Lamin A/C (4C11) Mouse mAb (Alexa Fluor® 488 Conjugate) #8617
|IF-F IF-IC F||H M R Mk||Endogenous||Mouse IgG2a|
Reactivity Key: H=Human M=Mouse R=Rat Mk=Monkey
Species cross-reactivity is determined by western blot. Species enclosed in parentheses are predicted to react based on 100% sequence homology.
Specificity / Sensitivity
Lamin A/C (4C11) Mouse mAb (Alexa Fluor® 488 Conjugate) detects endogenous levels of lamin A and C proteins. It also reacts with the larger fragments of lamin A (50 kDa) and lamin C (41 kDa) produced by caspase cleavage during apoptosis. This antibody does not cross-react with lamins B1 and B2.
Source / Purification
Monoclonal antibody is produced by immunizing animals with a recombinant fragment of human lamin A protein.

Confocal immunofluorescent analysis of HeLa cells using Lamin A/C (4C11) Mouse mAb (Alexa Fluor® 488 Conjugate) (green). Actin filaments were labeled with DY-554 phalloidin (red).
Confocal immunofluorescent analysis of normal rat brain using Lamin A/C (4C11) Mouse mAb (Alexa Fluor® 488 Conjugate) (green). Actin filaments were labeled with DY-554 phalloidin (red). Blue pseudocolor = DRAQ5® (fluorescent DNA dye).
This Cell Signaling Technology antibody is conjugated to Alexa Fluor® 488 fluorescent dye and tested in-house for direct flow cytometry and immunofluorescent analysis in human cells. This antibody is expected to exhibit the same species cross-reactivity as the unconjugated Lamin A/C (4C11) Mouse mAb #4777.
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 disregulation and cell death (5,6).
