    CD11a 一次抗体 製品一覧
  • 製品の詳細
    Mouse monoclonal [MEM-83] to CD11a
  • 特異性
    The antibody MEM-83 reacts with CD11a (alpha subunit of human LFA-1), a 170-180 kDa type I transmembrane glycoprotein expressed on B and T lymphocytes, monocytes, macrophages, neutrophils, basophils and eosinophils.

  • 種交差性
    交差種: Human
  • 免疫原

    Tissue/ cell preparation (Human). Peripheral blood lymphocytes.

  • エピトープ
    The antibody recognizes an unique epitope on CD11a antigen (LFA-1 alpha chain) implicated in activation of LFA-1 complex.
  • 特記事項

    Abcam is committed to meeting high standards of ethical manufacturing and as such, we will be discontinuing this product, which has been generated by the ascites method, within the next year. We are sorry for any inconvenience this may cause. We would recommend antibody ab52895 as a replacement.

製品の特性

アプリケーション

Our Abpromise guarantee covers the use of ab3981 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

アプリケーション Abreviews 特記事項
Blocking Use at an assay dependent concentration. PubMed: 23039186
Flow Cyt Use a concentration of 1 µg/ml.
Functional Studies Use at an assay dependent concentration. The antibody MEM-83 directly induces the binding of T cells to purified ICAM-1. Using an in vitro-translated CDlla cDNA deletion series, the MEM-83 activation epitope was mapped to the "I" domain of the LFA-1 alpha subunit. The studies have therefore identified a novel LFA-1 activation epitope mapping to the I domain of LFA-1, which could play a role in the regulation of LFA-1 binding to ICAM-1.
IP Use at an assay dependent concentration.

ターゲット情報

  • 機能
    Integrin alpha-L/beta-2 is a receptor for ICAM1, ICAM2, ICAM3 and ICAM4. It is involved in a variety of immune phenomena including leukocyte-endothelial cell interaction, cytotoxic T-cell mediated killing, and antibody dependent killing by granulocytes and monocytes.
  • 組織特異性
    Leukocytes.
  • 配列類似性
    Belongs to the integrin alpha chain family.
    Contains 7 FG-GAP repeats.
    Contains 1 VWFA domain.
  • ドメイン
    The integrin I-domain (insert) is a VWFA domain. Integrins with I-domains do not undergo protease cleavage.

  • Transmigration of A375 Human melanoma cells, blocked using ab3981.

    Melanoma cells were labeled with 10 µM of lipophilic fluorescent dye for 20 minutes at 37°C. Cells were added to wells containing either 1 µg/ml of isotypic control, or 1 µg/ml of anti-CD11a (ab3981) or anti-CD18 (ab8220) antibodies. Melanoma cells were allowed to migrate at 37°C and 5% CO2 for 48 hours. Migration was observed under a fluorescence microscope.
