Applications

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.

Application Abreviews Notes
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.

Target

  • FunctionIntegrin 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.
  • Tissue specificityLeukocytes.
  • Sequence similaritiesBelongs to the integrin alpha chain family.
    Contains 7 FG-GAP repeats.
    Contains 1 VWFA domain.
  • DomainThe integrin I-domain (insert) is a VWFA domain. Integrins with I-domains do not undergo protease cleavage.
  • Cellular localizationMembrane.

Anti-CD11a antibody [MEM-83] images

  • 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.
