Overview

  • Product name

    Anti-pan Lamin antibody [X67, X167, X233]

  • Description

    Mouse monoclonal [X67, X167, X233] to pan Lamin

  • Host species

    Mouse

  • Specificity

    Lamins do not appear to be universally distributed among different cell and tissue types. ab20740 recognizes the karyoskeleton, i.e. the intermediate filament proteins of the nucleus. Reacts with Lamin isotypes of Mr 60-75 kDa (LA, LI, LII, LIII, B1, B2, C). Other cell/tissue types have not been tested.

  • Tested applications

    Suitable for: WB, ICC/IFmore details

  • Species reactivity

    Reacts with: Mouse, Cow, Human, Xenopus laevis, Kangaroo, Rainbow trout

  • Immunogen

    cell preparation: Nuclear pore complex-lamina fraction of Xenopus laevis (XLKE-A6 cells).

      ab20740 at a 1/50 dilution staining human U2 OS cells by Immunocytochemistry/Immunofluorescence. The cells were Paraformaldehyde fixed and incubated with the antibody for 16 hours. Bound antibody was detected using an Alexa- Fluor ® 488 conjugated goat anti-mouse IgG.

      The antibody was found to stain equally well when used at a dilution of 1/250.

    Question

    Will this antibody cross-react with Lamin C? What samples were used to test this antibody in Western blotting?

    Answer

    Thank you for your enquiry and patience. This product is a mixture of 3 clones [X67, X167, X233] and two of the clones, X67 and X167, do react with Lamin C. I'm not able to obtain information at this time on exactly what samples were used to test this antibody. Please contact us again if you have any additional questions.

    Answer

    Thank you for contacting me regarding the problems that you have experienced using this Ab. Where an Ab is giving non specific staining I would suggest decreasing the concentration at which the primary Ab is used at from 1/50 to 1/100 rather than using the Ab at the higher concentration of ½ and undiluted, the reviewer mentions that using a concentration of 1/250 has been observed to give the same results. I would also advise that you use saponin as a permeabalization reagent (5-10ug/ml) rather than Triton X-100. Triton-X 100 will destroy cellular membranes since the target is located in the nuclear membrane this may be what is resulting in non specific binding, releasing antigen into the cytoplasm. Saponin is a detergent that permeabalizes the cell membrane of eukaryotic cell membranes by interacting with cholesterol and is more gentle than Triton-X. Where membranes are not over treated with saponin they have the ability to reform. In addition to this the percentage of blocking reagent may be increased to 5% BSA this will also act to reduce the observed background staining. Please do not hesitate to get back in touch with me should you still experience problems.

    Answer

    Thank you for your enquiry. This product is a mixture of 3 monoclonal antibodies, Clones X67, X167, and X223. The specific epitope locations have not been determined. The reactivity to lamin isotypes in different species for each clone is listed on the datasheet. Please contact us again if you require further assistance.
