Target

  • Function

    Lamins 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 disease

    Defects 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 similarities

    Belongs 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 localization

    Nucleus inner membrane.

      ab8982 staining Lamin B1 in wild-type HAP1 cells (top panel) and LMNB1 knockout HAP1 cells (bottom panel). The cells were fixed with 100% methanol (5min), permeabilized with 0.1% Triton X-100 for 5 minutes and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1% PBS-Tween for 1h. The cells were then incubated with ab8982 at 0.5μg/ml and ab202272 at 1/250 dilution (shown in pseudocolour red) overnight at +4°C, followed by a further incubation at room temperature for 1h with a goat secondary antibody to Mouse IgG (Alexa Fluor® 488) (ab150117) at 2 μg/ml (shown in green). Nuclear DNA was labelled in blue with DAPI.

      Image was taken with a confocal microscope (Leica-Microsystems, TCS SP8).

    Question

    Dear Sir/Madam
    Thank you for your prompt response to Katarzyna Bielska concerning problems with Anti-Lamin B1 antibody (cat No ab8982). Of course, we prefer a new vial of your product as a free charge replacement. Because I’ve ordered your product, please send a new vial to the address below.

    Best regards

    Answer

    Thank you for confirming these details and for your cooperation. The details provided enable us to closely monitor the quality of our products.

    I am sorry this product did not perform as stated on the datasheet and for the inconvenience this has caused. As requested, I have issued a free of charge replacement with the order number 1136297.

    To check the status of the order please contact our Customer Service team and reference this number.

    Please note that this free of charge replacement vial is also covered by our Abpromise guarantee. Should you still be experiencing difficulties, or if you have any further questions, please do not hesitate to let us know.

    I wish you the best of luck with your research.

    Question

    I probably will ask for a new vial. I go to the holiday next week, so my colleague, will contact with you.
    Thank you for your help.

    Answer

    Have a lovely holiday and please ask your colleague to confirm if you wish to get a replacement and when.

    I look forward to hearing from you soon.

    Question

    A) Image: Both images labelled as PPAR. I am a bit confused. Could you attach an image for Lamin B1 which has the MW markers labelled properly?

    This is the problem, that I don't see lamin B1 - my control. I want to analyze levels of PPAR. I don't have problems with PPAR antibody but lamin B.

    B) Lysis buffer: Has the customer used RIPA buffer which contains not one - but a mixture of different proteinase inhibitors. It could be that the lower band (on the top image at around 55 kDa) represent some partially degraded protein.
    I have checked differnt coctails of inhibitors and PMSF give the best results.
    C) Dilution: Has the customer checked this antibody at a dilution of 1/100 to see if the intensity of the signal changes?
    I haven't. I don't think it will change something, if I don't see bands at a dilution 1/200.
    Best regards

    Question

    Dear Sir/Madam
    I am working with antibody ab 8982 (lot GR43517-7). I isolate nuclei and prepare nuclear protein extracts from rabbit liver. I have planned to use lamina B as my control. However, I don’t get signals from lamina B, but I can see other nuclear proteins. I store the antibody at +4°C and I have worked with the dilution 1:200. I have checked secondary antibody (they work). Do you have any information that somebody had problems with Anti-Lamin B1 antibody (lot GR43517-7)?
