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 (Small Subunit) Antibody detects the small fragment of lamin A (and lamin C) resulting from cleavage at aspartic acid 230 by caspase-6. The antibody does not cross-react with full length lamin A or lamin C.

Source / Purification

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

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).
