Overview

  • Product nameAnti-Lamin B1 antibody [119D5-F1]
    See all Lamin B1 primary antibodies
  • Description
    Mouse monoclonal [119D5-F1] to Lamin B1
  • SpecificityReacts with an epitope located C-terminal of residue 231 in lamin B1. Reacts against lamin B1, does not cross react with lamin B2. Lamins do not appear to be universally distributed among different cell and tissue types. ab8982 has been shown to react with HeLa and 3T3 cells in immunocytochemistry. Other cell/tissue types have not been tested.

  • Species reactivity
    Reacts with: Mouse, Rat, Sheep, Rabbit, Cow, Dog, Human, Zebrafish
  • Immunogen

    Tissue, cells or virus corresponding to Rat Lamin B1 (C terminal). Immunogen = Purified Rat liver lamins

  • EpitopeC-terminal to residue 231.

Target

  • FunctionLamins are components of the nuclear lamina, a fibrous layer on the nucleoplasmic side of the inner nuclear membrane, which is thought to provide a framework for the nuclear envelope and may also interact with chromatin.
  • Involvement in diseaseDefects in LMNB1 are the cause of leukodystrophy demyelinating autosomal dominant adult-onset (ADLD) [MIM:169500]. ADLD is a slowly progressive and fatal demyelinating leukodystrophy, presenting in the fourth or fifth decade of life. Clinically characterized by early autonomic abnormalities, pyramidal and cerebellar dysfunction, and symmetric demyelination of the CNS. It differs from multiple sclerosis and other demyelinating disorders in that neuropathology shows preservation of oligodendroglia in the presence of subtotal demyelination and lack of astrogliosis.
  • Sequence similaritiesBelongs to the intermediate filament family.
  • Post-translational
    modifications
    B-type lamins undergo a series of modifications, such as farnesylation and phosphorylation. Increased phosphorylation of the lamins occurs before envelope disintegration and probably plays a role in regulating lamin associations.
  • Cellular localizationNucleus inner membrane.

Anti-Lamin B1 antibody [119D5-F1] images

  • Methanol fixed HeLa and 3T3 cells (ab7179) were stained with ab8982 (1/50 and 1/20 respectively). The cells were fixed in 100% methanol for 6 minutes at -20°C. ab8982 clearly stains the nuclear envelope with very little backgrouns staining.

  • Immunohistochemistry on frozen sections of human colon showing nuclear lamina staining in epithelial and connective tissue cells
  • Immunohistochemistry on frozen sections of swine liver showing nuclear lamina staining in hepatocytes
  • Overlay histogram showing HeLA cells stained with ab8982 (red line). The cells were fixed with 100% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum (ab7481) / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab8982, 1µg/1x106 cells) for 30 min at 22°C. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22°C. Isotype control antibody (black line) was Mouse IgG1 [ICIGG1] (ab91353, 2µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed.
