Description

The HI111 monoclonal antibody reacts with human CD11a, the 180 kDa integrin α_L, also known as the lymphocyte function associated antigen-1 (LFA-1) α chain. LFA-1, formed by non-covalent association of CD11a with CD18 (integrin β₂), serves as an important adhesion molecule involved in lymphocyte and granulocyte function. CD54 (ICAM-1), CD102 (ICAM-2), and CD50 (ICAM-3) are ligands for LFA-1. CD11a is expressed by all leukocytes.

Applications Reported

For research use only, not for diagnostic or therapeutic use. This HI111 antibody has been reported for use in flow cytometric analysis, and immunohistology staining of frozen tissue sections. It has also been reported in blocking of CD11a function in mixed lymphocyte reactions. (Please use Functional Grade purified HI111, cat. 16-0119, in functional assays.)

Applications Tested

The HI111 antibody has been tested by flow cytometric analysis of human peripheral blood leukocytes. This can be used at less than or equal to 1 μg per 100 μl blood (or per 1 million cells in 100 μl total staining volume). It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.
