ターゲット情報

  • 機能

    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.

  • 関連疾患

    Defects in LMNB2 are a cause of partial acquired lipodystrophy (APLD) [MIM:608709]. A rare childhood disease characterized by loss of subcutaneous fat from the face and trunk. Fat deposition on the pelvic girdle and lower limbs is normal or excessive. Most frequently, onset between 5 and 15 years of age. Most affected subjects are females and some show no other abnormality, but many develop glomerulonephritis, diabetes mellitus, hyperlipidemia, and complement deficiency. Mental retardation in some cases. APLD is a sporadic disorder of unknown etiology.

  • 配列類似性

    Belongs to the intermediate filament family.

  • 翻訳後修飾

    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.

    Answer

    Apologies for the misunderstanding but I thought you wanted a replacement instead of a refund. As requested I have credited the cost of ab8983. Your credit note number is ******.

    If you have any further questions on the credit note, please contact our accounts team at mailto:us.accounts@abcam.com and they will be happy to help.

    Please let me know if there is anything else I can help you with.

    Question

    Our lab has recently purchased the Anti-Lamin B2 antibody (catalogue #: ab8983) and we would like to also purchase the immunizing peptide corresponding to this antibody. However, there is no immunizing peptide listed on the data sheet for the Anti-Lamin B2 antibody. I was wondering if you have an immunizing peptide to this antibody and if so what is its catalogue number? Thank you,

    Read More
    Answer

    Thank you for your enquiry. Unfortunately, this product was not made from an immunizing peptide, but from a detergent insoluble fraction of potoroo cell line PtK1. Therefore, the immunizing peptide does not exist for this product. I am sorry I can't be of more assistance in this occasion but if there is anything else that I can help you with, please do not hesitate to contact me.

    Question

    I tested an antibody ab9883 Lamin B2 on rat tissue. 60ug of nuclear extraction prepared from rat brain was loaded on 15% of tris polyacrylamide gel. I used Precision Plus Protein Standards Dual color Marker, which recognizes protein bands between 250kDa and 10 kDa. Lamin B2 was diluted 1:100. A secondary antibody , alexa Fluor 680 goat anti mouse, was choosen to incubate a membrane 1 hr at room temperature with dilution 1:4000. Li-COR system showed that only one band with the size 50 kDa was detected. No other bands around it! So, does anyone have comments for that? Your product description says that a band should be detected approximately 67-65 kDa on mouse human hamster and Xenopus laevis.

    Answer

    Thank you for your feeback on your experience of ab8983 in your rat brain samples. We have not tested the antibody in this species so it maybe that the protein is truncated or smaller in this species or tissue. Brain contains relatively few nuclei and is therefore not the preferable tissue for the isolation of lamins, I therefore think it is best to run a positive control along your samples, such as NCI-H125 nuclear cell lysate as used in the paper by Machiels BM et al.( Nuclear lamin expression in normal testis and testicular germ cell tumours of adolescents and adults. J Pathol 182:197-204 (1997)). I have included on the datasheet the protocols from that paper to help you, please click on the link below which will take you to the datasheet. I hope this information will help you, please let us know how you get on, we look forward to receiving your review,

    Answer

    Thank you for your enquiry and I'm sorry to hear that you are experiencing difficulty with ab8983. At this point I would like to make the following suggestions. Try using nuclear extract rather than whole cell extract, and with the nuclear extract incubate overnight at 4C with the primary diluted to 1:50. Also, I see that you mentioned loading 15-30 ul/lane - do you mean 15-30 ug protein per lane? Please make sure that you are loading at least 30 ug protein. If these suggestions do not help and you have purchased the antibody in the past 90 days I would be happy to issue a refund or credit note to you. Have a nice weekend!
