Our Abpromise guarantee covers the use of ab8221 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
Flow Cyt Use a concentration of 2 µg/ml. ab170190-Mouse monoclonal IgG1, is suitable for use as an isotype control with this antibody.
IP Use at an assay dependent concentration. Excellent antibody for immunoaffinity purification of LFA-1 complex.
Functional Studies Use at an assay dependent concentration. The antibody MEM-25 partially blocks binding of LFA-1 complex to ICAM-1.


  • 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.
