is 10% input. Western blot analysis was performed using Phospho-Lamin A/C (Ser22) (D2B2E) XP® Rabbit mAb.
Lamins are nuclear membrane structural components that are important in maintaining normal cell functions such as cell cycle control, DNA replication, and chromatin organization (1-3). Lamin A/C is cleaved by caspase-6 and serves as a marker for caspase-6 activation. During apoptosis, lamin A/C is specifically cleaved into a large (41-50 kDa) and a small (28 kDa) fragment (3,4). The cleavage of lamins results in nuclear dysregulation and cell death (5,6).
Phosphorylation of lamin A/C at Ser22 was identified in vivo in several cell lines by mass spectrometry analysis in proteomic screens. The surrounding sequence is a typical MAPK/CDK phosphorylation motif, which implicates a role in the cell cycle and mitosis (7-11).
