Applications Key:  W=Western Blotting
Reactivity Key:  H=Human  M=Mouse  R=Rat
Species enclosed in parentheses are predicted to react based on 100% sequence homology. Species cross-reactivity is determined by Western blot.

Specificity / Sensitivity

Cleaved Lamin A (Asp230) Antibody detects endogenous levels of the large fragment of lamin A (and lamin C isotype) resulting from cleavage at aspartic acid 230. The antibody does not recognize full length lamin A.

Source / Purification

Polyclonal antibodies are produced by immunizing rabbits with a synthetic peptide (KLH coupled) corresponding to carboxy-terminal residues surrounding Asp230 in human lamin A. Antibodies are purified by protein A and peptide affinity chromatography.

Western Blotting

Western Blotting

Western blot analysis of extracts from HeLa cells, untreated or staurosporine-treated (1 µM), using Cleaved Lamin A (Asp230) Antibody (upper) or Lamin A Antibody #2032 (lower).

Background

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 (40-45 kDa) and a small (28 kDa) fragment (3,4). The cleavage of lamins results in nuclear disregulation and cell death (5,6).
